Spring wire coatings
A Complete Selection of Options
Central Wire produces a full line of economical and cost saving coatings for stainless steel and corrosion resistance nickel alloy spring wires. Central Wire’s soap and nickel flash coatings enable a higher level of productivity. Wire produced with a specialty coating exhibits excellent coilability at high speeds and often requires no additional lubricant during manufacture. Coatings on spring wires reduce the stress on coiling equipment, extending equipment life and minimizing down time. Whether you need a nickel flash coating, or a copper with soap coating, CWI has you covered.
Central Wire’s specialty coatings also enhance the look and performance of stainless steel and corrosion resistant nickel alloy springs. They have proven to enhance corrosion resistance and maintain a bright, finished look over extended periods.
