°F / °C

Aluminum is very light, very strong, extremely flexible and corrosion resistant because its surface is always covered in an extremely thin and yet very strong layer of oxide film. It’s a great electrical and heat conductor and forms alloys with practically all other metals. It is usually weldable, but porosity can be an issue, as well as cracking.
