  • Applications

    Aluminum (CAS 7429-90-5) is widely used in industry due to its light weight, strength, and excellent electrical and thermal conductivity; key application areas include electrical and thermal management (aluminum conductors, heat sinks, enclosures), packaging and consumer cans/foil, structural and transportation components (aluminum alloys in construction, aerospace, and automotive), surface treatment and coatings (anodized aluminum for corrosion resistance and decorative finishes), and household cookware and bakeware.
