Aluminum material is about one-third the weight of steel and offers excellent corrosion resistance, making it ideal for aerospace, automotive, and marine industries. It has high thermal conductivity, which benefits heat dissipation applications.

While it’s softer than steel, certain alloys like 7075 offer competitive strength. It’s easy to machine and can be anodized for added durability. Cost-wise, raw aluminum can be pricier per pound, but savings often come from reduced weight and easier machining. Many industries successfully replace steel with aluminum for improved performance and efficiency.
