Product Description

Tungsten alloy paperweight
Tungsten alloy paperweight is a tool used to press paper when writing and painting, made of tungsten alloy. Since the establishment of paperweight, it has been over 1500 years. In the early days, bronze and jade were used as materials for paperweight, and later stone, rosewood, and ebony also joined the ranks of paperweight.
Tungsten alloy paper has a high hardness (10 times harder than 18K gold and 4 times harder than titanium); Good tensile strength, not easily deformed; Stable chemical properties and corrosion resistance; High density, with radiation shielding effects and other characteristics. Tungsten alloy paperweights are polished with diamond tools, with exquisite craftsmanship and exquisite products.

Xi'an Kefeng Powder Metallurgy Co., Ltd: Tungsten alloy paperweight is one of our products, which is made by a metal compression molding process. It has good physical and chemical properties. W-Ni-Fe alloy, It mainly contains (93-95)% tungsten, the density can reach 17.25-17.85g/cc. Nickel and iron act as a binder between tungsten particles, making the material malleable and workable. W-Ni-Fe has better mechanical properties and is widely used in the national defense industry.
