Warning: The Dangers of Closed Containers in Aluminum Scrap

Many billet makers, extruders, and sheet mills have specifications that prohibit closed containers (such as used beverage cans or fire extinguishers) from being in acceptable scrap packages.

Mixing water or other contaminants with molten aluminum can cause explosions. Explosions can also occur in the aluminum scrap re-melting process due to moisture and contamination in scrap. – (See more on the Aluminum Association’s website). When placed in a furnace, the moisture inside a can or canister expands rapidly as it turns from liquid into gas at the high furnace temperature. These explosions range widely in violence and can result in injury or death as well as destruction of equipment and plant facilities. We encourage all scrap metal dealers to keep used beverage containers and other such closed containers out of their mill grade aluminum packages.

More information can be found on the Aluminum Association’s website.
