Properties And Applications Of Tungsten Copper Alloy
Tungsten copper alloys are widely used in military, national defense, aerospace, aviation, navigation, electronic devices, medical equipment, and other fields due to their excellent physical and chemical properties. However, due to the large difference in physical and chemical properties between tungsten and copper, they cannot be produced by melting and casting, and powder metallurgy technology is generally used for production. In this article, let’s take a closer look at the properties and applications of tungsten copper alloy.

Properties and Applications of Tungsten Copper Alloy

Properties Of Tungsten Copper Alloy
Since tungsten and copper are two incompatible metals, copper-tungsten alloy combines the advantages of tungsten and copper, which is mainly manifested in its small volume expansion coefficient, good wear resistance and corrosion resistance, excellent electrical and thermal conductivity, and good high-temperature resistance.

Tungsten Copper Alloy Production Process
The process flow of preparing tungsten copper alloy by powder metallurgy: pulverizing→mixing of ingredients→press molding→sintering infiltration→cold processing.

Applications Of Tungsten Copper Alloy
1. Tungsten Copper Electrode
Tungsten Copper Electrode is suitable for use in welding electrodes due to its good high-temperature resistance, arc ablation resistance, high specific gravity, and easy machining.

2. Tungsten Copper Alloy Rod
It is a composite material refined through the process of static pressing, high-temperature sintering, and copper infiltration using the excellent metal properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder. It has the characteristics of good arc breaking performance, no softening at high temperature, high strength, and high hardness.

3. Tungsten Copper Electronic Packaging Sheet
It has both the low expansion characteristics of tungsten and the high thermal conductivity of copper. It is worth noting that the performance of the electronic packaging sheet can be changed by adjusting the ratio of the constituent materials.

4. Tungsten Copper Tube
It is widely used in cemented carbide and refractory metals. Because the tungsten-copper alloy is easy to machine, the use of tungsten-copper tube plays a great role when the surface needs to be easy to cut and the inner diameter is small.
5. Tungsten Copper Alloy Wire
Precautions for its use:

a. Colloidal graphite cannot be placed on the surface of tungsten copper wire.
b. When the temperature is above 1000 degrees, avoid putting tungsten copper wires with iron, nickel, and carbon together.
c. The tungsten copper wire must be placed in a dry place, and the relative humidity should not exceed 65% of the room temperature. Avoid placing it with acid or alkaline things.
6. Military High-Temperature Materials
Copper-tungsten alloys are used as nozzles, gas rudders, air rudders, and nose cones of missiles and rocket engines in aerospace.

The main requirements are high-temperature resistance (3000K~5000K) and high-temperature resistance to airflow erosion. The sweat cooling effect formed by the volatilization of copper at high temperature (copper melting point 1083℃) is mainly used to reduce the surface temperature of tungsten copper and ensure the use under extreme high-temperature conditions.
