Technical specifications
Brass mark LMts58−2 (the nearest foreign analogues — alloys 2.0572, CuZn40Mn2) refers to deformable copper-zinc alloys of medium strength, in which there is no aluminum. The material has medium anticorrosive properties, mainly in the air atmosphere of normal humidity. In view of its good soldering and surfacing properties, it is often used as a surfacing material for ordinary carbon steels.
Urgency of application
Alloy LMC58−2 (2.0572, CuZn40Mn2) is manufactured in accordance with the technical requirements of the Western European standard DIN EN 17660 and domestic GOST 15527−2004. Used for the manufacture of hardware engineering tools, in construction and architecture (interior decoration of public buildings), as well as forged semi-finished products.
Chemical composition
For brass ЛМц58−2 is given in the table (numerical data — in percentage):
Fe | P | Cu | Pb | Zn | Sb | Bi | Impurities |
up to 0.5 | up to 0.01 | 57 — 60 | up to 0.1 | 35.8−42.0 | up to 0.005 | up to 0.002 | only 1,2 |
In foreign analogues, the percentage of iron can reach 1%.
