Advantages include high strength along with excellent stress relaxation resistance and bend formability. Its properties are superior to those of beryllium copper alloy, long a representative standard for high-functionality copper alloys. Among the main uses are for connectors and camera modules in electronic devices such as smartphones and personal computers, taking advantage of the high strength and workability. Thanks to its outstanding stress relaxation resistance, use in automotive connectors has grown in recent years. As applications grow and the properties customers demand become more advanced as a result, we will continue our technology development toward improving properties and expanding our alloy lineup, so that such needs can be met in timely fashion. 動画を再生する Alloy name Composition Features Applications C1990 Cu-3Ti High strength, superior stress relaxation resistance Connectors, switches, jacks C1990HP Hyper Series Cu-3Ti Strength and bend formability superior to conventional titanium copper Connectors, switches, jacks C1990HP Foil (Titanium Copper Foil) Hyper Series Cu-3Ti A Hyper Titanium Copper foil product that has the highest level of strength of any copper alloy Connectors, camera modules C1990HC Cu-3Ti Electrical conductivity superior to conventional titanium copper Connectors, switches, battery terminals, jacks NKT322 Cu-3.2Ti-0.2Fe Strength (Yield strength) of 1 GPa or higher, along with excellent bend formability Connectors, switches, jacks Compare Composition and Properties Titanium Copper Alloy Composition and Properties Chemical Composition (wt%) Copper Alloy Name TiCu C1990 C1990HP C1990HC NKT322 Chemical Composition (wt%) Cu : Bal.
