Aluminum alloy die-casting door panel and manufacturing method thereof

Abstract

The invention belongs to the field of machining of alloy materials and discloses an aluminum alloy pressure-cast door plank. The aluminum alloy pressure-cast door plank is prepared from the following raw materials in percentage by weight: 4.1%-4.3% of magnesium, 1.8%-2.1% of manganese, 0.8%-0.9% of zinc, 0.6%-0.7% of copper, 0.3%-0.4% of nickel, 0.1%-0.2% of white graphite, 0.04-0.05% of cerium, 0.04%-0.05% of yttrium, 0.02%-0.03% of samarium, 0.01%-0.02% of silicon dioxide and the balance of aluminum. The aluminum alloy pressure-cast door plank is high in mechanical strength, can resist corrosion and is unlikely to be oxidized and change color; the preparation method is simple, feasible and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the field of alloy material processing, and in particular relates to an aluminum alloy die-casting door panel and a manufacturing method thereof. Background technique [0002] Aluminum alloy door panels refer to doors made of aluminum alloy extruded profiles as frames, stiles, and fan materials. They are called aluminum alloy doors, or aluminum doors for short. Including aluminum-wood composite doors, aluminum-plastic composite doors for short, which use aluminum alloy as the base material of the force-bearing rods (the rods that bear and transmit their own weight and load) and wood and plastic composite doors. Among the vast majority of existing buildings in our country, more than 90% are high-energy-consuming buildings. In high-energy-consuming buildings, doors and windows account for nearly half of the energy consumption. As analyzed by industry insiders, the key to energy saving in buildings is the energy saving of doors ...

AI Technical Summary

Problems solved by technology

However, the aluminum and magnesium alloy castings produced by die-casting have many internal pores, and cannot be subjected to solution heat treatment or welding, nor can they be subjected to excessive machining

[0004] At present, aluminum alloy door panels mainly have the following defects, such as easy discoloration, poor corrosion resistance, insufficient mechanical strength, uneven pores, complicated manufacturing methods, and high industrial energy consumption.
