Most commonly used are Music Wire, Stainless Steel 302, Hard Drawn MB and Galvanized Hard Drawn. Other materials available are Stainless Steel Type 316 and 17-7 PH, Plated Music Wire, Oil Tempered, Beryllium Copper, Phosphorous Bronze, Inconel, Monel, Brass, Chrome Silicon and Chrome Vanadium and more high temperature and corrosion resistant alloys.
