Difference between 6061 and 6063 Aluminum


6063 aluminum is a widely used alloy in the 6xxx series of aluminum alloys. It is primarily composed of aluminum, with small additions of magnesium and silicon. This alloy is known for its excellent extrudability, which means it can be easily shaped and formed into various profiles and shapes through extrusion processes.

6063 aluminum is commonly used in architectural applications, such as window frames, door frames, and curtain walls. Its combination of good strength, corrosion resistance, and anodizing properties makes it suitable for these applications. The alloy also has good thermal conductivity, making it useful for heat sinks and electrical conductor applications.

The mechanical properties of 6063 aluminum alloy include a moderate tensile strength, good elongation, and high formability. It has a yield strength of around 145 MPa (21,000 psi) and an ultimate tensile strength of about 186 MPa (27,000 psi).

Furthermore, 6063 aluminum can be easily anodized to enhance its corrosion resistance and improve its appearance. Anodizing involves creating a protective oxide layer on the surface of the aluminum, which increases its resistance to wear, weathering, and corrosion.

Overall, 6063 aluminum is a versatile alloy with a wide range of applications in construction, architecture, transportation, and electrical industries, among others.
