CuZn39Pb3 is alloy of copper and zinc with lead additives . This alloy has similar properties to leaded bronzes . An important advantage of brass alloy is good workability.There can be manufactured a lot of things out of CuZn39Pb3 : complex-shaped devices , watch gears , bearings , branch conduits , pipes for chemical or plumbingequipment Alloy possesses good corrosive resistance. Due to this , it is much-requested in manufacture of cocks , stop valves Due lead additives , there can be easilyobtained different types of mill-products : sheet , bar , wire Plates , strips , sheets , various sections are widely used in mechanical engineering.
