CuNi30Fe1
Introduction to CuNi30Fe1 Copper Alloy
CuNi30Fe1, also known as Copper Nickel 30 Iron 1 (CuNi30Fe1), is a copper-based alloy that combines high strength, excellent corrosion resistance, and good mechanical properties. This alloy is particularly well-suited for applications that demand both strength and resistance to seawater corrosion, making it ideal for high-performance tooling, die casting components, and marine environments. The alloy's resistance to oxidation, wear, and fatigue makes it an excellent choice for die casting applications where durability and longevity are essential.
At Neway Die Casting, CuNi30Fe1 is used in high-performance tooling and casting components, particularly in aluminum and zinc die casting molds where enhanced corrosion resistance and mechanical strength are crucial.
