耐热冲击性

• The deposits are higher in hardness , wear resistance , heat impact resistance and a strong adhesion to the substrate cause the thermal expansion coefficient of ni - fe coating is very close to that of the cupper alloy . thus ni - fe coating is very suitable for a crystallizer used in continuous casting
  应用于结晶器上具有优异的特性，镀层的热膨胀系数与铜(铜合金)基体的热膨胀系数非常接近，使得镀层与基体的结合强度极高，镀层耐热性和耐热冲击性非常好，因此结晶器的使用寿命大大提高。
