Technical characteristics

Cast brass (Leaded Brasses) are used with high machinability and resistance to atmospheric corrosion. Processing of these alloys for machine tools is improved due to the increased percentage of lead because it acts as a chip breaker and a well-lubricates the tool. In the compounds of the alloy of brass used in a pair with copper or its alloys. Cast brass is characterized by good strength and corrosion resistance. The lead content distinguish low-, medium -, and vysokovitaminnye brass alloys containing up to 3.5% Pb.

Application

Construction and architecture, manufacturing of parts, working in conditions of high sliding friction. Manufacturer of screws, valves, fittings, bearings and special fasteners.

Types of brass

Standards UNS wrought lead brass marked C31200 — C38500, cast alloys from C83600 C97300 to. Their microstructure contains discrete particles of lead, mainly in the grain boundaries or between dendrite areas. Lead is practically insoluble in solid copper and is present in cast and wrought materials, in the form of discrete particles. Microstructure of low alloy brass consists of twinned grains of alpha with lead particles throughout the matrix. Alloys with higher zinc content contain a mix of alpha and beta phases and lead particles.
