6063 aluminum bars belong to low-alloy Al-Mg-Si series high plasticity alloys, known for their excellent surface finish, with excellent extrusion performance, good corrosion resistance and comprehensive mechanical properties, and are susceptible to oxidization discoloration.
The alloy is used for standard architectural shapes, custom solids and heat sinks. Due to its conductivity, it can also be used for electrical applications of T5, T52 and T6 tempers.

6063 aluminum bar application selection
Doors and windows profiles
Due to the excellent surface finish of 6063 aluminum round bars, they are widely used in building doors, windows and curtain wall profiles. They are typically extruded from F-temper aluminum die cast bars into T5, T6 and T66 tempers.
For general door and window applications, 6063-T5 aluminum alloy is usually sufficient. 6063-T6 or T66 aluminum alloys can be used if higher hardness is required, though they have higher cost.
6063 has a standard electrical conductivity of 55-63% IACS and can be used for electrical applications in two forms. Aluminum busbar tubes can be extruded from aluminum round bars. Small diameter aluminum rods can also be used for conductive applications. Common tempers are T5, T6 and T52.
Electronics devices and heat sinks
Due to 6063 aluminum bars' good thermal conductivity and electrical conductivity, 6063 aluminum bars are often used to manufacture heat sinks, heat dissipation fins, electronic packaging and other products. Its corrosion resistance also makes 6063 aluminum bars an ideal material for marine electronic equipment.

Characteristics of 6063 aluminum rod
- Strengthened through heat treatment with high impact toughness and insensitive to notches.
- Excellent thermoplasticity, can be extruded at high speeds into complex structural shapes, thin-walled and hollow sections, or forged into complex structural forgings.
- Excellent weldability and corrosion resistance with no tendency to stress corrosion cracking. Among heat-treatable aluminum alloys, Al-Mg-Si alloys are the only alloys where stress corrosion cracking has not been observed.
- Processed surfaces are very smooth and readily anodized and colored.

6063 aluminum rod typical mechanical properties
Typical chemical composition
Effect and influence of Mg
Mg forms strengthening precipitates Mg2Si with Si. The higher the Mg content, the more Mg2Si precipitates form, giving greater strengthening response to heat treatment and higher tensile strength in extruded profiles.
However, resistance to deformation also increases with more Mg, reducing alloy ductility and worsening processability and corrosion resistance.
Effect and influence of Si
Si content should be sufficient for all Mg to be present as Mg2Si precipitates, ensuring the full effect of Mg is realized.
As Si content increases, the grain structure is refined, fluidity improves, castability becomes better, heat treatment response increases, tensile strength increases and ductility decreases in extruded profiles, and corrosion resistance worsens.。
