Abstract
The invention relates to a manganese-magnesium-aluminum alloy. The manganese-magnesium-aluminum alloy is composed of the following components in percentage by weight: 0.6-0.8% of Mn, 45-68% of Mg, 0.10-0.22% of Si, not larger than 0.03% of Cu, 0.005-0.05% of Zn, 0.001-0.003% of Ti, 0.15-0.40% of Fe and the balance of aluminum and inevitable impurities. By controlling the contents of the components, the alternating bending resistance, the thermal tensile strength, the mechanical strength and the like of the material are better than those of a traditional aluminum alloy, a uniform rough surface can be formed to improve the adhesiveness of a photosensitive material, and the manganese-magnesium-aluminum alloy fits for the ever-changing requirements of printing strength and width.
Description
technical field [0001] The invention relates to the field of aluminum alloy materials, in particular to an aluminum alloy used as a printing plate in a lithographic printing process, which can change the alternating bending resistance and thermal tensile strength. Background technique [0002] Today's advertising calls for larger and larger printing surfaces, so that the printing plate must be clamped in the printing unit not along the rolling direction, but transversely with respect to the rolling direction, which is very important for the printing plate against alternating bending In terms of performance, thermal tensile strength and roughness mechanical strength, higher requirements are put forward to achieve super large printing width, but the existing technology has defects in this regard. Contents of the invention [0003] The purpose of the present invention is to provide a more optimized manganese-magnesium-aluminum alloy formula, which has better alternating bendi...
