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. More » Science Chemistry

Alloys are homogeneous mixtures that contain uniformly distributed components. Interstitial alloys form when the main alloying agents mix with much smaller agent atoms. The smaller atoms slip into the gaps, or interstice... More » Science Chemistry Atoms & Molecules

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. More » Science Chemistry

Brass does not rust. Only iron and its alloys, such as steel, rust. Pure brass contains no iron and is resistant to corrosion. Brass can develop a red or green tarnish that may resemble rust. More » Science Chemistry

Bronze is an alloy made of 88 percent copper and 12 percent tin. Other metals, such as aluminum, zinc, lead and silicon, are added to it frequently. It is malleable, ductile, lustrous, hard, golden brown in color, and a ... More » Science Chemistry

Bronze and brass are metal alloys, or a mixture of two different metals. The main difference between bronze and brass, therefore, is found in the mixture of metals used to form them. Brass is formed by combining copper w... More » Science Chemistry
