Pure white gold is very stable, and platinum is the metal with the strongest acid resistance, alkali resistance and high temperature resistance, and will not fade or change color. Platinum rings generally do not deform.

Pure white gold is also very hard. Platinum has a high density and almost twice the strength of gold, making it the best choice for inlaying all kinds of precision. Due to the good properties of platinum, one gram of platinum can pull out 2 km long filaments. The hardness of platinum makes it hard to wear, and platinum lasts as long as new.

Extended data

Pure white gold has many uses. Besides strength and density, platinum has another excellent quality: flexibility. Platinum is very flexible. It only needs 65,438+0 grams of platinum, and it can be drawn into filaments more than 65,438+0 miles (nearly 2 kilometers) long.

This quality combined with the strength of platinum enables jewelers to create extremely flexible mesh platinum jewelry, which other precious metals can never do. Platinum is also essential in other fields: it can be used in industrial fields, especially in catalytic reactors.

Platinum also plays an important role in the medical field. It is not affected by blood oxidation, has excellent conductivity and is compatible with living tissues. Because of these characteristics, platinum is used in pacemakers. More than 50,000 people live a healthy life with pacemakers. Platinum is a life-saving metal.
