Aluminum

Aluminum is a kind of metal and is an element with atomic number 13 and element symbol AI.
Abbreviated as aluminum.

● Among metals, it has a small specific density, is light, and has good workability.
● Pure aluminum has low strength, but it can be strengthened by alloying it with other metals.
It is used in various products because it is lightweight, easy to process, and strong.
● It has excellent thermal conductivity and is also used as a heat dissipation material.
● It is easy to combine with oxygen and forms an oxide film on the surface, so it is hard to rust.
The surface treatment that artificially forms this film is called alumite.

● Welding is very difficult.
● Weak against metal fatigue.
