7072 Aluminum sheets coil is a cold-treated forging alloy with high strength, far better than mild steel. 7072 is one of the commercial powerful alloys. Ordinary corrosion resistance, good mechanical properties and anode reaction. The finer grains make the deep drilling performance better, the tool wear resistance is enhanced, and the thread rolling is more distinctive.
●7072 Aluminum sheets coil characteristics and applications:
7072 aluminum alloy, American deformed aluminum and aluminum alloy. 7072 aluminum alloy has low electrode potential and is mainly used for anti-corrosion coatings, and also suitable for heat sinks of heat exchangers. 7072 aluminum alloy is used for air conditioner aluminum foil and ultra-thin strips.
