Tungsten Foil & Tungsten Strip(W Foil,W Strip)

Product Code : ME-W-99.999%-SF

Tungsten foil is a thin slice of tungsten, with a purity greater than 99.9%, a thickness of 0.05~0.5mm, a width of 5~400mm and a length of 50~1500mm. Its surface states include alkali pickling surface, annealing surface and polished surface.  The surface states include alkali pickling surface, annealed surface and polished surface. From the perspective of physical and chemical properties, tungsten foil is a kind of silver-gray metal sheet with metallic luster. The melting point is about 3410℃, the boiling point is about 5660 ℃, and the relative density is 19.35g/cm3

Product Information

Tungsten foil is a thin slice of tungsten, with a purity greater than 99.95%, a thickness of 0.05~0.3mm, a width of 100~400mm and a length of 400~1500mm. Its surface states include alkali pickling surface, annealing surface and polished surface. Tungsten foil is a thin slice of tungsten with a purity greater than 99.95%, thickness of 0.05-0.5mm, width of 5-400mm and length of 50-1500mm. The surface states include alkali pickling surface, annealed surface and polished surface. From the perspective of physical and chemical properties, tungsten foil is a kind of silver-gray metal sheet with metallic luster. The melting point is about 3410℃, the boiling point is about 5660 ℃, and the relative density is 19.35g/cm3

It has the characteristics of low vapor pressure, low evaporation rate, low plastic brittleness transition temperature, low resistivity, good chemical stability, creep resistance, heat resistance and toughness. At room temperature and pressure, it will not react with air, water, concentrated hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid and aqua regia and other substances, but will dissolve in the mixture of hydrofluoric acid and concentrated nitric acid. In addition, under heating conditions, it will react weakly with concentrated hydrochloric acid, sulfuric acid, nitric acid and other inorganic acids (except hydrofluoric acid).
