What's the difference between alloy and composite?

Alloy


Definition:

  • (v. t.) Any combination or compound of metals fused together; a mixture of metals; for example, brass, which is an alloy of copper and zinc. But when mercury is one of the metals, the compound is called an amalgam.
  • (v. t.) The quality, or comparative purity, of gold or silver; fineness.
  • (v. t.) A baser metal mixed with a finer.
  • (v. t.) Admixture of anything which lessens the value or detracts from; as, no happiness is without alloy.
  • (v. t.) To reduce the purity of by mixing with a less valuable substance; as, to alloy gold with silver or copper, or silver with copper.
  • (v. t.) To mix, as metals, so as to form a compound.
  • (v. t.) To abate, impair, or debase by mixture; to allay; as, to alloy pleasure with misfortunes.
  • (v. t.) To form a metallic compound.

Composite


Definition:

  • (v. t.) Made up of distinct parts or elements; compounded; as, a composite language.
  • (v. t.) Belonging to a certain order which is composed of the Ionic order grafted upon the Corinthian. It is called also the Roman or the Italic order, and is one of the five orders recognized by the Italian writers of the sixteenth century. See Capital.
