Tungsten alloy is also called high specific gravity tungsten alloy, which is generally produced by powder metallurgy process using WNiFe, WNiCu or WNiCuFe. There are certain differences in the content of medium tungsten alloy according to the different use of products and the requirements of the use environment. Adding rare metal elements (Co, Mo, Cr, etc.) can improve some properties of the product, such as: hardness, ultimate tensile strength, yield strength, elongation, etc.
Paperweight is a traditional Chinese study utensil with a very long history. The most important function is to suppress the paper so that it will not be blown away or wrinkled. It is easy to write and has a beautiful effect. Therefore, it is generally used as a paperweight. There is a certain weight, such as bronze ware, jade ware, etc., and the shapes are various for appreciation. Until now, many artists who love to write with calligraphy will also use paperweights to press books and paper.
Due to the unique characteristics of tungsten alloy, tungsten alloy block paperweight has high hardness, which ensures long-term beauty and never fades. The surface of the tungsten alloy block paperweight is polished, it will last longer than other metals and will not deform.
