It naturally develops a protective oxide layer when exposed to air, preventing rust.
It is an excellent conductor of heat and electricity, often used for power lines and heat sinks (roughly 60% as conductive as copper, but much lighter). aluminium
Heat-treatable, high strength, often used in aerospace. It naturally develops a protective oxide layer when
While pure aluminium is soft, alloys can be significantly strengthened (some to higher levels than steel). 2. Specialized Environmental Features but much lighter). Heat-treatable
Highly corrosion-resistant and conductive (e.g., food packaging).
Good all-purpose, moderate strength (e.g., cookware).
Strong, corrosion-resistant, common for structural, architectural, and automotive applications. 4. Common Applications
