75W25Cu Welding Electrode

Description                                     

The chemical composition of 75W25Cu tungsten-copper alloy principally consists of tungsten (W) and copper (Cu), wherein the tungsten content amounts to 75% and the copper content is 25%. Additionally, this alloy may incorporate a minor quantity of impurity elements like molybdenum (Mo), titanium (Ti), niobium (Nb), zirconium (Zr), etc. These elements contribute to enhancing the alloy's resistance to intergranular corrosion and carburization.

75W25Cu tungsten-copper alloy exhibits the following remarkable characteristics:

Exceptionally high hardness: Owing to the inherent high hardness of tungsten, the overall hardness of the alloy is considerably elevated.

Substantially high melting point: The elevated melting point of tungsten empowers the alloy to maintain its stability under high-temperature conditions.

Superior electrical and thermal conductivity: Thanks to the excellent electrical and thermal conductivity of copper, the alloy demonstrates outstanding performance in these regards.

Outstanding ablation resistance: It is ideally suited for applications that demand high ablation resistance, such as electrodes in high-voltage discharge tubes.

Impressive strength and density: The alloy possesses both high strength and high density, making it appropriate for application scenarios where these properties are crucial.
