C71500 Cupronickel

C71500 white copper
Standard: ASTM b111m-1992, b122-1990, b151m-19889, b466m-1986 (1992, 1993 edition)
Name: 70-30 copper nickel alloy
● characteristics and application:
The properties and uses of c71500 white copper are the same as those of c70600, with good cold and hot workability. C71500 white copper is mainly used as condenser tube, vaporizer tube and heat exchanger sleeve.
● chemical composition:
Copper + alloy element Cu: ≥ 99.5
Copper + silver Cu + Ag: ≤ 65.5
Lead Pb: ≤ 0.05 ①
Iron (FE): 0.40 ~ 1.0
Zinc Zn: ≤ 1.0 ①
Nickel (Ni): 29.0 ~ 33.0
Manganese Mn: ≤ 1.0
Other elements: ①
Note: ① when the product is used for welding and the ordering party puts forward requirements, Zn content shall not be greater than 0.50%, Pb shall not be greater than 0.02%, P ≠ 0.02%, C ≠ 0.05%
Use: white copper is a copper based alloy with nickel as the main additive element. It is characterized by good mechanical properties and corrosion resistance, silver white, and metallic luster,
