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.

According to GOST 1020-97, nickel can be included in the mass fraction of copper, in this case nickel in the sum of impurities is not taken into account. Total total content of impurities is ≤ 1.80%.
According to OST 24.916.01-71 the total content of impurities is ≤2.10%. The content of nickel is allowed due to the copper content.
