2022 wholesale price Moly Filler Rod - Tungsten copper alloy rods bars supplier – WINNERS Detail:
Product Description
Tungsten copper alloy combines the advantages of copper and tungsten, high strength, high specific gravity, high temperature resistance, arc ablation resistance, good electrical conductivity, good processing performance. High-quality tungsten powder and oxygen-free copper powder are used, and isostatic pressing (high temperature sintering-copper infiltration) is used to ensure product purity and accurate ratio, fine structure and excellent performance. Good arc breaking performance, good electrical conductivity, good thermal conductivity and small thermal expansion.
