CuNi2Si Material Properties:

Hard copper alloy with high thermal conductivity and high mechanical properties combined with good hardness and high temperature strength. Good resistance to tempering. Nitriding and case-hardening are not suitable.

CuNi2Si Areas of Application:

Spot welding electrodes and seam welding discs for stainless steel, Monel and nickel alloys

• Flash welding dies, wire mesh electrodes
• Plastic blow and injection moulds and inserts in steel tools for higher cooling rates
• Nozzles and needles for hot runner systems
• Plunger tips in aluminium die casting machines
• Moulds for non-ferrous metal castings (as copper, brass, bronze)
• Welding tools in plastic packaging
