Specializing in the supply of Grade UNS R30035 Alloy Sheet raw materials and processing. We provide high-quality alloys, stainless steel, and metal development solutions.
We are suppliers of Cobalt Chrome Molybdenum (UNS R30035 Alloy Sheet), a cobalt-chromium-molybdenum (Co-Cr-Mo) alloy used for machining and forging stock, especially in the medical implant industry. The molybdenum improves strength and heat resistance, while the chromium provides oxidation and corrosion resistance. This material is highly biocompatible, making it ideal for surgical implants such as knee, hip, and shoulder replacements.
UNS R30035 Alloy Sheet is primarily used in medical manufacturing where high fatigue life is required for repeated movements in joints.
