Native Platinum

Platinum luster is metallic; its hardness is 3.5-4.5. Platinum streak is silver-grey and shiny; and its density is extreme at 21.45, but decreases to less than 20 near its melting point of 1769ºC. Impurities in natural native platinum lower its density to 14-19, and iron impurities may impart a slight level of magnetism.

Platinum-Group Elements—So Many Excellent Properties

The platinum-group elements (PGE) include platinum, palladium, rhodium, ruthenium, iridium, and osmium. These metals have similar physical and chemical properties and occur together in nature. The properties of PGE, such as high melting points, corrosion resistance, and catalytic qualities, make them indispensable to many industrial applications.
