钛铜 Titanium Copper Alloys ●比磷青铜拥有更强的强度、为微型端子提供足够接触力的材料。

 Titanium copper has a higher strength than phosphor bronze, thus showing a higher contact force when used as a small contact terminal. ●

拥有与铍铜相同的强度，可以代替铍铜的使用。 Titanium copper has the same strength as beryllium copper. So, It can be used as an alternative material for beryllium copper. ●

拥有铜合金中好的耐应力缓和特性，高温环境下也可以保持良好的接 触力。

 Titanium Copper possesses excellent Stress Relaxation Resistance among copper alloys. Hence, high contact force can be maintained even in a high temperature environment. 化学成分和物理特性 Chemical composition and physical properties Alloy Chemical composition (%) Modulus of elasticity (GPa) Electrical conductivity (%IACS) C1990(HP) Cu-3.0Ti 127 12 NKT322 Cu-3.2Ti-0.2Fe 120 12 Alloy Temper 0.2% Yield strength (MPa) Elongation (%) Vickers Hardness MBR/t (BW) 0.15t C1990(HP) EH 860 17 300 1.0 SH 890 14 320 2.0 ESH 1030 3 340 ≧5.0 NKT322 H 850 18 300 0 EH 900 15 310 0.5 SH 950 10 330 1.0 ESH 1000 5 340 2.0
