D16 - 2024 duralumin sheet, strip, pipe
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a sheet, tape, pipe, which are made of durability grade D16 (AA2024, AA2124). The supplier guarantees the timely delivery of products to any address specified by the consumer.
Dural of D16 brand (the nearest foreign analogues, produced according to US standards — AA2124 and AA2024 alloys), is doped with manganese and copper. The alloy is distinguished by its high strength, including fatigue strength, but it is poorly welded and has average machinability indices on metal cutting machines. The indices of plastic deformability are average: in particular, sheet and tube sheets are subject only to separation operations. Corrosive properties are unsatisfactory, as a result of which this alloy is often aluminized or zinced, although this can reduce fatigue strength.
Urgency of application
Dural of D16 brand (AA2024, AA2124) is used in applications requiring a high strength-to-weight ratio, as well as increased fatigue strength. Typical parts — products of transport engineering and aviation, as well as other devices that operate at lowered −200… −250 0 С temperatures.
According to the technical requirements of GOST 4784−97, D16 consists of the following elements (numerical data — in percent, aluminum basis):
|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|
In the composition of the alloy, up to 0.05% of zirconium is allowed.
The chemical composition of alloys AA2124 and AA2024 is regulated by the requirements of the UNS A92024 specification.
