Specialty Metals and Alloys

MWS "Specialty Metals" cover a broad range of materials from high purity precious metals to high temperature refractory metals. When alloyed, these metals combine to create hundreds of materials with many unique physical, thermal, and electrical properties. Most of the metals and alloys shown below are available in wire, ribbon, foil, square and rectangular shapes.
