Capalex Aluminium Extrusions


Aluminium Alloy 1050 is a popular aluminium for general sheet metal work where moderate strength is required. Also used in extrusions where high ductility and corrosion resistance is important. It generally gives a bright finish.


Alloy 1050 is known for its electrical conductivity and can be used for; automotive trim, chemical and food industry equipment, light reflectors and strips for heat exchangers.
