Tungsten steel is a kind of sintered composite cemented carbide material, it’s also known as tungsten titanium alloy, which contains at least one kind of metal carbides. Because of its high wear resistance, heat resistance, corrosion resistance and high hardness, tungsten steel has the very broad range of applications in industry, such as the cutting tool in machining, so tungsten steel can also be called as the teeth of modern industry. In addition, the properties of high hardness, uneasy deformation and discoloration make the tungsten steel be made into all kinds of jewelry, which is very popular. Since tungsten steel’s hardness can reach to 8.9~9.1 Mohs, so compared with the jewelry making process with the other materials, tungsten steel jewelry machining process is more complex and more difficult.

 

Tungsten ring refers to the decorative product that makes with the tungsten steel raw material and will be finished with the cutting, grinding, polishing, etc. up to 30 procedures by using the diamond cutting tools. Because the tungsten steel has white, simple and clear color, and it’s characteristics of uneasy rust, discoloration and no sensitization makes it can also have the excellent performance after being processed of tungsten rings, which have been very popular and been chased by many business people of all ages.
