Precious metal alloys are a mix of rare metals that possess unique characteristics different from those in traditional metal base alloys. Each precious metal in the mix offers valuable properties that give the alloy its superior nature. Keep reading as we tell you more about the common elements found in precious metal alloys and their applications.
Important Components of Precious Metal Alloys
Most precious metal alloys contain rare and valuable metals in different ratios. Gold, silver, palladium, platinum, etc. bring special properties to alloys, which may differ depending on the overall configuration. Each metal used in the blend affects the physical and mechanical properties of the overall product. Shape, strength, malleability, ductility, conductivity, melting point, tensile strength, resistance to corrosion, yield strength, etc. are important properties that define how and where the alloy can be applied.
Gold is a commonly used precious metal in manufacturing alloys. It has high corrosion resistance, with high electrical conductivity. It mixes well with silver, copper, nickel, and other metals to form metal contacts. Alloys featuring gold are widely used for making jewelry, currency, and certain electronics.
Known for its excellent electrical and thermal conductivity, silver is a shiny and lustrous metal that’s soft and is highly resistant to oxidation. This makes it a useful material for manufacturing contact materials. Pure silver is too soft to be used for commercial applications, so producers blend it with nickel to form sturdy alloys. Silver-based alloys are widely used in electronics and power industries that look to leverage the outstanding capability of this metal to transfer electricity.
Platinum is a silvery-white metal with good anti-corrosive properties and when combined with Iridium offers excellent elasticity. Alloys made with platinum are useful in catalytic converters, laboratory equipment, electrodes, and jewelry.
Palladium is a soft and ductile material with good corrosion resistance and can absorb large amounts of hydrogen at room temperature. It’s used primarily in catalytic converters, electronics, and jewelry.
Iridium has a high melting point and is a brittle metal, which is also corrosion-resistant, even at very high temperatures. It’s a very expensive material that finds applications in very specialized applications.
Precious metal alloys are used in several industries, including electronics, chemicals, aerospace, medical, and more. High conductivity metals such as silver and copper are used in the manufacture of powder metal contacts.
