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

A kind of manganese magnalium

Technical field

Aluminum alloy materials of the present invention field, refers to a kind of aluminium alloy that is used as printing forme in lithography process that can change anti-alternating bending performance and hot-drawn intensity especially.

Background technology

Present advertising requires to have increasing print surface, thereby make printing forme not along rolling direction, but must laterally with respect to rolling direction, be clamped in printing device, this is just to the anti-alternating bending performance of printing forme and hot-drawn intensity and can anchor physical strength aspect, have higher requirement, to realize the printing width of super large, and there is defect in prior art to this.

Summary of the invention

The object of this invention is to provide the manganese magnalium formula of more optimizing, make it have better anti-alternating bending degree and hot-drawn intensity and uniform roughened surface, to adapt to the requirement of super large printing width.

The present invention is achieved by the following technical solutions:

A magnalium, its composition is by weight percentage:

Mn：0.6-0.8％， Mg：45-68％，

Si：0.10-0.22％， Cu：《0.03％，

Zn：0.005-0.05％， Ti：0.001-0.003％，

Fe:0.15-0.40%, surplus is aluminium and inevitable impurity.

Beneficial effect of the present invention

Manganese magnalium of the present invention, by controlling the content of each component, at the anti-alternating bending degree of material and the aspect such as hot-drawn intensity and physical strength, all aluminium alloy capability is more in the past superior, and can form uniform roughened surface, increased the tack of sensitive materials, adapted in printing intensity and width requirement with rapid changepl. never-ending changes and improvements.

Embodiment

A magnalium, its composition is by weight percentage:

Mn：0.6-0.8％， Mg：45-68％，

Si：0.10-0.22％， Cu：《0.03％，

Zn：0.005-0.05％， Ti：0.001-0.003％，

Fe:0.15-0.40%, surplus is aluminium and inevitable impurity.

Manganese is separated out as intermetallic compound in aluminium alloy, refinement the crystal grain of alloy, improved physical strength and the toughness of alloy.

Magnesium has stronger toughness and ductility, in solidification process, strengthen and separate out, effectively improved its degree of drawing, make it have laterally with respect to the extraordinary anti-alternating bending performance of rolling direction, the adding to also help of magnesium carry out surface treatment, and erosion resistance is improved.

The present invention has improved the content of silicon, with this, improve the anchor of aluminum alloy surface, make its sensitive layer in ensuing exposure overlay on enduringly on printing forme carrier on the way and the retentivity of tone, and the interpolation of silicon, iron also makes printing forme have enough physical strengths, prevented that printing forme from breaking in installation and moulding process.

The content <<0.03% of impurity copper, if exceeded, has reduced on the contrary the preservative property of alloy sheets, and the stain of printing is increased with the increase of copper content.

The content of iron, silicon can not surpass above value, will crooked end check lower than content, higher than content, will form inhomogeneous uneven surface.

Titanium plays the effect of grain refining in alloy, but its content is when high, in the coarsening process of aluminium sheet, can make plate face inhomogeneous and uneven.
