High Strength Polished Tungsten Heavy Alloy Blank 90WNiCu

Tungsten Heavy Alloy Blank is mainly divided into tungsten nickel-iron, tungsten nickel-copper and even tungsten nickel-iron copper. In contrast, West nickel-iron alloy has better mechanical properties and plays an important role in the defense industry and various sectors of the national economy. It is a very important new military material in the national defense industry and is gradually developing into various civil industries.


Introduction & Features of Tungsten Heavy Alloy Blank

  1. High density: Tungsten alloys have a density of 18.5g/cm3 and are much smaller than other materials of the same mass.

  2. Corrosion resistance: Tungsten alloys are chemically stable and will not react with anything at room temperature. Fishing pendants are used for prolonged exposure to water. If the material is iron, it is easy to oxidize.

  3. High hardness: Tungsten alloy hardness is second only to diamond, with considerable hardness. Fishing pendants inevitably collide with hard objects during use. High hardness materials make the spindles less prone to fracture and deformation.

Application of Tungsten Heavy Alloy Blank

  • The weight in the automatic watch uses the slight movement of the arm and the inertia of the weight to drive the windings for automatic winding. The heavier the hammer, the greater the inertial energy, and the longer it takes to move. Therefore, hammerhead materials need to have sufficient gravity, non-magnetic, moderate strength and good corrosion resistance, and can be machined into other precision parts. At present, some famous Brands of Swiss automatic watches use this alloy, most of which are W-NICU alloy. When using, the hammer should be plated with gold or nickel to improve corrosion resistance and beauty. China has also adopted high gravity tungsten alloy as a counterweight material for automatic watches.
