Copper Nickel Pipe fittings

What are copper nickel pipe fittings?

Applications that require above-par corrosion resistance and durability use these components. Copper nickel pipe fittings contain 70-90% copper and 10-30% ni with other elements like iron and manganese.

Copper nickel buttweld fittings are well-suited to marine environments and frequently work in shipbuilding, offshore navy projects, and desalination.
