Alloys mix metals with other elements to help harden and otherwise make them more useful. For example, gold is too soft to make good jewelry on its own, but it can be mixed with other elements, including harder metals like zinc and nickel, to help make it strong enough ...


Brass, bronze, pewter, and the various types of steel are all common alloys. Alloys differ from pure metals, such as gold, silver and aluminum, because they are mixtures of two or more metals.


Alloys are important because they have properties that differ from those of pure metals. Because of these properties, they can be adapted to specific uses where a pure metal would be either unsuitable or cost-prohibitive.


Steel is an alloy made up of carbon and steel. The combination may vary, but steel is renowned for tensile strength. The carbon and iron form a crystal lattice reinforcing the sturdy metal.


Alloys are made because they contain properties that the pure metal doesn't have, which makes them more useful in practical applications. Alloys can have special properties and can be harder than the original metal, more conductive to heat or electricity, or less prone ...


Examples of alloys are brass, bronze, pewter and steel. Precious metals such as gold and silver are also alloyed with other metals to make durable jewelry.


Copper is a highly conductive, ductile metal. The metal is soft and malleable, although it does possess a great deal of tensile strength. This means that copper is easily formed by hand, but it is not suitable for building structures.
