The biggest difference between tungsten gold-plated and gold is their different substrate materials, tungsten gold-plated products is to plate the gold in the tungsten products surface, but its essence is still a tungsten material. While the substrate material of gold is still gold. Of course, the gold surface also can be gold-plated, as for its purpose to do so is just in order to increase the surface color of the original gold so as to achieve the purpose of pleasing. Since tungsten and gold have more similar densities, the density of gold is 19.3g / cm3, and the density of tungsten is 19.35 / cm3, so both have relatively similar touch feelings.

 

However, gold has a strong chemical affinity, so it would be easy to have a reaction with acid gases of hydrogen sulfide in the air, which will make its surface color turn to dim. The hardness of gold is inferior to tungsten gold-plated, therefore gold jewelry can be easily abraded if wearing in daily life. But for the tungsten gold-plated, its high hardness characteristic make it able to overcome the abrasion problem. In addition, tungsten has the properties of non-toxic, environmental protection, good corrosion resistance, so no matter what aspect the tungsten gold plated products apply in, they can be well maintained without changing original states, and cause no pollution to the environment. In short, from a price point of view, it’s too clearly that the tungsten gold-plated can’t compared with gold, but from the ornamental and practical point of view, tungsten gold-plated products have ability to replace the expensive gold products.
