The difference between high gravity alloy and cemented carbide

Although high-gravity alloy and tungsten carbide are an alloy product of transition metal tungsten, they can be applied to aerospace, navigation and other fields, but due to the different addition elements, composition ratio, production process, the performance and use of the two are also very different.

High specific gravity alloy, also known as tungsten alloy, is an alloy with tungsten powder as the main raw material, nickel, iron, copper and other elements as auxiliary materials. Tungsten content is generally between 85% and 99%. Tungsten carbide, also known as tungsten steel, is an alloy with refractory metal carbides such as tungsten carbide as the main component, and elements such as cobalt, nickel and molybdenum as the binder. Binder content is generally between 10% and 20%. Cemented carbide has similar properties to tungsten alloy.

The difference between high gravity alloy and carbide is the difference in density and strength. High-gravity alloys have a much higher density than carbide, so their mass and strength are also higher than carbide. However, cemented carbide has brittleness and high hardness, which makes cemented carbide difficult to process and requires special processes to process. In contrast, high-gravity tungsten alloys are easier to process. Tungsten alloy is widely used in shielding parts, crankshaft, counterweight parts and other industries.
