Wire, round, rod duralumin 3.1355 - AlCuMg2

Wire, round, rod duralumin 3.1355 - AlCuMg2

Supplier — AvekGlob Company — offers wire, bar and rod, which are manufactured from AlCu4Mg2 durability (3.1355) at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Dural of AlCu4Mg2 (3.1355) is an aluminum alloy, which is additionally doped with magnesium and copper. It belongs to the group of thermally hardened aluminum alloys and, after rolling, is always aged, which increases the strength characteristics of the material. AlCu4Mg2 — designation of the alloy according to the Western European standard DIN EN, in North America, the alloy is produced according to the specification UNS A92024. The plastic characteristics of the material are limited, so that its stamping is performed in a hot state or after annealing (at room temperatures, the alloy is only suitable for performing separation operations). It is well suited for anodizing and other surface coating technologies.

Urgency of application

The AlCu4Mg2 (3.1355) duralumin alloy is used in applications requiring a high strength-to-weight ratio, as well as an increased fatigue strength. Typical details are products of transport engineering, space and aviation equipment, as well as decorative and external building structures operating at temperatures down to −200… −250 0 С.

Chemical composition

According to the technical requirements of DIN EN 573, AlCu4Mg2 (3.1355) contains the following elements (numerical data — in percent, aluminum base):
