16mm Solid T2 Copper Crank Prototypes Bent
High-precision CNC bending of 16mm solid T2 copper rods into crank hooks - two prototype pieces for a customer, formed without kinks or flattening.
Key Specifications
- Materials
- T2 red copper solid rod, 16 mm
Key Features
- Solid copper bent round, not flattened
- Soft metal handled with proper tooling
- Prototype pieces on production machines
- Copper conductivity kept for electrical use
Can a Machine Bend Solid Copper Without Flattening It?
Short answer: With the right die, copper bends rounder than steel. This video shows 16mm solid T2 copper rods formed into crank hook prototypes - soft metal, full sections, no kinks.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | Copper rod at die | Support close |
| 2 | First crank | Round bend |
| 3 | Hook head formed | Full profile |
| 4 | Prototype check | Two true pieces |
Key Applications
- Electrical busbar and contact arms
- Heat-exchanger crank links
- Decorative and museum hardware
Why Copper Is Tricky to Bend
| Steel | Copper (shown) |
|---|---|
| Springy, holds shape | Soft, takes tool marks |
| Wide radius forgiving | Needs polished tooling |
| Needs tight support dies |
FAQ
Why only two pieces? Customer prototyping - samples before a production run.
Can copper be plated after bending? Yes - nickel and tin plating run after forming.
