Conductivity
Aluminum is an excellent conductor of electricity and heat.

 

Corrosion Resistance
Aluminum reacts with the oxygen in the air to form an extremely thin layer of oxide. This layer is provides excellent corrosion protection. This layer repairs itself if it is damaged. Anodizing increases the thickness of the oxide layer, thereby improving the strength and value of the natural corrosion protection. A thickness between .015 and .025 mm is common for outside use. Aluminum is extremely durable in neutral and slightly acidic environments.

 

Jointing
Bonding, friction stir welding, fusion welding and taping are used for jointing.

 

Linear expansion
Aluminum has a relatively large linear expansion coefficient in comparison to other metals.

 

Malleability
Aluminum’s superior malleability is essential for extrusion. This property of aluminum is also exploited in the rolling of strips and foils, as well as other forming operations.

 

Machining
Aluminum is much easier to work with most machining methods – milling, cutting, drilling, bending, punching, etc. Another advantage of machining aluminum is the lower energy requirements.

 

Non-Magnetic Material
Aluminum is a non-magnetic material. Aluminum is often used in magnet X-ray devices because it will not interfere with magnetic fields.

 

Reflectivity
Aluminum reflects well both visible and radiated heat. Aluminum railing and decking material will stay cooler than wood or compost materials.

 

Electromagnetic Compatibility
Tight aluminum boxes effectively exclude electromagnetic radiation.

 

Strength
Unlike most steel grades, aluminum does not become brittle at low temperatures. Instead its strength increases.

 

Weight
With a density of about 169 pounds per cubic foot, aluminum is about one-third the density of steel. This means the same volume of aluminum will weigh one third as much as steel. This makes for lower shipping costs and easier installation and handling.

 

Availability
Aluminum is the third most common element in the Earth’s crust. Around 8% of the Earth’s crust consists of aluminum in the form of different minerals. So aluminum is one of the few metals for which the availability of raw materials is literally unlimited.
