Free Machining Brass
Brass is essentially copper alloyed with zinc. It is strong but easy to form, stamp or draw which make it a common choice for a broad spectrum of applications. By varying the amount of zinc content it is possible to achieve a variety of characteristics including different levels of corrosion resistance, ductility and suitability for machining.

Forging Brass
Forging Brass is an alloy of copper and Zinc, in properties which can be varied to achieve varying mechanical and electrical properties. It is a substitution alloy: atoms of the two constituents may replace each other within the same crystal structure. Forging brass can be easily shaped. Forging brass has high thermal conductivity and have exelent hot forgeability properties. They are available in the form of rod.

Naval Brass
Naval brass is the classic marine, high-strength and corrosion-resistant alloy containing 60 percent copper, .75 percent tin and 39.2 percent zinc. The addition of Tin also gives Naval Brass a high resistance to dezincification. It is widely used in marine construction where strong, corrosive-resistant and hard material is required and is suitable for both salt and fresh water applications. Naval Brasses have good strength and rigidity. The alloys are noted for their resistance to wear, fatigue and stress corrosion cracking.

Leaded Brass
Lead increases the machinability of brass as well as increasing its strength and resistance to corrosion. The addition of lead also seals shrinkage pores to provide pressure tightness. Brasses can contain up to 3.5 percent in lead contents, and are classified as low, medium, or high-leaded. Leaded brass may be used to make screws, valves, fittings, bearings, specialty fasteners, architectural hardware, and general purpose machine parts.

Lead Free Brass
Lead free brass possess relatively good corrosion resistance, moderately high strength, and in some forms, it has very good ductility. Its hot forms are strong. It also called Muntz metal. It is available mainly in 60/40, 63/37, 65/35 & 70/30 Cu/Zn ratio. A ductile alloy is suitable for blanking, riveting, bending, hot forging & pressing.
