The difference between words is two concepts.
There was no Wujin in ancient times.
Simply put, Wujin is made of platinum after special treatment. Tungsten gold is an alloy material containing tungsten. Ancient bronze mirrors containing tungsten were called tungsten gold bronze mirrors. Because tungsten (W) is a rare metal, the proven reserves in the world are very few, and people habitually call it tungsten gold because of its scarcity. In tungsten gold jewelry, the content of tungsten usually reaches more than 80% before it can be called tungsten gold.
The following are the differences between Wujin and Tungsten Gold:
Wujin: The special treatment of platinum makes it black, but it exudes the light of platinum, so the price of imitation jewelry plated with hardware is more expensive than that plated with pure gold; The logo of 18Krgp is usually found on the regular gold-free jewelry, but some counterfeit products will also be engraved with this logo, but the counterfeit products are generally treated scrap iron. 1-2 months later will rust, while the genuine products will not fade for several years!

Tungsten and gold are rare non-ferrous mineral products in the world, with low annual output and wide applications, which are mainly used as raw materials for casting ingredients. Tungsten and gold come from a Baisha ore body with a very small ore line. After mining, grinding, water-gravity separation, refining and other processes. Tungsten powder with a grade of more than 95% is obtained, and then the finished product produced by refining and molding in a high-temperature electric furnace is tungsten gold. Melting point of tungsten and gold: 3500℃. At present, tungsten ores are mainly distributed in China and Russian, and China is now the largest exporter of tungsten and gold in the world. Usually, the purity of tungsten and gold should be above 99.95%, and the inspection, analysis and test report of authoritative organization, such as the analysis and test report of National Nonferrous Metals and Electronic Materials Analysis and Testing Center, must be issued.
