Supplier — AvekGlob Company — offers wire, round bar, rod, which are made of duralumin of grade D12 (АА3004, АА3104) at reasonable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Dural brand D12 (the nearest foreign analogues produced by US standards — alloys AA3004 and AA3104) is an aluminum-copper alloy, additionally doped with manganese. These alloys are not subjected to heat treatment. They have an excellent combination of corrosion resistance and formability. An increase in the mechanical characteristics of the alloy can be achieved as a result of its plastic deformation at ordinary temperatures.

Urgency of application

Duralumin deformable alloy grade D12 (AA3004 and AA3104) is used in construction, maritime and aircraft construction due to the ease of manufacturing, non-toxicity, mechanical strength and resistance to aggressive media found in industry (including chlorine-containing liquids and salts, for example, sea water) .

Rolled products from the material in question are widely used for the production of fasteners, valves, wheels, fittings, and forgings intended for subsequent machining.

Chemical composition

According to the technical requirements of GOST 4784−97, D12 consists of the following elements (numerical data — in percent, aluminum basis):

The chemical composition of the alloys AA3004 and AA3104 is regulated by the requirements of the UNS specification A93104.

Assortment and application features

The rod, circle, D12 wire (AA3004 and AA3104) are produced in a wide range of cross-sections and lengths. 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. The alloy is well deformed both at room temperature and at elevated temperatures.

Supplier — AvekGlob company — offers to buy bar, circle, D12 wire (AA3004 and AA3104) 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.
