The 6061 aluminum plate is an alloy that has been made with silicon and magnesium. It is a readily machinable, weldable and formable grade of aluminum. It is the highest in its class of heat treated aluminums when it comes to corrosion resistance. This allows it to be used in heavy duty structures and marine environments. This product has a protective surface film that helps keep it from corroding. For further corrosion resistance, other coatings can be applied or anodizing can be performed. The electrical conductivity of this metal is 40 percent of copper. It is frequently used in the electrical field in the form of electrical fittings and connectors. Other applications for 6061 aluminum grades include marine fittings, marine components, fasteners, truck components, hinge pins, magneto parts, frames and structural components. It has a good weight-to-strength ratio, making it ideal for heavy duty structures.
The welding capability of this product is great, allowing any method of welding to be used. Annealing can be performed, which will put it in a state to be easily cold worked. Any methods of cold working can be used for stamping, drilling, bending, deep drawing, tapping and cutting. When annealing this metal, it’s recommended that it be placed in 775 degrees F for between two and three hours, followed by a steady drop in the temperature by 50 degrees each hour, until it is down to 500 degrees F. Air cooling should be allowed afterward. Other methods of heat treatment that can be used include solution heat treating, aging precipitation heat treating and hot working.
The available sizes for the 6061 aluminum plate are between .25 and 12 inches thick, between 48 and 96 inches wide and up to 240 inches long.
