Chemical Vapor Deposition CVD Tungsten Products Semiconductor Tungsten Ring
Tungsten Rings can be customized in width, thickness and ring diameter. Tungsten Rings can have a custom shaped hole and can be open or closed. American Elements specializes in producing high purity, uniformly shaped Tungsten Rings. We offer custom rings with annealed or hard temper and will meet most common Milspec or ASTM standards. Tungsten Rings are hollow, circular pieces of metal and can be produced in custom sizes. In addition to standard alloys, we specialize in corrosion resistant alloys, high temperature applications, and custom shapes and forms, including custom inner and outer dimensions and threads. American Elements also produces tungsten as rods, ingots, powder, pieces, discs, granules, wire, and in compound forms such as oxide. Tungsten rings can be used as components in a variety of applications.
