Characteristics and applications
Aluminum bronze copper nut, high strength copper nut, corrosion-resistant copper nut, wear-resistant copper nut, environmentally friendly recyclable copper nut. The high strength wear-resistant copper alloy is formed by using excellent electrolytic copper as the matrix and adding aluminum iron intermediate alloy according to the national standard ratio. This copper alloy has high mechanical properties, good wear resistance and corrosion resistance, can be welded, not easy to braze, air cooling at 700 ° C can prevent brittling, generally used in important castings requiring high strength, wear resistance and corrosion resistance.
