Noble metals, from a chemical point of view, refer to metals that are highly resistant to oxidation and generally resistant to corrosion.
All noble metals possess low mass abundance in the earth's crust (on average < 10 ppm).
Silver and gold, which with copper are often called the coinage metals, and platinum, iridium, and palladium comprise the so-called precious metals, which are used in jewelry.
Noble metals uses in electronics, jewelry, dentistry, catalytic converters, fuel cells, aerospace components and investment.
Procurement: We procure nobel metals from Sierra Leone, Tanzania & South Africa in the form of Ore, Powder and ingots.
Nobel Metals
GOLD
Gold is a chemical element with the symbol Au and atomic number 79. It is a highly sought-after precious metal due to its inherent value and unique physical properties, including its lustrous appearance and resistance to corrosion. Gold is used in various industries, including jewelry, electronics, and medicine, and has been used as currency throughout history.
RHODIUM
Rhodium is a rare, silvery-white metal in the platinum group. It has the highest known melting point of all metals and is highly resistant to corrosion and oxidation. Rhodium is primarily used as a catalyst in the automotive industry to reduce harmful emissions. It is also used in jewelry, electronics, and as a coating for mirrors and optical instruments.
PALLADIUM
Palladium is a rare and lustrous silvery-white metal in the platinum group. It has a high melting point and is resistant to corrosion and tarnishing. It is widely used in catalytic converters, electronics, and jewelry, and is considered a precious metal. Its atomic symbol is Pd and its atomic number is 46.
IRIDIUM
Iridium is a rare, silvery-white, hard, and brittle metal in the platinum group. It has a very high melting point and is extremely corrosion-resistant. Iridium is mainly used in high-performance spark plugs, electrical contacts, and as a hardening agent for platinum alloys. It is also used in various scientific applications, including in space exploration. Its atomic symbol is Ir and its atomic number is 77.
PLATINUM
Platinum is a dense, silvery-white, and malleable metal that belongs to the platinum group. It has a high melting point, excellent corrosion resistance, and is a good conductor of electricity. Platinum is widely used in catalytic converters, jewelry, and industrial applications, including in the production of fertilizers and nitric acid. Its atomic symbol is Pt and its atomic number is 78.
SILVER
Silver is a soft, white, and lustrous metal that has been valued for thousands of years for its beauty and versatility. It is a good conductor of electricity and is widely used in jewelry, coins, and industrial applications, including in photography and electronics. Silver's atomic symbol is Ag and its atomic number is 47.
