260 Brass Sheet and Plate

C26000 Brass Sheet and plate, produced as a combination of copper and zinc, has the highest ductility in the yellow brass series. It is an attractive material with a smooth, yellow brass finish. It may be polished to a gold like appearance or given a brushed (satin) finish. 260 Brass can be used in corrosive enviroments. 260 Brass forms a thin protective “patina”, which, unlike steel and iron, will not rust when exposed to the atmosphere.

APPLICATIONS

260 Brass has a wide range of applications, such as appliance parts, highly formable parts, ammunition components, decorative parts of furniture and cabinets, name plates, engraving plates, overlays, legend plates, lamp fixtures, fasteners, locks, hinges, flashlight shells, connectors, fittings, circuit board relays, electronic components, switches, nuts, bolts, valve stems and valve components, radiator cores and tanks, brackets, frames, fixtures, ornamental works, and used extensively in the musical instrument, electrical equipment, plumbing, central heating, seawater lines and desalination fields.

MACHINEABILITY AND WELDABILITY

In its half-hard condition, 260 Brass has a machinability rating of 30 as compared to 360 brass rated at 100. 260 Brass has the highest ductility in the yellow brass series. Welding is not recommended, although 260 Brass has low to fair soldering and brazing capabilities. 260 Brass has poor butt-welding characteristics.
