Among the aluminum alloys used all over the world, Aluminum Angle Channel is very popular. Because they not only have good corrosion resistance, they also have excellent mechanical strength. For applications that require higher tensile strength, many suppliers recommend the use of Aluminum Angle Channel, and many architects prefer to strictly use aluminum angle steel for manufacturing. Although generally considered good corrosion resistance, aluminum angle steel exhibits excellent seawater resistance, making it suitable for marine applications. Some alloys did not increase in strength after heat treatment. For these alloys, the strength can be increased by processing unequal-leg aluminum angles, cold machining, and even strain hardening techniques.
