New type copper alloys have great mechanical properties, wear resistance, corrosion resistance, and exceptional electric/thermal conductivity.
The “non-sparking alloys” designed by SAMC do not contain the highly toxic element beryllium and have more competitive prices. The hardness of the alloys can reach as high as HRC 38 after optimal heat treatment procedure. The non-sparking property makes the alloys excellent candidates for equipment parts or hand tools used in flammable environments such as factories with fine dust. The high hardness, wear resistance, and excellent electric/thermal conductivity also make the non-sparking alloys suitable for semiconductor probes to replace the traditionally used, expensive, and toxic beryllium copper alloys.
The “self-lubricating alloys” developed by SAMC can reach the hardness value of HRC 30 after optimal heat treatment process, and they can serve as the worm screws and wheels in the fourth axis of machine tools. Compared to conventional copper alloys, the great wear resistance of our self-lubricating alloys can effectively extend the service life of machine parts.
