    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.
