What is a C70600 copper nickel tube?
C70600 is a copper-nickel alloy material, also known as white copper. The material is composed of 90% copper and 10% nickel. It has good electrical conductivity and strength, as well as good cold and hot processing properties and welding properties. This material is commonly used to make ship parts, condenser tube sheets, strips and sheets for weatherstripping, etc.
Key Applications
Power Plant Heat Exchangers
Desalination Systems
Petrochemical Facilities
