The physical properties of tungsten plate
Tungsten plate is gray or silver white, it has high hardness and high melting point. At room temperature it is not affected by air erosion. The main purpose of tungsten plate is to manufacture the filament, high speed cutting alloy steel and ultra hard mold, it is also used in optical instruments, chemical equipment. China is the largest country that store the tungsten in the world.
Tungsten is a kind of metal element. It is hard and brittle silver white crystal. It has high melting point and can be made into very thin wire and special alloy steel. Tungsten belongs to nonferrous metal and it is also an important strategic metal. Tungsten ore is known as "heavy stone" in ancient times. In 1781, Swedish chemist Carl Wilhelm Scheele discovered the scheelite, and extract the elements of new acid- tungstate. In 1783, the tungstate is also found by Spaniard Depp Aria from wolframite. In the same year, the carbon reduced tungsten trioxide to get tungsten powder, and named this element. The content of tungsten in the crust accounts for 0.001 percent. Twenty kinds of tungsten minerals have been found. Tungsten deposits are generally formed by the activities of granitic magma. After smelting, the tungsten is a kind of shiny metal, which has high melting point and high hardness. Tungsten has the highest melting point.
