6 FT - 1 1/2" x 1/8" Anodized Aluminum Angle Made in USA by Randall Manufacturing part number 6 FT M-660 Clear Anodized Finish: Anodizing is a process that improves the properties of metals and other materials by creating a thin layer of oxide on their surface. This process can has many benefits, including: Wear resistance: The oxide layer makes metals more resistant to scratches and wear and corrosion. Aesthetics: Anodizing can make metals more suitable for painting and dyeing, allowing for a variety of colors and finishes. For example on this product the anodizing color choice is clear satin which creates a uniform clear clean look while mantaining the look of aluminum. Adhesion: Anodized surfaces provide better adhesion for paint primers and glues than bare metal. 6063 Alloy: Alloy 6063 offers very good corrosion resistance. It also offers good weldability, brazeability, and workability. And it provides good tensile strength and machinability. T-6 Temper: The T6 refers to the temper or degree of hardness. This grade has a good strength-to-weight ratio and is also heat-treatable. With great formability and weldability, it is used for engineering and structural applications, boats, furniture, and more. 6 FT - 1 1/2 X 1/8" Anodized Aluminum Angle 6063 Alloy T-6 temper Made in America by Randall Manufacturing Benefits of Anodized include rust resistance, easy to paint and clean, beautiful finish for inside or outside use and longer lasting than mill finish counterparts.
