Extruded 6063 6082 7050 7075 Standard Size Solid Aluminum Round Bar
6063 Aluminum Bar Characteristics:
6063 aluminum bar is one of the most popular extruded aluminum product grades. While high wear applications and critical support applications are not recommended for this grade, it is easily anodized which gives it excellent corrosion resistance.
6063 aluminum bar has a number of advantages, namely good electrical conductivity, good candidate for extrusions, and a high-quality surface finish. When heat-treated, it offers good corrosion resistance. It can also be anodized in the T5, T52, T32, T54, and T6 tempers. Its main disadvantage is that it has a poor strength-to-weight ratio.
6063 aluminum bar is seen across a wide range of industries, including the construction, architectural, building products, home goods, irrigation, appliance, marine, aerospace, and automotive industries.

6063 Aluminum Bar Surface Corrosion:
The behavior of 6063 aluminum alloy profile corrosion caused by silicon can be completely prevented and controlled, as long as the raw material purchase and alloy composition are effectively controlled to ensure that the ratio of magnesium to silicon is within the range of 1.3 to 1.7, and the parameters of each process are strictly controlled To avoid segregation and free of silicon, try to make silicon and magnesium form a beneficial Mg2Si strengthening phase.
If this kind of silicon corrosion point phenomenon is found, special attention should be paid to the surface treatment. In the process of degreasing and degreasing, use a weak alkaline bath as much as possible. If the conditions do not allow it, it should also be soaked in acid degreasing liquid for a period of time.
As short as possible (qualified aluminum alloy profiles are placed in acidic degreasing liquid for 20-30 minutes without problems, and problematic profiles can only be placed for 1 to 3 minutes), and the pH of the washing water should be higher (pH>4, control Cl-content), as long as possible during the alkali corrosion process, the nitric acid light solution should be used when neutralizing the light, and the oxidation treatment should be energized as soon as possible during the anodization of sulfuric acid, so that the dark gray corrosion points caused by silicon are not obvious, To meet the requirements of use.
How does 6063 aluminum compare to 6061 aluminum?
When it comes to aluminum bar, 6061 has excellent corrosion resistance, good workability, and good machinability. It is used for all types of fabrication projects including aerospace, medical assemblies, transportation, and structural components.
In comparison, 6063 has superior corrosion resistance and a fine appearance and finish. Beyond their mechanical properties, 6063 is an attractive alternative to 6061. For that reason, you’ll find it in lightweight applications that require a superior finish in addition to corrosion resistance. It is a favorite for outdoor architectural trims.
