Pure aluminum, featuring good corrosion resistance and electrical conductivity, suitable for the electrical and chemical industries.
2xxx Series (e.g., 2011, 2024):
Copper alloys with high strength but lower corrosion resistance, commonly used in aerospace and military applications.
6xxx Series (e.g., 6061, 6063, 6082):
Silicon-magnesium alloys with moderate strength, easy to process and surface treat, widely used in construction, machinery, and transportation.
7xxx Series (e.g., 7075):
Zinc alloys with high strength, primarily used in aerospace and high-strength structural components, but with poor weldability.
Aluminum profiles come in various types, suitable for different industries and applications. Choosing the right aluminum profile can enhance product performance and lifespan while effectively reducing costs.
