Description

Brass Lmcs is used: for the manufacture of structural parts, equipment and shipbuilding; anti-friction parts with a simple configuration; the reinforcement of railway bearings; casting parts, metallurgical machinery (bearings, bushings and other friction parts, including reinforcement of railway bearings).

Note

Brass stamps Lmcs is a charging material for the melting of brass stamps Lc38mc2s2. The coefficient of friction of brass without lubrication of 0.24, with a lubricant — 0,016. Maximum load: static 100 kg/cm2, the dynamic is 60 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 ≤2,20%.
According to OST 24.916.01-71 the total content of impurities is ≤ 2.50%. The content of nickel is allowed due to the copper content.
