Description

Data

Mechanical properties and bending formability of titanium copper alloy C1990HP is highly enhanced, while its chemical composition is maintained the same as conventional C1990's. This alloy is suitable to be used for switches, connectors, relays and other electronic components, and can be used as a subsititution of beryllium copper alloys.

"HP" stands for the high-performance series. Alloys of the high-performance series offer superior mechanical properties and bending formability to conventional alloys', while keeping the same chemical compositions as conventional ones'.
