Technical characteristics

The duralumin is called a large group of aluminium alloys, which, apart from aluminium, be sure to include copper (of at least 5%) and manganese. In some brands of rare metals (in the designation of these alloys is always present letter D), there are also iron and magnesium. Duralumin rods resistant to external loads at temperatures up to 600⁰ C. They do not differ in corrosion resistance, therefore, operated only in conditions of normal humidity external air.

Application

Duralumin bars used in aircraft manufacturing (the composition of these rare metals is also Nickel), the automobile industry, in construction and architecture as decorative elements. In the latter case, duralumin rods subjected to protective coating.

Treatment

Machinability duralumin rods — satisfactory welding is possible only by means of spot or roller welding.

Aging

The characteristic ability of all duralumin alloys — the ability to aging is to strengthen its positions spontaneously over time. Aging can occur in natural conditions, at temperatures of at least 200 °C, and artificial when duralumin is heated to a temperature of 480…530°C, With exposure for 3…3.5 hours later and a short sharp cooling in water solutions of salts of nitric acid.
