D16T - dural sheet, strip, pipe
Supplier — AvekGlob company — offers at reasonable prices from the manufacturer a sheet, tape, pipe, which are made of duralumin brand D16T. The supplier guarantees the timely delivery of products to any address specified by the consumer /
Durale brand D16T (the nearest foreign analogues — the alloys 3.1355 and AlCu4Mg2) is an aluminum alloy, which is additionally alloyed with magnesium and copper. In contrast to alloy D16, after rolling, it always undergoes aging, 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, and therefore its stamping is performed in the hot state or after annealing (at room temperatures, the D16T alloy is only suitable for performing separation operations). It is well suited for anodizing and other surface coating technologies.
Urgency of application
Durant brand D16T is used in applications requiring a high strength-to-weight ratio, as well as 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.
According to the technical requirements of GOST 4784−97, the structure of the D16T duralumin includes the following elements (numeric data — in percent, aluminum base):
|up to 0.5||up to 0.5||0.3−0.9||up to 0,15||3.8−4.9||up to 0,1||1,2 — 1.8||up to 0.25||other, each 0.05; only 0.15|
