Product Description

CuNi15Sn8: UNS C72900; ASTM B505. CW355H EN 12163 tempers Y760 R1100 R1130
CuNi15Sn8 complies with and exceeds the aerospace standards (AMS 4596, 4597, 4598, UT AMS 2154 class B…) as well as Oil & Gas customers specifications including NACE MR0175 corrosion and UT API-6A paragraph 7.4.2.3.17. controls.
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.
