copper nickel 90/10 tube copper nickel alloy tube, copper tube copper Nickle Tube copper nickel tube manufacturers
seamless copper nickel tube
1.Use:Evaporator,Heat Exchanger,Condenser,Distiller
2.ISO9001/14001/18001
3.ASTMB111/EN12451/BS2871.
The seamless copper nickel pipe/tube C71500 which is widely used for Evaporator,Heat Exchanger,Condenser,Distiller.
under standard ASTM B111, we can provide alloy tube C71500, C70600, C71640, etc.
advantage of C71500 copper nickel tube
high erosion and corrosion resistance.
very high weld ability,
easy for installation
high antifouling properties against sea microorganisms.
Relatively high iron content provides better impingement attack resistance.
The alloy is unique to stress corrosion cracking. This form of copper alloy gives the best service life under the most adverse conditions.
