Hardness and toughness of tungsten copper alloy
The hardness of tungsten copper alloy is much higher than that of general copper alloy materials, and its hardness value can reach 300-400HB. This feature is mainly due to the inherent properties of tungsten.
Tungsten is a highly rigid metal with an extremely high melting point, which enables tungsten copper alloy to maintain its structural stability when subjected to high pressure and high temperature. Therefore, in application scenarios that require high strength and wear resistance, such as mold manufacturing and electrode production, tungsten copper alloy is highly favored due to its high hardness characteristics.
At the same time, tungsten copper alloy also exhibits good toughness. This is mainly due to the role of copper in the alloy, which balances the rigidity of the alloy, enabling it to withstand heavy load stress and high-speed cutting.
Tungsten copper alloys with different ratios, such as CuW75, CuW90, etc., also have different hardness performances due to their unique composition and preparation process, but all maintain good toughness.
