Abstract

The invention relates to a bracket, in particular to a shutter door positioning bracket, and belongs to the field of alloy materials. The shutter door positioning bracket is made of a magnesium alloy;the magnesium alloy specifically comprises the following components in percentage by mass: 7.5-8.0% of Al, 0.55-0.65% of Zn, 0.15-0.25% of Mn, 0.05-0.1% of Si, 0.5-0.8% of La, 0.8-1.2% of Nd, 0.6-0.85% of NiTi long fiber, and the balance of Mg; and an Al-Zn film layer with a thickness of 1.0-1.2 mm is expanded and permeated on the surface of the magnesium alloy. The Al-Zn film layer is prepared on the surface of the magnesium alloy through the surface expansion and permeation treatment; and a stable dispersion layer consisting of a surface alloy layer AlMg2Zn and a Mg-Al-Zn solid solution layer is formed to achieve a corrosion resisting effect on the shutter door positioning bracket.

Description

field of invention [0001] The invention relates to a bracket, in particular to a positioning bracket for a rolling shutter door, which belongs to the field of alloy materials. Background technique [0002] The rolling shutter door plays the same role as the wall, and it is composed of curtain panels, seat panels, guide rails, supports, reels, boxes, control boxes, rolling door machines, stoppers, door lintels and manual quick release switch devices, etc. Composed of components, the closing and opening operation of the rolling shutter door is simple and convenient. Compared with the ordinary iron door structure, it has the advantages of low cost and easy installation. With the continuous improvement of living standards and the continuous development of social technology, the existing market There have been various rolling shutter doors, which have been widely used; for example, for public places or houses such as commercial facades, garages, shopping malls, hospitals, factori...
