    Description

    Brass L90 is used: for the manufacture of semi-finished products (strips, sheets, strips, rods); the various parts by means of deformation in cold deep drawing, drawing, rolling, stamping, bending; 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; wire for parts for electrical engineering; medals and badges; radiator tape, is intended for manufacturing cooling tubes and radiator fins; tompakova cold-rolled strips and strips used for plating; strip thickness 0,5−1,08 mm, intended for the production of elements of target ammo; extruded bars with a diameter from 60 to 120 mm for the shipbuilding industry.

    Note

    Simple (double) brass.
    Brass brand L90 very well deformed in a cold state, especially by drawing; not prone to stress corrosion cracking; suitable for forging, stamping, and enameling.

    Cu is the basis.
    According to GOST 15527-2004, GOST 2208-2007, TU 48-21-816-86 the sum of other elements should be ≤ 0,20%. 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%.
