Johnson Matthey is the leading supplier of Precious Metal components for medical device applications.

Precious Metals

Precious Metals, in a large variety of alloy compositions, can be fabricated as tubing, rod, foil, sheet, ribbon, or wire to be incorporated into medical device products. Precious metals, particularly Platinum, are characterized by their high temperature melting points, radiopacity, resistance to corrosion, electrical conductivity and biocompatibility. As a result, Platinum and its alloys are finding increasing use in medical implant applications.

We use advanced melting, extrusion and wire and tube-drawing processes to provide a vertically-integrated process to solve our customer’s complex challenges. We offer the largest inventory, range of sizes and selection of alloys in the industry, and JM is your primary source for thin-walled precious metal tubing. Johnson Matthey is also the largest supplier of marker bands and ring electrodes used in implant applications requiring radiopaque metals.

Johnson Matthey is a long established producer of component parts and feedstock materials used by manufacturers in the medical device industry.  These parts include high quality precious metal tube, wire and micromachined components. The range of materials and size limits are detailed below. We make any size within the range specified to your individual requirements using classic deep drawing techniques employing tungsten carbide dies and steel mandrels.

Typical applications for our platinum and gold alloys include radiopaque marker bands, electrode tips, electrode rings, tip coils, pacemakers and defibrillators, and much more.
