    Description

    Brass lazhmc used: for the manufacture of structural components for critical applications operating at high specific and alternating loads; casting parts, metallurgical machinery (nuts of the adjusting screws; hollow shafts Stripping mechanisms of cranes; and massive crowns worm wheels, heavy duty).

    Note

    Corrosion resistant to action of air and water brass. Brass stamps Lazhmc is a charging material for the melting of brass stamps Lc23a6zh3mc2.
    The maximum permissible speed of rotation 1.0 m/sec. Maximum load capacity: static — 50 kgf/cm2, dynamic — 50 kgf/cm2 sec.
