The lack of grain boundaries in a metallic glass eliminates grain-boundary corrosion—a common problem in high-strength alloys produced by precipitation hardening and sensitized stainless steels. Liquidmetal alloys are therefore generally more corrosion resistant, both due to the mechanical structure as well as the elements used in its alloy.

The best known precious metals are the precious coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art , jewelry , and coinage. Other precious metals include the platinum group metals: ruthenium , rhodium , palladium , osmium , iridium , and platinum , of which platinum is the ...
Silver is known in the chemistry world as a noble metal, which means it is resistant to corrosion, but not completely immune. Whether silver plating or pure silver, the composite of the metal will tarnish when exposed to air and sulfur. Tarnish is a chemical reaction on the surface of metal (copper, brass, silver, etc.) and causes a layer of ...
In metallurgy, non-ferrous metals are metals or alloys that do not contain iron (allotropes of iron, ferrite, and so on) in appreciable amounts.. Generally more costly than ferrous metals, non-ferrous metals are used because of desirable properties such as low weight (e.g. aluminium), higher conductivity (e.g. copper), [1] non-magnetic properties or resistance to corrosion (e.g. zinc). [2]
Costco is again venturing into the precious metals market, expanding its offerings beyond the gold and silver bars it sold to great success. The retail giant now offers 1-ounce platinum bars for ...
