Automotive: Mild steel is essential for high-precision chassis frames, roll cages, and exhaust systems. Its ability to absorb energy makes it ideal for safety-critical components.
-
Construction & Architecture: Used for both "bones" and "beauty," from structural trusses to custom door frames and decorative facades.
-
Industrial Manufacturing: Crucial for machine guards, equipment frames, and conveyor channels. Custom-bent brackets ensure seamless integration of heavy machinery.
-
Electronics & HVAC: Precision-bent enclosures protect sensitive controls, while custom ductwork and fan housings are tailored for optimal airflow.
-
Common Custom Bent Parts
-

160-tON mAX THiCKNESS VS LENGTH
BEND LENGTH | MAX THICKNESS | RECOMMENDED V-DIE | MIN INSIDE RADIUS |
|---|---|---|---|
10 FT (3050 MM) | 1/4" (6 MM) | 50 MM | 8 MM |
5 FT (1524 MM) | 3/8" (10 MM) | 80 MM | 13 MM |
2 FT (610 MM) | 5/8" (16 MM) | 125 MM | 21 MM |
1 FT (305 MM) | 3/4" (20 MM) | 160 MM | 26 MM |
Technical Details
Minimum Inside Radius: For Air Bending, the inside radius is not determined by the punch but rather then V Die opening.
-
Example: 50 mm V die, the radius is approximately 50x0.16 (16% of V Opening width) = 8 mm inside radius
10ft bend length at 1/4" Mild steel is at the max (160 tonne). If you steel has a higher carbon content, please know 1/4" will not be achieved over 10ft. Very important to detail your material requirements.
160-tON mAX THICKNESS VS LENGTH FOR STAINLESS
BEND LENGTH | MAX THICKNESS | RECOMMENDED V-DIE | MIN INSIDE RADIUS |
|---|---|---|---|
10 FT (3050 MM) | 3/16 | 40 MM | 7 MM |
5 FT (1524 MM) | 5/16" (8 MM) | 63 MM | 11 MM |
2FT (610 MM) | 1/2" (12 MM) | 100 MM | 17 MM |
1 FT (305 MM) | 5/8" (16 MM) | 125 MM | 22 MM |
Technical Details
-
Springback: Stainless steel has much higher "memory" than mild steel. While mild steel springs back 1–2°, stainless can spring back 3° to 5°. Ensure your tooling allows for enough over-bend (a 85° or 80° punch is often used for 90° air bends).
-
Work Hardening: Stainless hardens as it deforms. If you don't hit the bend in one clean stroke, or if you try to re-bend a part, the material becomes significantly harder, putting even more stress on your 160-ton limit.
-
Inside Radius: Because the material is tougher, the "natural" radius formed during air bending is slightly larger than mild steel, usually around 20% of the V-opening width.
Stainless Steel - Bending
Stainless steel bending at uMake.ca is the premier choice for projects requiring a combination of high strength, aesthetic appeal, and superior corrosion resistance. Unlike mild steel, stainless steel’s resistance to rust makes it indispensable for demanding environments.
Key Industry Applications
-
Food & Medical: Due to its hygienic properties, stainless steel is bent into commercial kitchen surfaces, medical trays, and pharmaceutical equipment. It withstands rigorous sanitization without degrading.
-
Marine & Outdoor: Its resistance to salt and moisture makes it the standard for boat railings, deck hardware, and outdoor signage.
-
Chemical & Energy: Used for pressure vessel supports and chemical piping, where the material must remain structural while exposed to caustic substances.
-
Architecture: Often used for high-end handrails, trims, and cladding where a polished, modern finish is as important as durability.
Common Custom Bent Parts
-
Sanitary Brackets: Corrosion-resistant mounts used in wash-down environments like breweries or hospitals.
-
Exhaust Components: High-grade headers and manifold tubes that must withstand extreme heat and oxidation.
-
Panel Enclosures: NEMA-rated boxes for outdoor electrical systems that protect against environmental elements.
-
Fluid Handling Tubes: Precision-bent tubing for hydraulic or pneumatic lines requiring high-pressure tolerance.
How Aluminum Grade and Grain Direction Affect Bending
Bending aluminum isn’t one-size-fits-all. Alloy choice, temper, grain direction, and bend radius all play a major role in whether a part forms cleanly—or cracks.
1. Aluminum Alloy & Temper Matter
Different aluminum grades behave very differently during bending:
3003-H14 — The Bending Grade
Highly ductile and extremely forgiving. This alloy bends easily, allows tight radii, and rarely cracks. Ideal for parts with aggressive bends.
5052-H32 — The Industry Standard
Stronger than 3003 while maintaining excellent formability. This is the go-to choice for enclosures and general sheet-metal work.
6061-T6 — The Structural Grade (Use with Caution)
Designed for strength, not forming. 6061-T6 is relatively brittle and prone to cracking when air-bent with a standard inside radius (≈ 1× material thickness). To bend successfully, a larger V-die must be used to create a larger inside radius.
2. Grain Direction Is Critical
Aluminum sheet is rolled, which creates a directional grain. This grain has a direct impact on bend strength:
Bending Across the Grain (Perpendicular)
The strongest and safest orientation. Material is less likely to crack and can tolerate a tighter bend radius.
Bending With the Grain (Parallel)
Significantly weaker. Cracking or splitting along the bend line is much more likely. If bending with the grain is unavoidable, increase the inside bend radius by using a wider V-die.
3. Minimum Bend Radius Guidelines
Unlike steel, aluminum cannot be bent with sharp tooling.
For 6061-T6, the recommended minimum inside bend radius is typically:
2× to 6× material thickness, depending on grain direction and tooling.
Rule of Thumb:
If the outside of your bend shows an “orange peel” texture or micro-cracks, the radius is too small. Increase the V-die width immediately to prevent structural failure.
160-tON mAX THiCKNESS VS LENGTH
Assumes a standard 6061-T6 alloy. If using softer alloys like 3003-H14, you can increase thickness slightly, but 160 tons is rarely the limiting factor for aluminum; material integrity is.
BEND LENGTH | MAX THICKNESS | RECOMMENDED V-DIE | MIN INSIDE RADIUS |
|---|---|---|---|
10 FT 3050 MM) | 3/8" (10 MM) | 80 MM | 13 MM |
5 FT 1524 MM) | 1/2" (12 MM) | 100 MM | 17 MM |
2 FT (610 MM) | 3/4"(20 MM) | 160 MM | 27 MM |
1 FT (305 MM) | 1" (25 MM) | 200 MM | 34 MM |
