There is no difference between 18k gold and 18k gold. They are subordinate, but strictly speaking, 18k gold is not real gold, which is not substantially different from 18k gold. Perfect 18k gold not only has good ductility of gold, but also has good hardness and plasticity of alloy, which is widely used in jewelry design and industry.

There is no difference between 18k gold and 18k gold. There is no difference between 18k gold and 18k gold, because 18k gold and 18k gold are subordinate, but strictly speaking, the gold content of 65438+ gold is above 95%.

The perfect 18k gold is composed of 75% gold and 25% alloy, with a moderate proportion. With good ductility of gold and good hardness and plasticity of alloy, the whole 18k gold presents different colors due to different compositions, which has been widely used in jewelry design and industrial fields.

With the rapid development of modern industry, 18k gold is widely used. When processing some objects, 18k gold is usually plated to ensure the quality of the objects, and it also has a good heat conduction effect.
