Tungsten Copper Military Block

Tungsten copper military block has low CTE, high soften temperature, which not only plays an important part in electrical materials, but also has been widely used in high temperature material and military armor material. The most outstanding characteristic is that copper evaporating takes away a part of heat and keep it working stable; in military field, for some missile, penetrator and liner, tungsten copper material remarkably improves armor capability. 

Application

1. Used as EDM electrode, is easy for cutting and has sweat cooling, anti-adhesion, which is suitable for butt welding and projection welding with high requirement of wear resistance and high temperature resistance;

2. It can be widely used in high temperature material, electrical alloy for high-voltage switch, micro-electronics material;

3. Used in vacuum electrical contact, transformer switch contact and some electric upsetting electric forging industry and its good machinability processed into a variety of shapes of the W-Cu contacts as well as a variety of infiltration, casting material;

4. It provides a good solution for the deformation in small precision electrode machining;

5. Used as high temperature components of rocket, missile with high-speed airflow ablation, such as gas vane, nozzle, throat insert, nose con and so on;

6. In the 1990s, copper tungsten material has already begun used as new electronic package and the heat sink material. And it gradually appears in CPU, large-scale integrated circuit, high-power micro-wave device, connection and radiating component.

Tungsten Copper Machining

The method of tungsten copper machining is mainly divided into two categories: infiltration and direct sintering method. In recent years, due to the rapid development of nanotechnology, directly obtained by sintering a great development.The melting point of tungsten, copper vary greatly higher than the boiling point of the copper melting point of tungsten and tungsten copper immiscible, the general method of smelting is difficult to produce tungsten copper alloy, the only powder metallurgy to make tungsten copper composites manufacturing to become a reality.

Tungsten copper machining include the following methods:
Infiltration Method
High Temperature Sintered Tungsten Copper Alloy
Mixed Powder Sintered Copper Infiltration Method
Direct Sintering Method

Our general method is infiltration, the infiltrated divided into high temperature sintered tungsten skeleton copper infiltration and low-temperature sintering mixed powder copper infiltration two.

The following is the picture about our tungsten copper product with which is used infiltration method:

10±2	0.5	Balance	16.75	6.5	27	2550	11

Tungsten copper content is the content of tungsten or copper in the alloy, the normally content for tungsten copper alloy is 10%～50%. Tungsten copper alloy powder metallurgy extraction has good electrical and thermal conductivity, good high temperature strength and a certain degree of plasticity. At very high temperatures, such as above 3000 ℃, copper alloy is liquefied evaporated absorbs heat, reduces the surface temperature of the material. So this kind of material is also referred to as metal sweating material.
