Refractory Metals
by liquid-phase sintering of compacts of tungsten powder with binders of nickel-copper, iron-nickel, iron-copper, or nickel-cobalt-molybdenum combinations; tungsten usually comprises 85 to 95% of the alloy by weight. These alloys are often identified as heavy metals or machinable tungsten alloys

Metal-Matrix Composites
, are obtained from the commercial abrasives industry. Silicon carbide particulates are also produced as a by-product of the process used to make whiskers of this material. A number of metal wires including tungsten, beryllium, titanium, and molybdenum have been used to reinforce metal matrices. Currently

Guidelines for Selecting the Right Brazing Alloy
copper and its alloys, this alloy group may also be used on silver, tungsten and molybdenum. Copper phosphorous alloys are not used on ferrous or nickel-containing alloys because iron and nickel form glass-like compounds with phosphorous, and the joints produced may be brittle. Silver - Copper

Tungsten
, iron-nickel, iron-copper, or nickel-cobalt-molybdenum binders. In compact forms, these tungsten alloys can be machined by turning, drilling, boring, milling, and shaping; however, they cannot be wrought at any temperature and therefore are not available in mill forms. Heavy tungsten alloys can
