CuNi2SiCr is a high-strength, beryllium-free copper alloy designed for applications where pure copper’s excellent thermal and electrical conductivity alone is not enough. While alloying elements typically reduce conductivity, the additions of nickel, silicon, and chromium in CuNi2SiCr deliver higher ultimate tensile strength and outstanding corrosion resistance, particularly against stress-corrosion cracking. This makes it ideal for pistons, electrodes, and wear or sliding components in demanding environments. Combining durability with efficient heat and electrical transfer, CuNi2SiCr ensures reliability in advanced manufacturing

• High strength
• Excellent corrosion resistance
• Good thermal and electrical conductivity

• Pistons
• Electrodes
• Wear and sliding components

Heat Exchanger

CuCr1Zr is Nikon SLM Solutions’ copper alloy with the lowest concentration of alloying elements and, therefore, brings an excellent balance of mechanical and conductive properties. With up to 92 % IACS after heat-treatment, CuCr1Zr still features very high electrical conductivities at up to 300 MPa ultimate tensile strength. Chromium and zirconium help to maintain both high strength and hardness at elevated temperatures – ideal for rocket engines.

• Highest electrical conductivity for SLM® copper alloys
• High temperature stability for strength and hardness
• Improved strength compared to pure copper
