Description
Technical Field
The invention belongs to the technical field of aluminum templates, and particularly relates to an aluminum alloy template die-casting material for buildings.
Background
The conventional aluminum template processing method comprises the steps of firstly extruding a section, then sawing the extruded section, welding a sealing plate and drilling. The process is relatively complex. In order to reduce the working procedures of processing the aluminum alloy template, the aluminum template is formed by adopting a die-casting mode. In the related art, an A380 alloy or an ADC10 alloy is generally adopted for die casting production, but an aluminum template product made of the alloy is brittle, the elongation of the die-cast product is usually about 2%, and the die-cast product is easy to break after being beaten in the process of use in a construction site.
Therefore, there is a need to provide a new aluminum alloy template die-casting material for construction to solve the above technical problems.

Preferably, the aluminum alloy template die-casting material for buildings comprises the following components in parts by weight: 0.75% of Cu; 5.5 percent of Si; 0.22 percent of Mg; 0.5 percent of Fe; 0.2 percent of Zn; 0.29 percent of Mn; 0.4 percent of Ni; 0.03 percent of Sn; and (3) the rest: and Al.

In the invention, the properties and the effects of the components are as follows:
(1) si: the castability is mainly determined for reducing the shrinkage and avoiding the tendency of heat cracking, and if Si is increased to more than 7.5% in a conventional manner, the castability is better but the brittleness is remarkably increased, so that the content of Si must be reduced.
(2) Cu: the increase of the content can improve the fluidity, tensile strength and hardness of the molten aluminum, but can reduce corrosion resistance and plasticity, and increase the hot cracking tendency. By greatly reducing the Cu content (the temperature during die casting needs to be increased), the possibility of hot cracking can be greatly reduced, and simultaneously, the strength and the hardness of the aluminum template are within an acceptable range according to the use characteristics of the aluminum template.
(3) Mg: when the content is kept between 0.2 and 0.35 percent, the strength and the corrosion resistance of the alloy can be improved.
(4) Fe: if the amount exceeds 0.9%, the fluidity is significantly lowered, but if the amount is less than 0.6%, the die-casting process is likely to cause severe die-sticking, which is not suitable for die-casting.
Compared with the prior art, the invention improves the elongation of the product by adjusting the alloy components of the die-casting raw materials on the premise of keeping better castability and pressure resistance, and ensures that the aluminum alloy template is not broken by beating in the process of using in a construction site. The method specifically comprises the following steps: the product made of the aluminum alloy template die-casting material for the building keeps good castability and pressure resistance, and is free from damage in repeated beating tests. The elongation of the product reaches more than 5 percent. Only the alloy components need to be adjusted, the die-casting process does not need to be adjusted, and compared with other methods for improving the elongation, the method is low in cost and good in castability and pressure resistance.
