C68700 Aluminum Brass Tube PDF
Products Description
Aluminum brass C68700 (UNS designation C68700) is a high-performance copper-zinc alloy that possesses excellent corrosion resistance and mechanical strength due to the addition of aluminum. This material belongs to the "aluminum brass" family, also known as "ARS alloy," and is widely used in marine engineering, chemical equipment, and the power industry. It combines the machinability of brass with the corrosion resistance of aluminum, making it an ideal alternative to traditional brass and bronze.
