C1990HP High-strength titanium copper for springs
Hyper Titanium Copper (C1990HP) was developed by further enhancing the properties of titanium copper alloy C1990.
Having the same chemical composition as C1990 but with higher strength and excellent bend formability, its properties equal or exceed those of beryllium copper (mill-hardened material). It is designed for use as a material in high-end switches, connectors, relays, and other electronic parts.
(We provide the Hi-Performance Series (HP) materials with the same composition as conventional products but with advanced material properties achieved by precision process control.)
