White Gold Platinum Alloy

However copper and silver form undesirable colored oxides in the air or on the skin so other metals are preferable.

White gold platinum alloy.

Platinum is a naturally occurring white metal white gold is created as an alloy of the naturally occurring gold with white metals like silver and palladium to get a white hue. 14k white gold only consists of 58 pure gold while 18k has 75. The purity of white gold is expressed in karats the same as with yellow gold. White gold was originally developed to imitate platinum a naturally white metal.

The cost of white gold and yellow gold is relatively the same as they re both made of gold and other alloy metals. The rest of the alloy is made up of metals such as silver copper and nickel. Any alloy with less than 80 platinum is not considered platinum and cannot be marked with the platinum stamp. While a nickel alloy is hard and strong and therefore good for rings and pins gold palladium alloys are soft pliable and good for white gold gemstone settings sometimes with other metals like copper silver and platinum added for weight and durability although.

Sometimes copper zinc or silver are added. If stamped 18 karat it would be 75 pure gold. As a result white gold alloys can be used for many different purposes. White gold is usually an alloy containing about 75 gold and about 25 nickel and zinc.

In addition white gold pieces are often covered with a thin plating of rhodium a platinum group metal for strengthening and a whiter appearance platinum and white gold resemble each other aesthetically but differ in. White gold alloys in comparison have a lower percentage of pure gold.
