Explore copper alloys designed for high-performance applications requiring excellent mechanical and conductive properties. CuNi30 offers improved strength over pure copper and exceptional resistance to seawater corrosion, including pitting, stress corrosion cracking, and biofouling. Although its electrical conductivity is lower than pure copper, it provides an excellent balance of durability and weldability, making it ideal for heat exchangers, marine piping, condensers, and offshore components exposed to high temperatures and pressure. CuNi2SiCr is a thermally hardenable alloy with enhanced stiffness at elevated temperatures while retaining strong electrical and thermal conductivity—well suited for toolmaking, conductive contacts, and valves. CuCr1Zr combines high electrical conductivity (up to 92% IACS after heat treatment) with strong mechanical performance, making it a reliable choice for demanding applications such as rocket engines.
CuNi30 offers good strength and excellent corrosion resistance, especially in seawater. It resists pitting, stress corrosion cracking, and biofouling, making it a preferred material for heat exchangers, marine piping, condensers, and offshore structures or components. Although its electrical conductivity is lower than pure copper, CuNi30 provides an excellent balance of mechanical strength, durability, and weldability. The alloy remains stable under high temperatures and pressure, ensuring long service life, and its corrosion performance is best maintained by minimizing oxygen contamination during processing. Robust, reliable, and widely validated in marine engineering, CuNi30 is a proven choice for demanding industrial environments.
Material characteristicsCuNi2SiCr 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

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.
