Customized On Demand Buking Bar For Maching Tungsten Alloy With Precise Size

Description:

   The density of tungsten is 19.35 g/cm3, close to gold, with a melting point of 3422°C and a boiling point of 5927°C. Tungsten is a silvery-white metal, resembling steel in appearance, with the highest melting point of all metallic elements and a slow evaporation rate. Tungsten is chemically stable, does not react with air and water at room temperature, does not react with any concentration of hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, but can be quickly dissolved in a mixture of hydrofluoric acid and concentrated nitric acid acid, and does not work in alkaline solutions.

  Tungsten is widely used in alloys, electronics, and chemicals because of its high melting point, high hardness, high density, good electrical and thermal conductivity, and low coefficient of expansion.Therefore, the bulking bar made of tungsten is corrosion-resistant, high- temperature- resistant, and durable for a long service life.

^A When specified by the purchaser, other hardness testing methods may be employed.

B For mechancially worked or aged material, the hardness can be as high as R_c46.

A ^{Determine with an extensometer accurate to 0.5% elongation or class.}

^{B Nonmagnetic composition to Classes 1,2and 3 shall be 94 ksi(648 MPa) miinimum ultimate tensile strength . Minimum alongation shall be 2% on Classes 1 and 2 and 1% on Class 3.}
