Press copper wire master, high strength copper wire master, corrosion-resistant copper wire master, wear-resistant copper wire master, environmentally friendly recyclable copper wire master. 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.
