        Aluminum alloy enhances strength and durability over pure aluminum Many people think aluminum is just one thing. But pure aluminum and aluminum alloy are very different. Picking the wrong one can cause design failures, increased costs, or product recalls. Aluminum is a single element, while aluminum alloys are mixtures of aluminum with other metals.
