BRASS

Brass is a metallic alloy that is made of copper and zinc. The proportions of zinc and copper can vary to create different types of brass alloys with varying mechanical and electrical properties. Brass has a bright, gold-like appearance. Applications include locks, gears, bearings, doorknobs, ammunition casings and valves. Also plumbing parts, electrical parts and musical instruments such as horns, bells and zippers. Since brass does not spark it can be safely used near flammable or explosive materials.
