Bending Wall Thickness Capacity Chart

Rogue Fabrication we work hard to provide our customers with the most complete and accurate tube bending information available. We do out part to ensure that your fab shop runs as smoothly as possible. Although the chart below is the result of tests we performed on purchased materials, we cannot guarantee that you will achieve the same results due to the wide variation in material quality from one mill to another. If you want to know what to expect from a specific material, we offer bending diagnostic services. If your tubing bender does not perform to the limits shown in this chart, please call so we can help diagnose the problem. The culprit is usually setup, material quality, or lubrication. The solutions to these issues are usually easy.

NOTE – With the recent release of our affordable and high-performance mandrel conversion, we have not yet tested all dies to the limit in terms of minimum wall thickness. We will continue to do testing and add the new dies we’re designing for the machine as we discover new lower limits to minimum bend radii. Please e mail us with your questions!

THIS SECTION WILL BE UPDATED SOON – If you have a new machine, just remember, the 601 has the same capacity as a 600 standard, the 605 matches the 600 HD, and the model 625 matches the 600 xHD! The TWR (Thin wall roller) improves performance (bend quality), but doesn’t extend the range of wall thickness the machine can bend.

*1) We do not guarantee performance on HREW. There are too many alloys and qualities of HREW being produced, and it gets mixed with and sold as other inferior tube products (at times). Good quality HREW tubing bends nearly the exact same as 1020 DOM. Ratings on aluminum (especially anything in a T6 temper) are based on our testing, read notes below on aluminum ratings.

*2) This capacity assumes 2 (TWO) pressure dies are in use, per the machine's operation instructions. If you are required to use 2 pressure dies, the material must be in contact with both, so plan your cut lengths and bending accordingly. Keep in mind you will have to use (2) pressure dies whenever you get to .156" wall or thicker. If you are bending .120" or .134" wall (or thinner, PLEASE do not use the back pressure die location (labeled HD only on the stickers). It will drastically reduce your bend quality.
M605(*3) To protect the pins in the machine, you will need to upgrade your M601 to an M605 to bend this size (by purchasing an HD kit, they are under $100 and sold with the tubing benders in our store).
NOTE: If you bend the thinnest material you can on ANY die, you will get the most deformation possible on that die. Meaning that the bends may appear flat on the outside of the bend. To avoid this, bend a thicker wall than the absolute minimum for a die, and bend on the largest CLR you can.

*1) We do not gurantee performance on HREW. There are too many alloys and qualities of HREW being produced, and it gets mixed with and sold as other inferior tube products (at times). Good quality HREW tubing bends nearly the exact same as 1020 DOM. Ratings on aluminum (especially anything in a T6 temper) are based on our testing, read notes below on aluminum ratings.
*2) This capacity assumes 2 (TWO) pressure dies are in use, per the machine's operation instructions. If you are required to use 2 pressure dies, the material must be in contact with both, so plan your cut lengths and bending accordingly. Keep in mind you will have to use (2) pressure dies whenever you get to .156" wall or thicker. If you are bending .120" or .134" wall (or thinner, PLEASE do not use the back pressure die location (labeled HD only on the stickers). It will drastically reduce your bend quality.
NOTE: If you bend the thinnest material you can on ANY die, you will get the most deformation possible on that die. Meaning that the bends may appear flat on the outside of the bend. To avoid this, bend a thicker wall than the absolute minimum for a die, and bend on the largest CLR you can.
TBD: To Be Determined. This means we have not completed testing yet. We offer testing on a case by case basis based on requests in some cases for these applications. If you have questions about capacity, you can always e mail us (link at top of page or menus).

*3) This number is based on other testing and extrapolation. It is not guranteed at this time. Contact us if you need testing done.
*4) This made a decent quality bend, but had a defect at the bend start - a dimple. If you're cutting up bends for (like for making headers), this will likely be OK.
*5) Bend quality was good in testing, but repeated wrinkles were present, and VERY minor (depth below 25% of material's wall thickness).
NOTE: If you bend the thinnest material you can on ANY die, you will get the most deformation possible on that die. Meaning that the bends may appear flat on the outside of the bend. To avoid this, bend a thicker wall than the absolute minimum for a die, and bend on the largest CLR you can.
Titanium alloy notes: We usually test 2.5AL-3V Titanium in CWSR (Cold Worked Stress Releived) state. This is a very strong alloy with excellent mechanical properties. It is also one of the most widely available alloys and conditions of titanium. We do not Test CP (commercially pure) or Inconel, although we can test your material (contact us).

