White gold
White gold has been known since antiquity as (platinum), and it is one of the chemical elements in the periodic table, which is symbolized by the symbol (Pt), and this element has many features that give it its qualities, as it is a transition metal with a gray-white color
It is characterized by the magnetic properties of parallel and hardness, and its tensile strength is high up to 125-245 gigapascals, its boiling point is 3825c, its melting point is 17680c, its volume factor is 230 gigapascals, and the platinum element has a strength greater than that of iron.
Its flexibility is similar to that of ordinary gold, and the reason for calling platinum by this name is due to the Spanish word (plata) meaning (little silver), and platinum is one of the precious metals and has a special place, which made it expensive in different markets.

The history of the discovery of white gold dates back to the year 1557 AD, when the Italian scientist (Julius Scaliger) was the first to discover this element for the first time, and then the Spaniards discovered more large quantities of this distinctive metal in the year 1750 AD, when it was initially sold at cheap and cheap prices because Its value was not traded as it is now.
white gold qualities
Big strength, high toughness. Not affected by the surrounding environmental influences, white gold does not rust and does not lose its luster over time. Resistant to high temperatures and corrosion. Good resistance to acidic elements, which have the ability to affect other metals. It has good flexibility, as it can be dissolved by mixing it with nitric and hydrochloric acid.
How to distinguish white gold
White gold can be distinguished in many ways, the most important of which is: Scratching a piece of gold, and if it is scratched, it is white gold. Heating a piece of gold a lot until it turns into a flame, and if its color after cooling turns to a dark color, it is white gold. Exposing it to some alkaline acids, and if it melts, it is white gold.

It is used in the manufacture of jewelry and ornaments; Because of its hardness and unaffected by climatic factors such as air and rust, and its luster lasts for long periods. Contributes to the removal of toxic gases found in nature
When combined with it, it turns into nitrogen gas, water vapor, or carbon dioxide. It is included in the field of chemical analysis laboratories in which samples are dissolved when mixed with various acids. It is used in the manufacture of panels and thin wires, which are used in many electrical purposes and equipment.
It helps to analyze and dismantle the components of oil separately. It is used in the manufacture of medical teeth, surgical and laboratory tools, and is used in the manufacture of chemical compounds that have an effect in the treatment of cancers of all kinds. It is used in the auto parts industry, as it is used in the installation of the catalytic converter in automobile exhaust.
