Wire, round, rod duralumin D1 - 2017

Wire, round, rod duralumin D1 - 2017

Supplier — AvekGlob company — offers wire, round bar, rod, which are made of durability grade D1 (AA2017) 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 D1 brand (the closest foreign analogues produced according to US standards are the alloys AA2017 and A92017) is an aluminum-copper alloy, additionally alloyed with iron, zinc and titanium. The alloy is characterized by low cost, low density, well suited to plastic deformation operations. Dural D1 (AA2017, A92017) is non-magnetic, does not spark during use, has good electrical and thermal conductivity, and chemical / corrosion resistance in the air atmosphere, which can be further increased by anodizing. Anodizing also produces additional decorative finishing of products from this alloy, as a result of which it is poured into the light in various color shades.

Urgency of application

Duralumin deformable alloy D1 (AA2017 and A92017) is used in construction, marine and aircraft industries because of its ease of manufacture, non-toxicity, mechanical strength and resistance to aggressive media found in industry (including chlorine-containing liquids and salts, for example, seawater).

Rolled products from the duralumin D1 (AA2017 and A92017) are widely used in the automotive and aerospace industries, where it produces specialized fasteners, wheels, valve bodies and other heavy loaded structures of complex shapes and sizes.

Chemical composition

According to the technical requirements of GOST 4784−97, D1 consists of the following elements (numerical data — in percent, aluminum basis):

Fe Si Mn Cr Ti Cu Mg Zn Impurities -
up to 0.7 0.2 — 0.8 0.4 — 1 up to 0.1 up to 0.15 3.5 — 4.5 0.4 — 0.8 up to 0.25 other, each 0.05; only 0.15 Ti + Zr <0.2

  • hardness in Brinell, HB — 45… 95 (respectively, for soft and hard dural);
  • the limit of the temporary resistance, MPa — 195… 375 (respectively, for soft and hard dural);
  • yield strength, MPa — 110… 275 375 (respectively for soft and hard dural);
  • permissible tensile elongation,% — 12… 5 (respectively, for soft and hard dural).

Assortment and application features

A wire, a circle, a rod from a duralumin Д1 (АА2017 and А92017) are made in a wide range of cross-sections and length. The initial duralumin preforms after primary plastic deformation — rolling, stamping, extruding — are advisable to age. Aging can be natural (for several days) or artificial (several hours). This treatment optimizes the mechanical properties of the alloy.

Supplier — AvekGlob Company — offers to purchase wire, circle or rod from durability grade D1 (AA2017 and A92017) in the required assortment of cross sections and length. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
