A7072
A7072 is an aluminum alloy mainly alloyed with zinc (around 1%) and designed primarily for cladding on heat exchanger tubes and other applications that require good corrosion resistance. It has excellent corrosion resistance, good formability, and is often used as a cladding layer on high-strength core alloys (like 3003 or 7075) to enhance corrosion protection.
A7072 Aluminum Alloy is a specialized material designed for outstanding corrosion resistance and is commonly used as a cladding alloy in the aerospace and marine industries. Unlike other 7000-series alloys that focus primarily on ultra-high strength, A7072 is valued for its ability to protect high-strength core alloys, such as A7075 or A7475, from corrosion damage when bonded together. This makes it an excellent choice for applications where both durability and long service life are critical in challenging environments. A7072 also offers good weldability, formability, and chemical resistance, making it useful in piping, roofing, siding, and marine structures. Although its strength is lower compared to other 7000 alloys, its corrosion performance and protective properties make it indispensable as a surface layer material. At GD Prototyping, we provide A7072 aluminum solutions tailored to meet aerospace and industrial standards, ensuring optimal performance in both protective cladding and standalone applications.
