Titanium copper is 2.9 to 3.5% copper, titanium-containing alloy is a high-reliability and high-performance environmentally friendly materials, particularly in the final stage of the alloy manufacturing process, the application temperature aging treatment. This effect is like rolling again, so that the material becomes harder and stronger, at the same time increase the conductivity and elongation, Electronic Materials Thin trend seems to complement each other. High Performance precipitation hardening the environmental copper alloy, high strength (1000N/mm ^ 2 ;), the excellent stress relaxation resistance and a higher heat capacity than the beryllium copper, can get a good minimum bending radius (R / t) and the higher the yield strength.
