Introduction to Tungsten-Copper Alloy

Tungsten-copper alloy is a metallic material composed of tungsten and copper. It possesses excellent physical properties and chemical stability. Its chemical composition mainly consists of tungsten (W) and copper (Cu), with the content of tungsten typically ranging from 60% to 90%, and the content of copper being between 10% and 40%. Besides tungsten and copper, tungsten-copper alloys may also contain small amounts of other elements, such as nickel, iron, silver, etc., to improve their performance.

Main Chemical Components and Functions

1. Tungsten (W): Tungsten is the main component in tungsten-copper alloys, featuring high melting point, high density, and high hardness. The addition of tungsten can enhance the alloy's high-temperature resistance, strength, and wear resistance, making it suitable for applications in harsh environments such as high temperatures and high pressures.

2. Copper (Cu): Copper is another important component in tungsten-copper alloys, with excellent electrical and thermal conductivity. The addition of copper can improve the processing performance of the alloy, lower its melting point, and increase its toughness at low temperatures. Additionally, copper can form a solid solution with tungsten, enhancing the overall performance of the alloy.

Chemical Composition and Performance Relationship

The chemical composition of tungsten-copper alloys has a significant impact on their performance. Generally speaking, as the tungsten content increases, the hardness, strength, and high-temperature resistance of the alloy will improve, but the electrical conductivity and thermal conductivity will decrease. Therefore, in practical applications, it is necessary to select the appropriate tungsten-copper alloy composition based on specific requirements to achieve the best performance balance.

Applications of Tungsten-Copper Alloy

Tungsten-copper alloy possesses high specific strength, high thermal conductivity and excellent wear resistance, thus being widely used in the following fields:

1. Equipment Manufacturing: Tungsten-copper alloy is extensively applied in high-temperature and high-pressure fields such as aviation, aerospace, military industry, and chemical industry, mainly used for manufacturing aircraft engines, turbine blades, high-temperature and high-pressure valves and other mechanical equipment.

2. Electrical Equipment: Tungsten-copper alloy has excellent electrical conductivity and wear resistance, and is thus widely used in electrical equipment such as electrodes, circuit breakers, contacts, and brushes.

3. Mold Manufacturing: Tungsten-copper alloy has high hardness and strong wear resistance, and is thus widely used in mold manufacturing, such as injection molds, blow molds, and extrusion molds.
