Composite metal products feature two or more layers of precious metals or alloys metallurgically bonded to copper- or nickel-based alloys to yield such characteristics as biocompatibility, corrosion resistance, electrical conductivity, or low cost. The products are available as wire, rod, and bar stock, and in sizes from 0.002 to 1.500 inches OD. Standard products include titanium-clad copper, nickel-clad copper, platinum-clad anodes, and precious-metal-clad wire. Custom products can be designed to customer requirements.
