Platinum is a metal, among the most precious as it is scarcely to be found.
Although it is already used by the Incas to create jewelry, it was officially discovered in the 17th century by the Spanish, who called him a "sinker" that is, silver less.
The success of the platinum is due to its use in the manufacture of parts of firearms due to its high melting point and resistance on the part of the majority of the chemical agents.
Currently, Platinum is used in these areas:
- medicine-surgery (pace-maker, dental implants, chemotherapy, etc..)
- glass processing
- equipment accuracy
- thermocouples - resistance thermometers
- mufflers car
The main characteristics of platinum are:
- heaviness (it has a high specific weight 21.45 g/cm3)
- high melting point around to 1770 °C (compared to 1060 °C for gold)
- steel is practically impervious to the majority of acids)
- ductility (can be worked into sheets, wires, tubes, etc...)
- non-allergenic, well tolerated by almost all skin types)
- does not lose weight over time
- resistant to wear and corrosion
The use of platinum in jewelry
Generally, it is used practically pure (95%) in the watches and various types of jewelry as it stays polished/stainless for a long, long time and is very resistant to corrosion.
Woodworking tools are required, very resistant and high-performance machinery with a particular adjustment, as well as times and higher costs for the recycling of waste.
Platinum jewelry are very shiny and resistant, virtually eternal. The wedding rings in platinum are now very much in demand precisely for these features as you exchange at the altar, as a sign of eternal love.
