Mechanical Properties

Processing and Fabrication

• Machining

C70260 can be machined using standard techniques, but it is harder than pure copper, so carbide tools are recommended.

• Forming

Can be cold-worked to achieve higher strength and hardness.

• Heat Treatment

Age-hardening can be applied to enhance mechanical properties.

• Joining

Can be soldered, brazed, or welded using appropriate techniques.

Availability

C70260 is typically available in the form of bars, rods, strips, and wires. The bars can be supplied in various diameters and lengths depending on the application requirements.
