High strength copper gasket

Category: Copper thrust washer




High strength copper gasket, large copper gasket, corrosion-resistant copper gasket, wear-resistant copper gasket, environmentally friendly recyclable copper gasket. A high strength and wear-resistant copper alloy was prepared by mixing Al-Fe master alloy with excellent electrolytic copper as matrix according to the national standard. This copper alloy has high mechanical properties, good wear resistance and corrosion resistance, can be welded, not easy to braze, inSeven hundredAir cooling at (?) C can prevent brittleness. It is generally used in important castings with high strength, wear resistance and corrosion resistance.
