Aluminium Alloy 6061

Aluminium Alloy 6061 | Applications

Aluminum alloy 6061 is very commonly extruded (first infamous is 6063). It is one of the most common alloys of aluminum for general-purpose use. It mainly used in:

Aluminum for transportation is used for car body structure materials for automobiles, subway vehicles, railway passenger cars, high-speed passenger cars, door windows, shelves, automobile engine parts, air conditioners, radiators, body panels, wheels, and ships.

Aluminium Alloy 6061 | Chemical Component

The main alloying elements of the aluminum alloy 6061 is magnesium and silicon and form the Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the harmful effect of iron. Sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing the corrosion resistance. There is still a tiny amount in the conductive material. Copper can offset the adverse effects of titanium and iron on conductivity. Zirconium or titanium can refine grains and control recrystallized structure. This component improves machinability, lead, and antimony. The Mg2Si is solid-dissolved in aluminum, which gives the alloy an artificial age hardening function.

Aluminium Alloy 6061 | Mechanical Properties

Aluminium alloy 6061 is a heat-treated durable alloy with good formability, weldability, machinability, and strength. 6061 t6 aluminum is the primary alloy of 6061. It is a high-quality aluminum alloy produced by a heat treatment pre-stretching process. Its power cannot be compared with 2XXX series or 7075, but its magnesium and silicon alloy have many characteristics and excellent processing performance. Unique welding characteristics and electroplating properties, excellent corrosion resistance, high toughness, and no deformation after processing, compact and defect-free materials, easy to polish, easy to paint, and unique oxidation effect.
