Brass is a strong alloy produced by having copper and zinc melted together. It is used for metal decorations, for its shiny gold-like appearance; for mechanisms, for it features low friction which is needed in locks, gears, bearings, doorknobs, ammunitions, and valves; for plumbing and electrical applications, as it is malleable; and for musical instruments, due to its excellent acoustic properties. Brass is one of the major alloys used in many industries. Because it is softer than most other metals used generally, brass is often used in cases where it its utterly important that sparks not to be struck, such as in fittings, tools and devices on inflammable ad explosive gases. In terms of appearance, brass is muted-yellow in color, which associates it with similarity to gold. It is considerably resistant to tarnishing and oxidation, and is often used as metal decorations and for coinage. During the olden times, polished brass was often made into mirrors. Although types of brass have been utilized since prehistoric times, its real nature as an alloy of copper and zinc was not realized until the late medieval period, because the zinc vapor which reacted with copper to make brass was not considered as a metal. The first brasses to come out may have been naturally made out by smelting copper ores rich with zinc. By the Roman era, brass was produced by cementation process of metallic copper and zinc minerals, which persisted until the mid-nineteenth century. It was then replaced by direct alloying of molten copper and zinc metals, or speltering, which was developed by early waves of brass manufacturer and Brass Distributor in the sixteenth-century Europe. To date, a Brass Distributor may provide types of brass for either general or specialty uses. For instance, a company may make produce specialty brass for firefighting equipment, such as fire- and wear-resistant valves, nozzles and emergency equipment. That company may also manufacture brass for plumbing. These include faucets, bath and lavatory supplies and other accessories to serve both residential and commercial uses. Other Brass Distributor outlets supply other industries with brass for musical instruments, brass fittings, lacquers, fasteners, rings, pipes, caps, nozzles, rods, wires, plates, and other intended applications for the brass alloy.
