Rulon Bearings
Mi-Tech Metals HD18 Tungsten-Based Metal
Categories: Metal; Nonferrous Metal; Refractory Metal; Tungsten Alloy

Material Notes: Mil Spec T-21014D Class 3; ASTM B-777-99 Class 3; ASTM B-777-07 Class 3; AMS T-21014 Class 3. Nil magnetic properties.

Manufactured by powder metallurgy methods. The tungsten base offers high thermal conductivity and a low CTE which combine to resist thermal fatigue. The high melting point reduces soldering or erosion problems. To increase the machinability of this brittle metal, alloying elements are added and practical use of tungsten is possible for die casting tools.

Used in resistance brazing and high temp applications. Used as counter weights and counter balances, radiation shielding components, tool shanks for boring bars and other tools for chatter-free machining.
