  • The Chemical Composition of White Gold

    Sometimes copper, zinc or silver are added. However, copper and silver form undesirable colored oxides in the air or on the skin, so other metals are preferable. The purity of white gold is expressed in karats, the same as with yellow gold. The gold content is

  • Gold Purity Guide: Difference between 24k, 22k

    18K gold is 75 per cent gold mixed with 25 per cent of other metals like copper or silver etc. Usually studded jewellery and other diamond jewellery is made in 18K gold. This kind of gold is less expensive compared to 24K and 22K. This one has a slightly dull gold colour.

  • Composition of Gold Alloys in Colored Gold Jewelry

    Gold will form alloys with most metals, but for jewelry, the most common alloying metals are silver, copper, and zinc. However, other metals may be added, especially to make colored gold. Here's a table of the compositions of some common gold alloys:

    18K gold is more expensive than 14K gold and the color is a brighter, richer yellow color than 14K gold. The other 25% is made up of other metals such as silver, copper, and zinc. Since 18K gold has a higher gold content than 14K gold (75% vs. 58.3%), it is a softer metal and is not as durable as a 14K gold

    Immersion gold layer features thickness in the range from 0.03μm to 0.1μm. Copper only plays a role in protecting nickel layer from oxidation and dialysis. However, thickness of copper can't be too high, since otherwise, breakdown will take place in terms of brittleness and insecurity. ENIG is simple to operate without need of technical leads.

  • Copper, Silver and Gold University of Denver

    Copper and silver, and perhaps even gold, harden when they have been worked, and it becomes impossible to work them further, even with great effort, without danger of cracking and crumbling. This work hardening is seen even when you bend the lid of a tin can back and forth to break it off.
