Molybdenum Copper Material

Molybdenum copper is a composite material of molybdenum and copper. Its performance is similar to that of tungsten copper, and it also has adjustable thermal expansion coefficient and thermal conductivity. However, the density of molybdenum copper is much smaller than that of tungsten copper, making it more suitable for aerospace and other fields.

Detailed introduction


Product Introduction

Molybdenum copper is a composite material of molybdenum and copper. Its performance is similar to that of tungsten copper, and it also has adjustable thermal expansion coefficient and thermal conductivity. However, the density of molybdenum copper is much smaller than that of tungsten copper, making it more suitable for aerospace and other fields.

 

Feature Of Product

1、No sintering activation elements such as Fe and Co are added to maintain high thermal conductivity

2、Excellent air tightness

3、Smaller density, more suitable for flight electronic equipment

4、Rolled plates can be provided to facilitate stamping parts

5、Provide semi-finished products or finished products with Ni/Au coating on the surface
