Aluminum Grades
Aluminum grades can demonstrate a wide variation of properties depending on their alloying elements and undergone heat treated conditions.
Aluminum grades exhibits ease of fabrication, good appearance, good corrosion resistance, high fracture toughness, good weldability, and high strength-to-weight ratio. Each aluminum grade is characterized by its excellent mechanical and chemical properties and the elements found in their composition. The selection of aluminum mainly depends on the intentions and applications necessary and working conditions. The intended application allows manufacturers and other material users to rank the characteristics and properties of each aluminum grade from least to most important. This somehow helps in narrowing down the lists of aluminum grades and their suitability in varying applications and treated conditions.
There are important factors to consider upon the selection of aluminum grades including weldability, workability, machinability, corrosion resistance, heat treating, and strength. These factors may greatly affect the performance of each aluminum grades upon each of their designated uses.
