Types of Aluminum Alloy

These types of aluminum alloys enable engineers to select optimal materials based on strength, weight, and environmental requirements. From beverage cans (3000 series) to aircraft structures (2024/7075), each alloy type undergoes specific tempering processes (T3/T6/H32) to achieve desired mechanical characteristics.
