ADVANTAGES
- Very lightweight, about one-third the weight of steel, and very strong
- Exhibits a very high strength to weight ratio
- Very durable metal, yet easy to work with
- Offers a no-paint maintenance ability
- Easily fabricated, formed, welded, riveted or bolted
- Rust-proof
- Produces a highly reflective, attractive finish
- Resistant to corrosion and attack by most chemicals
- Forms aluminum oxide, one of the hardest man-made substances, when subjected to the commercial process of anodization
- Anodized aluminum has superior abrasion resistance
|
DISADVANTAGES
- Must be either powder coated or anodized to prevent oxidation
- Water-stains easily
- Proper storage is required to retain the protective finish, or the bright finish
- Can corrode quickly if suitable precautions against electrolysis are not maintained
- Welding requires specialized equipment and training
