Erosion Resistant Thust Washer For Automotive Applications

Thrust washer made of copper nickel tin alloys UNS C72900 Equal to thougmet

Inway such Cu15Ni8Sn is a direct equivalent to Toughmet 3 and is an ideal proven track record solution. Extensive testing ensures that Hardiall® is in full compliance with the relevant specifications: in that regard, using them can help high-end industries mitigate their supply chain risks.
Inway CuNi9Sn6 has been developed to master the technical, economic and ecological constraints for heavily load bearings in construction mining, automotive and industrial applications.
Inway is the ideal substitute for steels, casted leaded bronze or manganese bronzes as well as casted spinodal copper nickel tin alloys like C96900 CX105, C96970 CX90 ensuring the adequate fatigue strength.

Materials are available in two tempers:

• TX temper (wrought hot worked and spinodally hardened temper)
• TS temper (wrought hot worked, cold finished and spinodally hardened temper) offering the highest level of mechanical properties.

These Copper Nickel Tin spinodal alloys have a specific metallurgy enabling a spinodal decomposition and thus providing a unique combination of material properties.
High mechanical properties are reached by hot working or a combination of hot and cold working processing and are drastically enhanced with a final heat treatment controlling the spinodal decomposition.
For example, a threefold increase in the yield strength over the base metal is achieved after the spinodal decomposition treatment.
These heat treated "spinodal alloys" are a very good bearing and bushing materials due to their its high strength, low magnetic sensitivity, excellent machinability, maximum corrosion resistance
Additionally, their high surface resistance under impact loads and especially in critical lubrication conditions, when compared to conventional bearing materials it provides longer lifespan, higher reliability and better construction flexibility.
Hardiall® can be used under various environmental conditions, under high and very high loads at low and high speeds, lubricated, periodically lubricated or little 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 part of an ongoing qualification process in highly demanding industries such as Aerospace and Oil & Gas.
