1050 and 1052 Aluminum Sheet for PS Plate

At present, 1050 aluminum sheet is a common base plate for making positive PS plate. However, during the usage, 1050 aluminum sheet meets some problems such as low strength, easy cracking and high energy consumption.

Another aluminum sheet, that is, 1052 aluminum sheet is put into use. Some users reflects that its performance is better than 1050 aluminum plate. 1052 alloy is formed by adding an appropriate amount of Mg to the 1050 alloy.

Due to the addition of Mg, the lattice constant of the matrix aluminum is distorted, resulting in metal strengthening. Therefore, the strength of the 1052 alloy is generally higher than that of the 1050 alloy.

The fibrous structure of the 1052 alloy in the cold rolled state is smaller and more uniform than that of the 1050 alloy, which is conducive to improving the uniformity of the grain structure. The average grain size of its annealed structure is also small, which is because a small amount of Mg can increase the crystallization temperature of pure aluminum.

Since the basic principle of a lithographic printing press is that the pattern portion absorbs ink, the blank portion repels the ink to absorb moisture. Therefore, the grain quality of PS plate for offset printing is an important index to evaluate the quality of PS plate.

From the above comparison, we can find that 1052 aluminum sheet is a little better than 1050 alloy. As for which to choose, it also depends on the your specific use. Haomei Aluminum has both two kinds. Welcome to inquire from us.
