Aluminum alloys with different alloying components, as well as those with the same components but varying contents, exhibit distinct properties. To differentiate aluminum alloys by their components and component contents, the international community has assigned a unique designation to each type of aluminum alloy. These consistent designations facilitate more convenient communication and transactions.
Today, let’s discuss the properties of 6063 aluminum materials, which are widely seen around us. 6063 aluminum materials are made from alloys with the 6063 designation. 6063 belongs to the 6-series alloys and is an aluminum-magnesium-silicon alloy. The magnesium content ranges from 0.45% to 0.9%, and the silicon content is between 0.2% and 0.6%. Although the total alloy content is very low, it significantly alters the performance of aluminum. Silicon enhances the hardness of the aluminum alloy, while magnesium improves its corrosion resistance.
The hardness of 6063 aluminum materials ranges from 8 to 12 HW, with a tensile strength of ≥205 MPa, a proof stress of ≥170 MPa, and an elongation of ≥7%. These properties are considered moderate among 6-series aluminum alloys.
6063 aluminum materials have excellent corrosion resistance, and their antioxidant performance can be greatly enhanced through surface treatment. When used in harsh outdoor environments, their service life can reach more than 25 years.
6063 aluminum materials also have strong plasticity and good extrusion formability, so the 6063 designation is the primary choice for extruded profiles. Almost all architectural profiles and industrial aluminum profiles are made using 6063 aluminum materials.
