Aluminum coil sheet a1050 h24 is a representative aluminum alloy name in aluminium purchasing. Generally just these words help suppliers to provide a targeted price. For the name indicates at least three aspects of specification: grade, temper, shape and even application scope, which further indicates sizes of the sheet. Here “a” stands for aluminium, “1050” aluminium content, “h” temper and “24” annealing state. In “hxx” state, the first digit 1 represents a simple work hardening state, which is suitable for the required strength without mechanical heat treatment. The second digit indicates the hardened state, the number 0 represents the annealing, that is, the soft state, 8 represents the hard state, 9 represents the superhard state, and the numbers 1 to 7 represent the state between 0 (annealing) and 8 (hard state).

In detail, The meanings of the figures in aluminum coil sheet a1050 h24 are as follows:

1. The first Arabic number 1 represents pure aluminum (pure aluminum is aluminum with an aluminum content of 99% or more, except for the beginning with 2-8, 2### is copper aluminum-magnesium alloy, 3### is aluminum manganese alloy, 4### is aluminum silicon alloy, 5### aluminum magnesium alloy, etc.)

2. The second Arabic number 0 means the original alloy, if it is 1, it means that the original alloy has been modified once, and 2 means that the original alloy has been modified twice.

3. Third and fourth, “50” two Arabic data in 1050 aluminum coil , the value of 99% of the pure aluminum content, and 50, the aluminum content of 99.50% aluminum, which is the standard 1060, the aluminum content is 99.60% pure aluminum and 1070 represent pure aluminum with an aluminum content of 99.70%. The latter two Arabic numerals in alloy aluminum have no special meaning, only used to identify different alloys in the same group, and the second position indicates the modification.

4. H in H24 indicates the state of work hardening. Some use H instead of H to indicate heat treatment. 24 indicates the processing technology for controlling physical properties such as hardness, except for 24, 12, 14, 16, 18, 22, 26 , 34, 36, etc., usually 4 is semi-hard state. 1060O state, 1060-H22, 1060-H24, 1060-H18 is a soft to hard arrangement.

The above is explanation to aluminum coil sheet a1050 h24. Hope it’s helpful.
