Applications of 7022 aluminum bar
Tool and Mold Manufacturing: 7022 aluminum rods are ideal for making molds for blow molding, thermoforming, and injection molding.
Aerospace: Due to their lightweight and high-strength properties, 7022 aluminum rods are widely used in aerospace structural components.
Military Technology: This alloy performs exceptionally well in military equipment, offering high resistance and corrosion resistance.
Construction Structures: 7022 aluminum rods are used in building structures that must withstand high loads.
Civilian Applications: In recent years, 7022 aluminum rods have increasingly been used to manufacture high-performance machinery and durable consumer goods.
Anodizing of 7022 aluminum bar
7022 aluminum rods can undergo anodizing treatment; however, due to their copper content, the anodizing effect may be inferior compared to other aluminum alloys (such as 6061).
For copper-containing aluminum alloys, the color and quality of the anodic film need to be adjusted based on specific processes.
Hard anodizing or special surface pre-treatments can also be selected to enhance the uniformity and corrosion resistance of the anodic layer.
