Manufacturing

Production includes horizontal casting, broaching with subsequent calibration to improve accuracy of parameters and optimization of automatic metal processing lines. The chemical composition of LC40-S and LC40-SD grades is normalized by GOST 17 711-93. As follows from the abbreviation composition of this brass includes about 40% of zinc, more precisely 35 - 42,2% Zn. Copper constitutes the main part: 57 - 61% Cu. Then in descending order: 0.8 to 2% of lead, up to 1% of nickel, up to 0.8% of iron, 0.5% each of manganese, tin and aluminum, 0.3% of silicon, 0.05% of antimony. Permissible proportion of extraneous impurities - less than 2%.

Advantages

Brass rolling has a number of advantageous qualities compared to more expensive copper. In particular, brass ЛЦ40-С and brass ЛЦ40-СД has pronounced antifriction qualities. Due to excellent manufacturability the products of any profile and complexity can be produced. Brass LC40-S is characterized by minimal shrinkage during casting, which in turn provides the highest quality product. The negligible propensity to the process of liquation, which has brass LC40-SD allows it to be used for the production of a wide range of metal products. At t° 20 °C the index _d in - for casting into the sand mold, casting into the or centrifugal mold is 215 MPa, index _d5 (in %) for casting into the or centrifugal mold = 20%, for casting into the sand mold = 12%.

Application

Production of shut-off sanitary parts, casting of sleeves and cages for roller and ball bearings. Production of manometric and condenser tubes, sleeves of chemical equipment. For mechanical engineering manufacture of engine cooling systems.
