Product Description
Harmless Self Lubricating Bearings Copper Nickel Tin Alloys
Spinodal Cup made of copper nickel tin alloys UNS C72900, equivalent to Toughmet. Inway Cu15Ni8Sn is a direct equivalent to Toughmet 3 and provides a proven track record solution. Extensive testing ensures that Hardiall® fully complies with relevant specifications, helping high-end industries mitigate supply chain risks.
Inway CuNi9Sn6 has been developed to master technical, economic and ecological constraints for heavily loaded bearings in construction mining, automotive and industrial applications. It serves as an ideal substitute for steels, casted leaded bronze or manganese bronzes, as well as casted spinodal copper nickel tin alloys like C96900 CX105 and C96970 CX90, ensuring adequate fatigue strength.
