Copper Nickel 969
- Exceptionally high strength and hardness
- A low coefficient of friction
- Great wear resistance
Copper Nickel 729 is a high strength Copper Nickel Tin Alloy cast, hot work heat treated to 930 MPA.
It is an exceptionally hard material with outstanding strength, high wear resistance, low friction and good machining properties. Copper Nickel 729 is regarded as the world’s best bearing material due to its unique physical properties and galling resistance. When used correctly it eliminates warranty bearing, increases reliability and increases load capacity.
Copper Nickel 729 is engineered to provide attributes beyond those typically found in high-strength copper alloys, especially in the high temperature, high pressure regime. Copper Nickel 729 material retains its strength at elevated temperatures and resists most sour environments. Some tempers of Copper Nickel 729 combine high levels of fracture toughness with strength.
