CuNi 70/30 20μm-63μm
CuNi 70/30 copper alloy offers a unique combination of corrosion resistance, thermal stability, electrical conductivity, mechanical strength, and antimicrobial properties, making it a versatile material for advanced manufacturing across various industries. One of the primary reasons CuNi 70/30 is used is its exceptional resistance to corrosion in seawater, brackish water, and various chemical environments. CuNi 70/30 also offers good mechanical strength, allowing it to withstand mechanical stresses and pressures in piping systems, fittings, and valves.
The 20-63 µm particle size suggests good spreadability for recoating systems with recoat speeds up to 260 mm/s. Other tailored particle size distributions are available upon request.
