Aluminum alloys, along with preserving the advantages of aluminum, have significantly higher strength and better operational and technological characteristics.
Alloys that are not strengthened by heat treatment are characterized by high plasticity, good weldability and high corrosion resistance. Plastic deformation strengthens alloys almost twice. These include alloys based on “aluminum-manganese”, “aluminum-magnesium”, from which pipelines for oil and gasoline, radiators of tractors and cars, welded gas tanks, as well as rivets of ship hulls, building partitions, elevator cabins and other parts are made.
Alloys that are strengthened by heat treatment, namely age hardening, include:
1. Alloys of the aluminum-copper-magnesium system, called duralumins, and heat-resistant alloys of the aluminum-copper-magnesium-iron-nickel system. Duralumins are used to manufacture propeller blades, aircraft spars, building structures, car bodies, for parts that operate at temperatures up to 200...250 °C.
2. "Aviali" are corrosion-resistant alloys of the aluminum-magnesium-silicon system. These alloys are inferior to duralumins in strength, but have better plasticity in cold and hot states. They are used to make sheets, pipes, helicopter propeller blades, forged engine parts, frames and doors.
3. High-strength alloys of the aluminum-zinc-magnesium-copper system, have a strength in the range of 550...700 MPa, but are not heat-resistant. They are used to manufacture skin parts, aircraft spars, and helicopter propeller blades.
