Brass – Materials and norms
Brass
Brass is an alloy of copper and zinc. For technical applications, grades with at least 58% copper content are significant. Due to the wide range of Cu:Zn ratios and other additives used, the properties of individual brasses vary significantly, leading to their categorization into: alpha brasses, alpha-beta (duplex) brasses, beta brasses, leaded brasses, naval brasses, high-tensile brasses, yellow brasses, white brasses, and silicon brasses. In general, brass has good machinability, corrosion resistance, good electrical and thermal conductivity and a low melting point.
Brass is s commonly used in cases where endurance (corrosion and wear resistance) and/or low friction of components is required, for example in locks, hinges, gears, bearings, firearm cartridges, zippers, water pipes, hose couplings, valves, electrical plugs, brackets, switches, screw down nuts, bridge pins, cams, bushings, pump moldings dies, frames, gears, hooks, hydraulic cylinder parts, large valve stems, propellers, struts, wear rings, boat parts, clamps, marine hardware covers, rudders, gun mounts… For safety reasons (to avoid sparks), brass is applied in fittings or tools used near flammable or explosive substances. Brass is also used in production of musical instruments, dishes, and jewelry.
We supply brass in the form of bars (round, flat, square, hexagonal, hollow), tubes or sheets (plates). We cut semi-finished products into precise pre-final dimensions using band saws.
Below you will find a selection of the most common material grades we work with. Note for European standards (EN): the prefix CC (e.g. CC492K) indicates castings, CB (e.g. CB492K) indicates ingots, and CW (e.g. CW492K) indicates alloys intended for forming. Note for mechanical properties tables: values may vary depending on the manufacturing process and profile – more precise information for a specific semi-finished product is available on request.
