Product Description

High Strength Polished Tungsten Heavy Alloy Blocks

Tungsten Heavy Alloy Blocks are mainly divided into two series of W nickel iron and W nickel copper, and even W nickel iron copper. In contrast, West Nickel-Fe 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 has gradually expanded to various civilian industries.

Introduction & Features of Tungsten Heavy Alloy Blocks

High density: the density of tungsten alloy can reach 18.5g/cm3, and the volume is much smaller than other materials under the same mass.
Corrosion resistance: The chemical properties of tungsten alloys are stable and do not react with any substances at room temperature. Fishing pendants are used for long-term contact with water. If it is iron material, it is easy to be oxidized.
High hardness: The hardness of tungsten alloy is second only to that of diamond, and it has considerable hardness. The fishing pendant will inevitably collide with hard objects during use. The high hardness material can make the spreader not easy to break and deform.

Application of Tungsten Heavy Alloy Blocks

The weight in the automatic watch uses the slight movement of the arm and the inertia of the weight to drive the winding, in order to achieve the purpose of automatic winding. The greater the gravity of the hammer, the greater the inertia energy and the longer the travel time. Therefore, the hammer material needs to have sufficient gravity, non-magnetic, moderate strength and good corrosion resistance, and can be machined into another precision part. At present, some famous Brands of Swiss automatic watches use this alloy, most of which are W-NICU alloy. When in use, gold or nickel plating should be applied to the surface of the hammer parts to improve corrosion resistance and aesthetics. China has also adopted high gravity tungsten alloy as the weight material for automatic watches.
