- noun a hard, malleable, greyish-white element used in lamp filaments, electrical contact points and, alloyed with steel, in high-speed cutting tools
- A lustrous silver-gray metal whose atomic number is 74. It is very hard, dense, ductile, has great corrosion resistance, and has the highest melting point and lowest vapor pressure of all known metals. At elevated temperatures it also has the highest tensile strength. It has almost 35 known isotopes, of which 3 are stable. Its applications include its use as lamp filaments, in electron tubes, in X-ray tubes, hard parts such as rocket nozzles, and in high-speed cutting devices and tools. Also called wolfram, from where it gets its chemical symbol, W.
