Cuptin® (CuSn) is an alloy of copper and tin, known for its high strength, wear resistance, and weldability properties, making it widely used in various industrial applications. This material is commonly used in high-performance engineering applications such as bearings, sliding bearings, gears, and valves. Cuptin® (CuSn) shows excellent wear resistance due to its ability to withstand high surface pressures, making it particularly suitable for applications with high-speed rotations. Additionally, it is resistant to high temperatures and corrosion, making it suitable for challenging environments. Cuptin® (CuSn) can be a sought-after material for high-performance and long-lasting applications in various industrial sectors. When compared to Cupral series aluminum bronzes, Cuptin® 4M has superior mechanical properties compared to the Cuptin® series tin bronzes. The only area where tin bronzes are advantageous is linear and radial bearings operating at speeds above 1500 rpm. They have better lubricating properties at high speeds compared to aluminum bronzes.
