W70Cu Tungsten Copper Alloy Electronic Package Plate Sheet Copper Tungsten Electrode Material

W70Cu30 Tungsten Copper Alloy Electronic Package Sheet Metal Electrode

1. W70Cu30 Tungsten Copper Alloy Electronic Package Sheet Metal Electrode :

Tungsten copper encapsulation sheet and heat sink material have both the low expansion characteristics of tungsten and the high thermal conductivity of copper. Wide range of applications.

W70 tungsten copper encapsulation sheet, as the name suggests, is a material composed of 70% tungsten and 30% copper, of which 30±2% copper, and the impurity tungsten is 0.5%. Compared with W50 and W60 tungsten-copper alloys, the density and hardness of W70 tungsten-copper alloy are higher, and the density is about 13.80g/cm3, and the hardness is not lower than HB175. However, its electrical conductivity has decreased to about 42IACS%, its bending strength is 790, and its softening temperature is ≥900℃.

3.WCu30 Tungsten Copper Alloy Electronic Package Sheet Metal Electrode Manufacturing Techniques:

1). Powder metallurgy method: select fine tungsten and copper powder, refined by first-class infiltration and sintering process, can withstand nearly 2000 ℃ and high stress, has high melting point, high hardness, anti-burning and good anti-adhesion, galvanic corrosion The product has high surface finish, high precision and low loss. The alloy is prepared by powder metallurgy method, which has good electrical and thermal conductivity, good high temperature strength and certain plasticity.

2). Mechanical alloying method: a method of sintering the tungsten-copper powder that has been processed by high-energy ball milling and has achieved mechanical alloying between tungsten and copper. On the one hand, it can reduce the particle size of the metal powder and promote the densification process; on the other hand, it can also cause the metal powder to produce severe lattice distortion, high-density defects and nano-scale fine structure, making the thermodynamic and kinetic characteristics of the powder system. With off-equilibrium properties, such as higher surface energy and surface activity, greater sintering driving force and better sintering performance, etc.
