Deformed aluminum and

Aluminum alloy

According to the provisions of GB/T16474-1996, the deformed aluminum and aluminum alloy grades are represented by a four-character system. The first, third and fourth digits of the grade are Arabic numerals, and the second digit is English capital letters (C, I, L, Except for 8 letters such as N, O, P, Q, and Z). The first digit indicates the group of aluminum and aluminum alloy, which is indicated by 1 to 9 as shown on the right; the second letter of the grade indicates the modification of pure aluminum or aluminum alloy, such as the second letter A is indicated as original Pure aluminum or original alloy, if it is B to Y other (in alphabetical order), it is a modification of the original pure aluminum or original alloy. The last two digits of the pure aluminum grade indicate the lowest aluminum mass fraction. When the minimum aluminum mass fraction is accurate to 0.01%, the last two digits are the two digits after the decimal point. The last two digits of the aluminum alloy grade are only used to distinguish different aluminum alloys in the same group.

Pure aluminum (Al content (mass fraction) is not

Less than 99.00%)
