Overview and characteristics of 6 series aluminum alloy

The 6-series aluminum alloy is the aluminum alloy with magnesium and silicon as the main alloy elements and Mg2Si phase as the strengthening phase, which belongs to the heat treatment can strengthen the aluminum alloy.
The alloy has the advantages of medium strength, high corrosion resistance, stress-free corrosion cracking tendency, good welding performance, unchanged corrosion performance in welding area, good formability and process performance, etc.
When there is copper in the alloy, the strength of the alloy can be close to that of 2-series aluminum alloy, and the process performance is better than that of 2-series aluminum alloy, but the corrosion resistance is poor, and the alloy has good forging performance.
6 series alloys are the most widely used 6061 and 6063 alloys, they have the best comprehensive performance, the main product is the extrusion profile, is the best extrusion alloy, the alloy is widely used for building profiles.

The current production of 6 series of aluminum alloy grades: 6005, 6060, 6061, 6063, 6082, 6201, 6262, 6463, 6A02, the following details for you to introduce their respective uses.

Main uses of 6 series aluminum alloy
6005: Extruded profiles and pipes are used for structural parts with stronger requirements than 6063 alloy, such as ladders, TV antennas, etc
6009: The body of the car
6010: Automotive body
6061: All kinds of industrial structures with certain strength, weldability and high corrosion resistance are required, such as pipes, rods, shapes and plates used in the manufacture of trucks, tower buildings, ships, trams, furniture, mechanical parts and precision machining
6063: Industrial profiles, construction profiles, irrigation pipes and extruded materials for vehicles, benches, furniture, fences, etc
6066: Forgings and welded structural extruded materials
6070: Heavy duty welded structures and extruded materials and pipes for the automotive industry
6101: High - strength bars, electrical conductors and heat dissipation equipment for buses
6151: It is used for die forging crankshaft parts, machine parts and rolling ring production, which not only requires good forgability, high strength, but also good corrosion resistance
6201: High strength conductive rods and wires
6205: Thick plates, pedals and high impact resistant extrusions
6262: High stress threaded parts requiring better corrosion resistance than 2011 and 2017 alloys
6351: Extrusion structures for vehicles, water, oil, etc
6463: Buildings and profiles of various appliances, as well as automotive decorations with bright surfaces after anodized treatment
6A02: Aircraft engine parts, complex shape forgings and die forgings
