Duralumin foil

Duralumin foil

Supplier — the company AvecGlob — offers at affordable prices from the manufacturer a foil and a pipe that is made of duralumin. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Dural is a large group of aluminum-based alloys, which are further alloyed with copper, magnesium and manganese. Adding copper increases strength. Dyuras is corrosion-resistant, subject to aging and is characterized by high hardness at low density. At the same time, this alloy is well suited for plastic deformation, riveting, welding and heat treatment. After heat treatment, the corrosion resistance of the duralumin increases, which is realized in widely used cladding technologies.

Urgency of application

Dural is used where good strength and good machinability is required. The alloy, in particular, is used in the manufacture of pistons of aircraft engines, piston rings, extruded fittings of aircraft, launch vehicles and other equipment, the operation of which is associated with high temperatures. In the automotive industry, elements of automatic body panels are produced from the duralumin. In transport, duralumin is used for the production of external sheathing of transport containers.

Chemical composition

The composition of the duralumin usually includes aluminum (about 90%), copper (about 4%), magnesium (about 2%) and from 0.5% to 1% manganese. Traces of titanium and zirconium can be present as impurities.

Physical and mechanical properties

Dural is a very good conductor of heat and electricity. It has no odor, and under normal conditions it reacts quickly with oxygen in the air, forming a strong and solid alumina film.

Assortment and application features

Foil and pipe made of duralumin are produced in a wide range of diameters, thickness and length. Initial duralumin preforms after primary plastic deformation — rolling, stamping, extruding — must be subjected to aging. Aging can be natural (for several days) or artificial (several hours). This treatment optimizes the mechanical properties of the alloy.

Supplier — the company AvekGlob — offers to buy a foil or pipe from duralumin of various brands in the necessary assortment of diameters, thickness 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.
