Material Notes:
RWMA Class 11 and 12.Mi-Tech refractory alloys are manufactured by pressing, sintering, and infiltrating tungsten with copper or silver.Typical Resistance Welding Applications: Class 12 material is specifically recommended for heavy-duty or projection welding electrodes where the pressures involved are relatively high and for die facings in electro-forming and electro-forging applications. It is suitable as die material for electrical upsetting of non-ferrous metals and low carbon steel or for cross-wire welding of larger diameter wire and rod.Data provided by Mi-Tech Metals.
