NS30 | CuNi7Si2Cr key properties 

NS30 | CuNi7Si2Cr is a nickel‑silicon-bronze alloy engineered for applications requiring a combination of high thermal dissipation and high mechanical strength. Non‑sparking by nature and resistant to corrosion, NS30 is particularly suited for components operating under demanding thermal and mechanical conditions. Its balanced properties make it suitable for both industrial and automotive environments where safety and reliability are essential. 

NS30 | CuNi7Si2Cr exhibits high thermal conductivity, excellent wear and galling resistance, and good impact and fatigue performance, ensuring reliable behavior under repeated mechanical and thermal loading. The alloy also offers good corrosion resistance, low magnetic permeability and stable dimensional behavior, maintaining its properties at temperatures up to 350 °C. Suitable for processes such as extrusion, forging and die stamping, NS30 enables the production of complex components requiring both strength and thermal performance. 

As a nickel‑silicon bronze alloy, NS30 delivers a balanced combination of thermal conductivity, mechanical strength and durability, making it a dependable solution for components operating in demanding industrial environments.
