What is the difference between 6061 aluminum alloy sheet and 6063 aluminum alloy sheet in terms of material and price

Many customers will be confused about the difference between 6061 aluminum alloy sheet and 6063 aluminum alloy sheet for sale from Haomei in terms of material and price. Indeed, these two materials are very similar, and the market for 6061 aluminum alloy sheets and 6063 aluminum alloy sheets is under-introduced. So today we will introduce the difference between them.

First, let's compare the differences in their materials and characteristics. The main alloying elements of the 6061 aluminum alloy sheet are magnesium and silicon, and form the Mg2Si phase. In Mg2Si, the ratio of Mg/Si is 1.73. In the heat treatment state, Mg2Si is solidified in aluminum, which makes the alloy have artificial aging hardening function. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes there is a small amount of copper or zinc in the 6061 aluminum alloy sheets to improve the strength of the alloy without significantly reducing its corrosion resistance; electrical conductivity There is also a small amount of copper in the material to offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization; in order to improve machinability, lead and bismuth can be added.

Compared with 6061 aluminum alloy sheets, the main alloy elements of 6063 aluminum alloy are magnesium and silicon, which has excellent processing performance, excellent weldability, extrudability and electroplating, good corrosion resistance, toughness, easy to polish, and Coated, excellent anodizing effect, is a typical extrusion alloy, widely used in building profiles, irrigation pipes, pipes, rods, profiles for vehicles, benches, furniture, elevators, fences, etc.

6061 aluminum alloy sheet is best used in various industrial structural parts that require certain strength, high weldability and corrosion resistance. For example, we can use 6061 aluminum alloy to make pipes, rods, shapes, plates for trucks, tower construction, ships, trams, furniture, machine parts, precision machining, etc.

And generally speaking, the hardness of 6061 aluminum alloy sheets is higher. This is because it has more alloying elements than the 6063 aluminum alloy plate, so its material strength is higher.

As for the price of the two, the production cost of 6063 aluminum plate and 6061 aluminum plate is similar, but 6061 is more widely used and the production process is more mature. Therefore, the price of 6061 aluminum alloy sheets is about 0.1-0.2$/kg lower than that of 6063 aluminum plate of the same specification.
