Erosion Resistant Thust Washer For Automotive Applications

Thrust washer manufactured from 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 for demanding applications.

Extensive testing ensures that Hardiall® is in full compliance 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.

Inway 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.

Materials are available in two tempers:

These Copper Nickel Tin spinodal alloys feature specific metallurgy enabling spinodal decomposition, providing a unique combination of material properties. High mechanical properties are achieved through hot working or a combination of hot and cold working processing, drastically enhanced with a final heat treatment controlling the spinodal decomposition.

For example, a threefold increase in yield strength over the base metal is achieved after spinodal decomposition treatment. These heat-treated "spinodal alloys" are excellent bearing and bushing materials due to their high strength, low magnetic sensitivity, excellent machinability, and maximum corrosion resistance.

Additionally, their high surface resistance under impact loads and in critical lubrication conditions provides longer lifespan, higher reliability, and better construction flexibility compared to conventional bearing materials.

Hardiall® can be used under various environmental conditions, under high and very high loads at low and high speeds, lubricated, periodically lubricated or with minimal lubrication in the temperature range from -125°C to +300°C in combination with different materials.

These materials have already been approved by numerous OEMs or are compliant parts of ongoing qualification processes in highly demanding industries such as Aerospace and Oil & Gas.
