Machinability: the machinability of aluminum profiles is excellent. In all kinds of deformed aluminum alloy and cast aluminum alloy, as well as in all kinds of states that these alloys have after they are produced, the change of machining characteristics is quite large, which requires special machine tools or technologies. Formability: specific tensile strength, yield strength, ductility and corresponding work hardening rate control the change of allowable deformation. http://www.yanghe1al.com/industrial-aluminum-profile/
