What is the difference between 6063 aluminum sheet and 6061 aluminum sheet material?

6063 aluminum sheet 6061 aluminum sheet

6063 is generally used in building profiles.

The main alloying elements of 6063 aluminum alloy are magnesium and silicon, which have excellent processability, excellent weldability, extrusion and plating, good corrosion resistance, toughness, easy polishing, coating, and anodizing effect. It is a typical extruded alloy, widely used in building profiles, irrigation pipes, pipes, rods, profiles for vehicles, benches, furniture, elevators, fences, etc.

6061 Requires a variety of industrial structures with certain strength, weldability and high corrosion resistance, such as the manufacture of tubes, rods, profiles, trucks, towers, ships, trams, furniture, mechanical parts, precision machining, etc. Generally speaking, the plate has more alloy elements than 6063, so the material strength is higher

The main alloying elements of 6061 aluminum alloy are magnesium and silicon, and form a Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to increase the strength of the alloy without significantly reducing its corrosion resistance; there is still a small amount in conductive materials Copper to counteract the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine the grains and control the recrystallization structure; in order to improve machinability, lead and bismuth can be added. In Mg2Si, the Mg / Si ratio is 1.73. In the heat-treated state, Mg2Si is solid-melted in aluminum, so that the alloy has an artificial aging hardening function. 6061 requires industrial structural parts with certain strength, solderability and high corrosion resistance.
