    Description

    Brass LA77−2 is used: for the manufacture of tube sheets for condensers and heat exchangers; drawn and cold-rolled pipes used in heat exchangers; seawater-resistant machinery parts; high load fittings; products of medium strength and good corrosion resistance.

    Note

    Complex alloyed brass.

    Cu is the basis.
    According to GOST 15527-2004 the sum of other elements should be ≤ 0.30%. In brass, the mass fraction of nickel is allowed up to 0.50% due to the mass fraction of copper, which is not taken into account in the sum of other impurities.
