One cannot but agree with the philosophers that form is the highest content. This idea is vividly illustrated by aluminum wire, without which today it is impossible to imagine modern electrical engineering.

Advantages of

Aluminum is very technologically advanced, it melts easily at 600 °C — on the fire of a gas stove. It is cheap, corrosion-resistant, has high electrical and thermal conductivity and weak magnetic properties. The main advantage is high strength at minimum weight. Aluminum wire is resistant to destruction by soil and atmospheric moisture, biologically inert, meets the hygienic requirements of SNIP in the food industry. Welding with aluminum fusion electrode produces a high-strength corrosion-resistant plastic joint.

Production

Production of aluminum welding wire is regulated by GOST 7871−75, using alloys of АМц, АМг5, АМг3, AK5 and АМг6 grades (chemical composition GOST 4784−97). Cold heading wire is produced according to GOST 14 838−78 from alloy B65 and from technical aluminum AD1 (chemical composition is normalized in GOST 4784−97). Preparation and sampling for chemical composition control is carried out according to GOST 24 231−80. Wrought alloys АМц АМГ5, АМГ3 and АМГ6 are easy to work, weld and are resistant to different types of corrosion. AD1 wire has high ductility, electrical conductivity and corrosion resistance. AK5 aluminum wire is produced of minimum diameter from cast aluminum alloys. Due to the enrichment with copper and silicon such wire demonstrates increased hardness. Alloy grade B65 refers to high-strength dural. Cladding or anodic oxidation is used to protect it from corrosion.

— TU 16−705.472−87 — round wire for overhead transmission lines wires.

Accuracy of manufacture:

— usual accuracy;

— P — precision.

Processing of materials:

— aluminum wire without heat treatment;

— M — wire annealed

— N — case hardened

— PT — semi-hardened,

— T — hardened and naturally aged;

— T1 — hardened and artificially aged.

By means of annealing, machinability and plasticity of material by cutting significantly improves, and cold deformation contributes to hardening of the alloy.

— in bundles.

Usage

Aluminium wire is used in mechanical engineering, the food industry, construction and energy. It is used to produce cables, wires, furniture accessories and decorative elements. It is relevant in transport engineering, beer and sausage industry. It is used as strapping and welding electrodes in welding non-ferrous alloys, especially often in welding structures that are in contact with atmospheric or soil moisture. Welding with aluminum wire guarantees:

— high-strength weld,

— prevention of thermal cracks,

— ductility,

— resistance to corrosion.

When welding with aluminum wire, the composition of the weld changes. The alloying elements introduced by welding increase the strength of the weld, but reduce ductility and corrosion resistance. To obtain a ductile corrosion-resistant weld, aluminum structures are welded with an electrode with a minimum of alloying elements. For welding aluminum alloys, as a rule, a wire with a composition close to the chemical composition of the component is used. An exception is the Ai+Mg alloy. Since. magnesium in welding easily evaporates, take a welding wire with a higher percentage of magnesium. than contained in the workpiece.
