Aluminum alloy building formwork and preparation method thereof

Abstract

The invention discloses an aluminum alloy building formwork mainly comprising, by mass, 0.4%-1.0% of Si, 0.8%-1.3% of Mg, 0.05%-0.2% of Cu, 0.001%-0.15% of Mn, 0.2%-0.7% of Fe, less than or equal to 0.25% of Zn, 0.001%-0.1% of Cr, 0.03%-0.15% of Ti and the balance Al and inevitable impurities. The content of the inevitable impurities is less than or equal to 0.15%. Correspondingly, the invention further discloses a preparation method of the aluminum alloy building formwork. The aluminum alloy building formwork is excellent in mechanical property, the extrusion speed can reach 8-10 m / min, and the production efficiency is high.

Description

technical field

[0001] The invention relates to the technical field of aluminum alloys, in particular to an aluminum alloy building template and a preparation method thereof. Background technique

[0002] With the rapid development of urbanization in my country, building formwork, as an indispensable construction material and important machine tool for high-rise and super high-rise buildings, puts forward higher requirements for its service life, quality and safety assurance, and material recycling. Lightweight aluminum with a series of excellent properties is increasingly favored by the construction industry as an ideal "green building" material. There is a trend of replacing wood, plastic and steel with aluminum, so aluminum formwork should be used And born. The most widely used alloys for aluminum formwork are 6063, 6061, 6005 and 6082 alloys; among them, the most widely used is 6061 alloy formwork, but the extrusion speed of 6061 alloy formwork material is low (≤5m / min), ...
