Pure tungsten is a high-performance material with a high melting temperature, high density, low vapor pressure, and low thermal expansion properties. It also offers good thermal conductivity, sufficient electrical resistance, and a high modulus of elasticity.
Marketech offers pure tungsten sheets and discs with alkali washed or ground finishes. Our tungsten sheets/discs are available in thicknesses from 0.1 to 15 mm, and sizes up to 450 x 1000 mm, depending on thickness.
Pure tungsten bar and rod stock are available with ground surfaces and can be sintered or swaged. Diameters range from 1 to 30 mm in diameter and up to 2,000 mm long, depending on desired size and conditioning. Large ranges of custom crucibles and single crystal ingots are also available.
