Tungsten aluminum alloys have excellent properties of both aluminium and tungsten, such as low density, high specific strength, high temperature resistance, corrosion resistance and easy processing. In addition to the advantages of aluminium and tungsten, aluminium-tungsten alloy also has the greatest feature of wear resistance, which can be well applied to golf clubs and ball heads, medical equipment components (breathing machines), automotive engine piston, hub and other components, and hopefully in the future to be applied to armor materials and aerospace engines and other fields.

The front and rear casings of the aero-engine compressor are made of iron-based and nickel-based alloys respectively. During the process of use, the butt joints of the front and rear casings are in vibration and are prone to impact wear. The original wear-resistant coatings are due to hardness. The lower the toughness, the more damage occurs after a period of wear, and the life of the front and rear casings is shortened. Therefore, it is an urgent problem to prepare a coating with high wear resistance to solve the wear of aviation equipment and prolong the service life of aviation equipment.

In recent years, with the development of low-voltage electrical industry, various series of new circuit breakers have been introduced. These new circuit breakers require contact materials with smaller volume and higher breaking capacity. At present, the matching of AgWC12C3 and AgW50 is often used as asymmetrical and reasonable matching contacts of circuit breakers in AgWC-C electrical contact materials, so as to improve the arc resistance and material transfer resistance of AgWC-graphite electrical contact materials, which is the necessary condition for expanding the application range of AgWC-graphite contact materials and meeting the increasingly stringent performance requirements of circuit breakers for contact materials.
