Tungsten Copper Types

Tungsten copper alloy have a variety of types, different types have different characteristics, so that it can be used in different products.

1. Tungsten copper electrical materials: Mainly divided into electrical contact and electrical processing materials.

1)Electrical contact material: It is one of the most important kinds of electrical materials with high resistance to arc erosion and welding resistance, as electrical contacts, electrical contacts and electrodes in instrument, applicable to all kinds of high and low voltage switchgear. The maximum amount of tungsten copper material containing 20% to 40%, electrical contacts is the largest class, the utility model is mainly used for medium, high voltage and high current switching devices.

2) Electrical material: Refers to the electrode and mold materials used in resistance welding, electric riveting and electric upsetting. Using more tungsten copper materials for meeting the requirements of EDM, ensure the machining accuracy.

2. Armor materials: Tungsten copper materials can be used as armor material, also known as liner. This type of liner was first made of red copper and was widely used. It should improve the penetration ability in order to increase the cover unit quality, Develop unit quality of tungsten cutting liner material which is larger than copper. In an ideal situation, it is about 30% higher than the penetration ability of copper. Use it to make a cup or funnel, inversion in the front end of a cartridge, depending on the temperature and pressure of the powder, the cover is changed to form a jet.

3. Instantaneous high temperature material: It can be used at temperature close to the melting point of tungsten and slightly above the melting point of tungsten, it is an important and special tungsten copper which can complete the mission in a few seconds to 200 seconds. The most important properties of the instantaneous high temperature materials are ablative and thermal shock resistance, this material is mainly used for the manufacture of high temperature components of spacecraft, such as the rocket nozzle, the direction of the guided missile and other components of the rudder. It has intense thermal shock damage to components.
