III. Product Features
Feature | Description |
Lightweight & High Strength | Aluminum density is approx. 2.71g/cm³, only 1/3 of steel, significantly reducing structural weight while meeting strength requirements |
Excellent Corrosion Resistance | A dense oxide film naturally forms on the aluminum surface, providing good atmospheric corrosion resistance; 5xxx alloys are especially suitable for marine and humid environments |
Good Workability | Can be cut, stamped, bent, welded, riveted, drilled, etc., meeting various design and installation requirements |
Excellent Thermal & Electrical Conductivity | Aluminum's conductivity is second only to copper, making it an ideal material for power and heat exchange applications |
Attractive Appearance | Good metallic luster; can be anodized, painted, laminated, etc., for a variety of finishes |
Non-Magnetic | Aluminum is non-magnetic, suitable for electronics and instrument applications sensitive to magnetism |
Eco-Friendly & Recyclable | 100% recyclable; recycling energy is only 5% of primary production – a model of green materials |
Good Low-Temperature Performance | Aluminum shows no ductile-to-brittle transition at low temperatures and actually gains strength, suitable for cryogenic applications |
