Brass is a copper and zinc alloy with percentages of the latter between 3% to 45%. Occasionally add small amounts of other elements, such as: aluminum, tin, lead or arsenic to enhance some of the characteristics of the alloy. Brass applications cover the most diverse fields, from armament, through ornamentation, footwear and fashion parts, to condenser tubes and electrical terminals. Zinc metal alloys were used during the centuries? Brass pieces dated 1000-1400 BC were found in Palestine and other objects with up to 87% zinc were found in the former Transylvania region. Zinc is a metal sometimes classified as transition metal, although strictly not, and has similarities with magnesium and beryllium, in addition to the metals of its group. This element is little abundant in the earth's crust, but it can be easily obtained. It is known that the manufacture of Brass was known to the Romans since 30 BC. Pliny and Disorders describe obtaining aurichalcum (lathan) by heating in a crucible of a mixture of cadmy (calamine) with copper. The brass obtained is subsequently cast or forged to manufacture objects. Properties of brass that become advantages when it is compared with other metals and metal alloys:Brick? Brass is a metal alloy that features intense shine, strong golden color; Maleability? Brass is very malleable and this property makes the material suitable for making brass sheets and blades; Ductility? Brass can be reduced to wires; Conductibility? Brass is a great driver of electrical and heat energy. We can add to the positive properties of brass its intense mechanical strength and corrosion. These features make brass a different metal alloy from the others, more functional and with ideal properties for vast application. Because of its good characteristics, brass becomes a perfect material for a number of jobs. There are many products that are currently made of brass or have brass components, precisely because this metal alloy has many advantages that show excellent value-benefit ratio: musical instruments, weapons, coins, tacchos and pots, wheels for car, valves, vehicle radiator cores, faucets, decoration objects, jewelry and jewelry, medical and dental instruments, screws, wires and many others.
