Gilding, a decorative process, is one of the commonly used vocabulary. It originally referred to a thin coating of gold on the surface of an object.

Gilding is divided into two types, one is made of homogeneous material and the other is made of different materials. The gilding of homogeneous materials refers to gilding the surface of gold jewelry. Its significance is to improve the brightness and color of jewelry. The gilding of heterogeneous material, here introduces the gold-plated tungsten alloy, which is plated with gold to make it has golden appearance. Its purpose is to replace the color of the plated material with the gold luster, so as to improve the ornamental effect of the jewelry. But what is the difference between gold-plated tungsten alloy and gilding? And how to identify its pros and cons?

In general, homogeneous gilding doesn’t need to be plated too thick, 2 microns is all right. Heterogeneous gilding should be thicker. Some countries stipulated that such products should be plated more than 10 microns. Usually, tungsten alloy plated gold is not pure gold, but K gold, while gilding basically plated with pure gold.

 

 

The quality of gold plating depends on the thickness, brightness of the gold coating. Take the case of gold-plated jewelry, the current international standard of gold-plated jewelry is: good gold-plated jewelry thickness is10-25 microns; the average gold-plated jewelry coating thickness is 2-3 microns; if below 0. 18 microns, it cannot be called "gold-plated", it belongs to cheap jewelry craft.

 

Whether it’s homogeneous materials gilding or heterogeneous materials gilding, gold-plated jewelry quality depends on the gold plating process, which has a very high demand. As tungsten alloy contains tungsten, it has high density, corrosion resistance, abrasion resistance, easy processing, and not easy deformation, which make gold-plated tungsten alloy products has a high degree of wear. We can see some gold-plated tungsten alloy jewelry can be used for decades with the unchanged appearance, and it does not reveal inner core, Gold-plated tungsten alloy jewelry. Gold-plated tungsten alloy products are very popular among business people.