Gauge Thickness Info	10 = .135, 11 = .119, 12 = .105, 13 = .090, 14 = .075, 15 = .067, 16 = .060, 18 = .048 (nominal)

*1) We do not gurantee performance on HREW. There are too many alloys and qualities of HREW being produced, and it gets mixed with and sold as other inferior tube products (at times). Good quality HREW tubing bends nearly the exact same as 1020 DOM. Ratings on aluminum (especially anything in a T6 temper) are based on our testing, read notes below on aluminum ratings.
*2) This capacity assumes 2 (TWO) pressure dies are in use, per the machine's operation instructions. If you are required to use 2 pressure dies, the material must be in contact with both, so plan your cut lengths and bending accordingly. Keep in mind you will have to use (2) pressure dies whenever you get to .156" wall or thicker. If you are bending .120" or .134" wall (or thinner, PLEASE do not use the back pressure die location (labeled HD only on the stickers). It will drastically reduce your bend quality.
*3) This number is based on other testing and extrapolation. It is not guranteed at this time. Contact us if you need testing done.
*4) This made a decent quality bend, but had a defect at the bend start - a dimple. If you're cutting up bends for (like for making headers), this will likely be OK.
*5) Bend quality was good in testing, but repeated wrinkles were present, and VERY minor (depth below 25% of material's wall thickness).
NOTE: If you bend the thinnest material you can on ANY die, you will get the most deformation possible on that die. Meaning that the bends may appear flat on the outside of the bend. To avoid this, bend a thicker wall than the absolute minimum for a die, and bend on the largest CLR you can.
Titanium alloy notes: We usually test 2.5AL-3V Titanium in CWSR (Cold Worked Stress Releived) state. This is a very strong alloy with excellent mechanical properties. It is also one of the most widely available alloys and conditions of titanium. We do not Test CP (commercially pure) or Inconel, although we can test your material (contact us).

Definitions / Notes

OD

Outside diameter

CLR

Center line radius. See M600 Bender Tech for more info.

Aluminum

We test primarily 6061-T6 because if that will bend, most other aluminum alloys will bend fine. Please see critical notes below on aluminum.

Carbon Steel

We test 1020 DOM and 4130N DOM primarily. We have found that good quality HREW bends the same, but there are many more alloys/grades of HREW, so it can be a source of inconsistency.

Stainless

We only test low carbon 304, 304L. In our experience, 316 and 316L bend similarly to the 304 alloys, and 409 bends better than them (less prone to wrinkling). Please look up Ferrari F355 headers before selecting 409 stainless for header applications!

M600 Basic

Standard Model 600 bender, no TWA (thin wall attachment).

M600 W/HD Kit

Model 600 HD, or a Standard M600 with HD kit ($65) added, and 2 pressure dies. See “HD Kit” in the dies section for more information.

M600 xHD

Xtreme heavy duty Model 600 (thicker frame and pins).

Thin Wall Attachment

Drop in subframe that allows ultra fine tuning of bend characteristics. As of 10-5-2016 this option is not yet for sale on our web page. Call us to get on the waiting list. This IS 100% compatible with all current M600 machines.

Mandrel Attachment

Bolt on frame that allows a metal mandrel (plug) to be installed inside the tubing where the bend is taking place. This holds the tubing open during the bend and allows bending of thinner material with amazing bend quality. This is ideal for headers, some exhaust work, and of course beautiful structural work like roll cages.

NPS

Nominal Pipe Size – for more info on pipe and tube, see M600 Bender Tech.

Sch

Pipe schedule. This is how pipe thickness is specified. Search online and you will find a pipe schedule with decimal thicknesses listed.

TBD

To Be Determined. As a small company that is rapidly expanding our product offerings and innovating in affordable metalworking technology, we frequently offer products before we have the chance to find their limit in all material sizes. That is the case where you see “TBD” on a die listing.

Important Capacity Considerations

Bending the absolute minimum that is listed in the table above will produce the highest amount of deformation possible on any given die. Going up even one thickness (like from .095 to .120, or .083 to .095) will typically improve bend quality significantly.

Aluminum is typically produced and sold in T6 temper (higher numbers are stronger and more brittle, whereas lower numbers like T0 are weaker and more ductile). The high T6 temper is ideal for strength and works well for machining and can be welded okay. It is far from ideal for cold working (bending) as it is prone to cracking. Sometimes you can’t see these cracks. Purchasing your material in T0 temper or de-tempering it down to T0 is the best defense against cracking. The material can be re-tempered back to T6 after cold working/forming is done at a heat treatment shop. We have bent .125″ wall aluminum in 6061-T6 without visible cracks in every rated application on our table shown above. The .250″ wall applications are more likely to crack and more likely to require bending to be done on material in T0 temper state.

We ALWAYS recommend you buy your material from a reputable supplier with material certifications and buy a small amount to test before you order a truckload. If you shop around until you find a better deal than anyone else can get, you are probably buying junk material. Don’t commit to 100 sticks before you test it in a tubing bender! Also, if you want to be 100% certain that your exact material will bend nicely on a die, we are happy to test it for you before you purchase, you can order the test from our online store.

Hydraulics systems

We offer 2 hydraulics systems for our machine. The air/hydraulic system covers the entire chart above. The electric/hydraulic system can be configured with a 5 ton or 9 ton cylinder, and the 5 ton maxes out at 1.5 x .156 wall square tube or 1.75 x .156 round tube, or 2.00 x .120 round tube. This is because the power of the electric/hydraulic system is biased more toward speed than outright tonnage on the 5 ton system. The larger 9 ton cylinder is slower but covers this whole capacity chart.

Warning

This page is NOT a substitute for machine operation instructions. You cannot tell from this capacity chart how to set up your specific model and revision of tubing bender to bend within these capacities. Your original instructions are the way to tell how to set up your machine and ensure you are being safe.
