Product Description
Tungsten heavy alloys generally are two-phase composites consisting of W-Ni- Fe or W-Ni- Cu or even W-Ni-Cu-Fe. Tungsten content in conventional heavy alloys varies from 90 to 98 weight percent and is the reason for their high density (between 17 and 18.6 g/CC). Nickel, iron and copper serve as a binder matrix, which holds the brittle tungsten grains together and which makes the alloys ductile and easy to machine. Nickel-iron is the most popular additive, in a ratio of 7Ni: 3Fe or 8Ni: 2Fe (weight ratio). The conventional processing route for tungsten heavy alloys includes mixing the desired amount of elemental powders, followed by cold pressing and liquid phase sintering to almost full density.
Our high-Density tungsten heavy alloy production strictly follows the China aviation material standard and U. S. A. Aviation material standard. At present, we offer none-toxic, high density fishing fall, tungsten heavy alloy ball, round stick, golf head, off-centered dipole and other abnormal units. Production capacity: Above 200T/year. We are one of the few professional manufacturers of high density alloy in China.
