Precious Metal Alloys (PMAs) are the product of a material alloying process. During these processes, heating or treating metals under high temperatures, they undergo changes in physical properties by changing their chemical composition, to produce high-grade alloys that possess qualities that can be used in various applications
In other words, PMAs are the result of alloying metals with precious metals like gold, silver, platinum and palladium. These materials are used for their unique properties such as resistance against corrosion, strength and durability. Moreover, they are also used as catalysts within chemical processes
Precious metal alloys can be produced by combining two or more elements together in different proportions to create new materials with different properties than the original component parts. For example, a mixture of iron and nickel can be combined with another element such as aluminum to form an alloy with improved strength and resistance against corrosion compared to pure iron or pure nickel alone.
forging processes are performed on molten liquid metals
