Embodiment 1

[0009] Example 1: Put 800 kg of aluminum ingots into the furnace according to the weight ratio; add 130 kg of silicon and 3 kg of iron in sequence; when the furnace temperature rises to 780°C, add 12 kg of nickel, 15 kg of manganese, 38 kg of copper and Magnesium 2 kg; after smelting and stirring uniformly, the gas and impurities in the aluminum liquid are precipitated; the furnace is kept at 675°C; the cold chamber die-casting machine with three-stage injection is used for die-casting; the mold design cavity uses the center feed; the die-casting The formed aluminum alloy workpiece is placed in an oven for heat treatment: firstly adjust the oven temperature to 200°C, bake for 2.1 hours, then increase the oven temperature to 390°C, bake for 1 hour, and finally increase the oven temperature to 430°C, bake for 2.3 Hours, after 2.4 hours of heat preservation, open the oven and cool to room temperature naturally. The heat-resistant aluminum alloy parts made by heat treatment have go...

Embodiment 2

[0010] Example 2: a. Put 790 kilograms of aluminum ingots into a furnace for melting, b. Add 123 kg of silicon, 5 kg of iron and 0.5 kg of zinc in sequence. When the furnace temperature rises to 785°C, add 15 kg of nickel, 12 kg of manganese, 50 kg of copper and 1.5 kg of magnesium, followed by 1.8 kg of trace element chromium. 0.1 kg of zirconium, 0.4 kg of titanium, 0.7 kg of antimony; c. After smelting and stirring uniformly, the gas and impurities in the aluminum liquid are separated out, d. Keep the furnace constant at 680°C, e. Die casting using a cold chamber die casting machine with three-stage injection, f. Mold design cavity adopts center feeding, g. Put the die-casting aluminum alloy workpiece into an oven for heat treatment. First, adjust the oven temperature to 205°C, bake for 2.3 hours, then increase the oven temperature to 380°C, bake for 1.5 hours, and finally increase the oven temperature to 440°C, and bake After making it for 2.4 hours and keeping it warm ...

Abstract

The invention discloses a high-temperature resistant aluminium alloy and a preparation method thereof. The high-temperature resistant aluminium alloy comprises 75.0-82.0 wt% of Al, 11.0-14.0wt% of Si, 3.0-7.0wt% of Cu, 0.9-1.9wt% of Mn, 0-0.5wt% of Fe, 0.8-2.1wt% of Ni, 0-0.25wt% of Mg, 0-0.1wt% of Zn, and 0-0.50 wt% of impurities. The preparation method comprises the following steps: melting, charging, stirring for precipitation, keeping a constant temperature, casting, feeding, conducting heat treatment, and baking. According to the invention, the problem that conventional aluminium alloy is easy to foam, deform, and the like in the case of high temperature can be effectively solved, the formula is reasonable, and the preparation method is simple.
