Titanium Copper Alloy
Titanium Copper NKT332 ― The best alternative to beryllium copper
GIGALLOY® High Strength Copper Alloy for Connectors (UNS Alloy No. C19910)
NKT322 GIGALLOY® is a proprietary alloy we developed by adding small amounts of iron to titanium copper and further improving processes. It is notably stronger than ordinary titanium copper and has better bend formability.
A beryllium-free ultra-high-strength copper alloy
Strength and bend formability equal to or greater than mill-hardened beryllium copper: In wide use as an alternative product
The highest level of stress relaxation resistance among copper alloys: Maintains contact force at high temperatures
