Titanium-copper alloy that has possesses strength exceeding 1000N/mm2 and superior bending workability.
A titanium-copper alloy which possesses top-class high strength and superior bending workability.
It is widely used in connectors that undergo complicated bending in such electronic devices as smartphones.
It has superior stress relaxation resistance in the temperatures as high as 200 °C.
As such, its application in connectors and switches for automobiles is increasing.
We have had many clients succeed in using this material as a substitute for high-strength beryllium copper.
