NKT322 GIGALLOY® from JX Nippon Mining & Metals is a proprietary alloy that was specifically developed by adding small amounts of iron to titanium copper and further enhancing processes. It is remarkably stronger compared to ordinary titanium copper and exhibits improved bend formability.
Features
- A beryllium-free ultra-high-strength copper alloy
- The greatest level of stress relaxation resistance among copper alloys: retains contact force at high temperatures
- Bend formability and strength equal to or higher than mill-hardened beryllium copper: widely used as an alternative product
Typical Applications
- Connectors
- Switches
- Jacks
