Diamonds in metal! Bring you the charm of tungsten
Speaking of the jewelry materials that are usually worn, gold, platinum, gold, silver, and new metals such as tungsten gold and titanium are also common. Among the many metals mentioned above, tungsten gold is the least common, many people do not know. What is tungsten gold? Today, Xiaobian will bring you a comprehensive understanding of tungsten gold!
What is tungsten in the end?
Tungsten gold is the full name of tungsten carbide alloy, and the industrial field is also called tungsten steel. Tungsten is a rare metal. The tungsten ore is refined into 60% or 90% tungsten powder by mining, grinding, water re-election, refining, etc., and the finished product produced by high-temperature electric furnace is tungsten strip.
The melting point of the tungsten bar is about 3500 °C. Tungsten mines are mainly distributed in China and Russia. Generally, the purity of the tungsten rod should be above 99.95%, and the inspection and analysis report of the authority must be issued, for example, the analysis report of the National Nonferrous Metals and Electronic Materials Analysis and Testing Center or the universally recognized standard of compliance (SGS).
Tungsten gold jewelry is mainly produced in China. Known as "the diamond in the metal", it has a diamond-like texture and exudes a gem-like luster. Therefore, it is recognized by the fashion industry as a metal material that can be compared with diamonds. Tungsten gold jewelry is made of high-purity tungsten gold (tungsten gold with a tungsten carbide content of 90% or more) and processed by a special process. The surface of the jewelry is excellent in gloss and does not wear out and fades!
White tungsten gold
Tungsten gold jewelry has: high hardness, gloss and texture, but the color is black and bright, can not reach the ideal silver white of some consumers. White tungsten gold is a product of the aesthetics of consumers.
White tungsten gold: also known as tungsten gold plated platinum.
The manufacturing process of white tungsten gold: the formed tungsten gold jewelry and platinum powder are placed together in a 3000 degree high temperature furnace, and the platinum powder is slowly dissolved into the tungsten gold jewelry in a vacuum environment, thereby making the tungsten gold jewelry reach more. White brighter visual effects;
The jewellery made of white tungsten gold also has the hardness, gloss and texture of tungsten gold jewelry, no discoloration and no wear, but the color will be whiter and closer to silver than the jewelry directly made of tungsten gold.
Soft tungsten
Soft tungsten gold refers to a tungsten gold bar with a tungsten content of about 18% and a gold content of 80% or more. Because of its high gold content, its value, or market price, is much larger than tungsten gold plating.
Soft tungsten gold is mainly based on gold and adds a small amount of tungsten so it is actually a gold alloy. The concept of tungsten is relatively confusing, and many people are thus deceived by lawless elements to cause property damage. In general, the appearance of soft tungsten gold is as golden as gold, but we can still judge the difference between gold and soft tungsten gold from the naked eye and the hand.
Although soft tungsten is almost similar to gold, its main purpose is to satisfy the hobbies of many collectors or souvenirs used by friends. The value is not a substitute for gold, and it cannot be used for illegal things.
With the development of technology, soft tungsten is added to tungsten, and its corrosion resistance, wear resistance and conductivity are excellent. The thermal insulation and good ductility of gold also make soft tungsten gold not only used. The production of collectibles and ornamental items such as gold bars, handicrafts, and jewellery can also be applied to industries such as aviation and nuclear research.
