Wiraphan Sheets and Plates, a reputable manufacturer and supplier based in Bangkok, Thailand, is well-known for its high-quality Copper Nickel Coils and Slitting Coils. The company focuses on providing copper-nickel alloy products that adhere to international standards for corrosion resistance, strength, and durability. These copper-nickel coils are particularly effective against seawater, biofouling, and oxidizing environments, making them perfect for marine, chemical, and industrial applications. Wiraphan offers these coils in a variety of widths and thicknesses, ensuring precision-cut, ready-to-use materials for industries that demand long-lasting and high-performance copper-nickel solutions.
Copper Nickel Coils and Slitting Coils primarily consist of copper (the balance) and nickel (10–30%, depending on the grade), with trace amounts of iron and manganese to boost strength and corrosion resistance. This specific alloy composition provides remarkable resistance to seawater, oxidizing conditions, and stress corrosion cracking, all while maintaining good thermal and electrical conductivity. In terms of mechanical properties, these coils boast a tensile strength of 270–400 MPa, a yield strength of around 150–250 MPa, and impressive elongation, ensuring reliable performance during rolling, forming, and fabrication processes.
