2024 aluminum is one alloy that is frequently used in the aerospace industry. The is a high-strength alloy perfect for projects requiring a high strength-to-weight ratio and excellent tiredness resistance. Together such, the is primarily uncovered in wing and also fuselage structures that frequently come under tension.
This alloy is often extruded, but it can also be uncovered in sheet and also plate form.
Here are Some General attributes of 2024
This alloy functions high strength, negative corrosion resistance and also weldability, great workability, and fair machinability. Download a PDF of its characteristics and material properties.
