Safety of Anodized Aluminum

Anodized Aluminum cookware offers users the lightweight and even heat distribution of aluminum with the strength and non-reactivity of other metal cookwares.

  1. Definition

    • According to the Aluminum Anodizer's Council, "A coating of aluminum oxide is grown from the aluminum by passing an electrical current through an acid electrolyte bath in which the aluminum is immersed."

    Process

    • The AAC explains that the process involves, "Anodizing is a process that converts aluminum to its oxide. The oxide is thicker than the aluminum that is consumed, which means the dimension of the anodized part changes."

    Chemistry

    • According to the AAC, the end chemical result is, "2/3 in 1/3 out; for example, a coating that is 0.6 mil thick will have consumed 0.4 mil of aluminum."

    Medical Concerns

    • There is a connection between aluminum and Alzheimer's disease. Furthermore, ingestion of aluminum can cause harm to the kidneys.

    Fun Fact

    • Aluminum is present in many products used daily including cake mixes, baking powder, toothpaste, sunscreen and cosmetics.
