Interesting Facts About Alloys Which Are Blends of Metals
Aug 11 2019 · Although sterling silver is an alloy consisting mainly of silver many alloys with the word "silver" in their names are only silver in color. German silver and Tibetan silver are examples of alloys that have the name but don t contain any elemental silver. Many people believe steel is an alloy of iron and nickel but it consists primarily of iron carbon and any of several other metals.
