For example, the 1xxx series alloys (e.g., 1100, 1050) are pure aluminum with a minimum aluminum content of 99%, while the 6xxx series (e.g., 6061, 6063) contain magnesium and silicon as the main alloying elements.<\/p>\n\n\n\n<p>The remaining three digits provide more specific information about the alloy composition, variations, and modifications.
