Platinum
Chemical symbol: Pt
Specific gravity: 21.45 g/cm³
Colour: Silver-white
Melting temperature: 1768?C
Platinum, shiny and with high density, i is often combined with gold to create extremely solid alloys. The presence of this metal in fact gives hardness, increases the melting range of the alloy, increases resistance to corrosion and oxidation, lightens the colour of the alloys and contributes to the improvement of mechanical properties. Historically, the high cost of platinum and its limited availability have meant that it is often replaced by palladium even if in recent years (n.d.r. 2020) the price trends have reversed that see palladium with a much higher price than platinum
This metal is used in the manufacture of laboratory equipment, catalysts, in the medical-dental field and for the formation of electrodes and precious objects.
The platinum sold by Banco Villa is guaranteed for the fineness of 999.5&per th. as well as for the part relating to the impurities present in the metal, in addition to meeting the ASTM standards. The platinum sold by Banco Villa can also be requested with a traceable batch number and from sustainable and responsible sources (RJC COC).
