With a minimum content of 99.35%, Aluminum Alloy 1235 has become the most common aluminum foil alloy on the market today. Its fairly high aluminum content makes it an ideal alloy for a variety of industrial and food service markets. In the annealed condition, it is very ductile and easy to machine and form.
