General Characteristics

Double plain brass L63 contains: copper and zinc in an approximate ratio of 63% to 37%. The percentage of copper is reflected in the marking. Brass L63 possesses high technical characteristics: strength, ductility, corrosion resistance.

Production

Chemical composition of L63 grade is regulated by GOST 15 527-2004. The alloy consists of the following components: main part is copper - 62 - 65%, the zinc content is 34,22 - 37,5%. The alloying additives are listed in descending order. Iron - 0.2%, lead - up to 0.07%, antimony - 0.005%, bismuth to 0.002%, phosphorus - ≤0.01, impurities - no more than 0.5%. The alloy is melted at t ° 960 ° C, processed at t ° 750 - 880 ° C, annealing temperature is 550 - 650 ° C. Brass L63A according to the requirements of GOST 15 527 made with antimagnetic properties

Advantages

Brass rolling has a number of advantages over the more expensive copper. In particular, brass 63 has increased strength, easily deforms in cold state, is not prone to corrosion cracking. Increased plasticity allows using it for the production of semi-finished products obtained by deep-drawing of strips, bands, foil.

The mechanical strength at t° 20°C: soft sheet (GOST 2208 - 2007) has _ѕv 270 - 360MPa, _d5 40%; hard sheet (GOST 2208 - 2007) _ѕv = 430MPa, _d5 10%; and semi-solid pipes (GOST 21 646 - 2003) _ѕv = 340MPa, _d5 35%.

Application

Brass L 63 is well deformed in cold state, easily bent, rolled, embossed, polished, available for drawing by deep drawing. It is widely used for the production of tubes, sections and sheets, heat engineering equipment, parts of cryogenic equipment. Manufactured wire for brazing, gas welding copper alloys and cladding on carbon steel.
