Description

Brass L63 is used: for the manufacture of semi-finished products (foil, tapes, sheets, strips, pipes, bars, rods, profiles); the various parts by means of deformation in cold deep drawing, drawing, rolling, stamping, bending; products cryogenic equipment; as the active layer of the thermostatic bimetallic, is used for making sensitive to the temperature change of the elements of control and measuring instruments and apparatus; round drawn thin-walled tubes; drawn rectangular tubes, intended for the manufacture of waveguides; oval, round and flat-oval drawn tubes for the manufacture of the pressure springs; wire for products manufactured by cold heading (bolts, screws, nuts, rivets, studs, screws); radiator tape, is intended for manufacturing cooling tubes and radiator fins; tapes for the manufacture of parts of filtration screens; screw and wire nails used in Shoe industry; hardware products manufactured by cold heading; round welding wire and welding rods round drawn and extruded with a diameter of from 1.2 to 8.0 mm, designed for gas welding brass welding on carbon steel.

Note

Simple (double) brass.
Brass brands L63 suitable for soldering and welding, well polished.

Chemical composition

Standard P Fe Cu Zn Sb Pb Bi
GOST 2060-2006 ≤0.01 ≤0.2 62-65 Rest ≤0.005 ≤0.07 ≤0.002
Cu is the basis.
According to GOST 15527-2004, GOST 2060-2006, GOST 2208-2007, the sum of other elements should be ≤ 0.50%. In brass, the mass fraction of nickel is allowed up to 0.30% due to the mass fraction of copper, which is not taken into account in the sum of other impurities. For antimagnetic brass, the mass fraction of iron should not exceed 0.030%. In brass, used in the food industry, the mass fraction of lead should not be more than 0.050%.
