High strength copper nut, corrosion resistant copper nut, wear resistant copper nut, environmental friendly recoverable copper nut. 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.
