Description

technical field [0001] The invention belongs to the field of alloy manufacturing, and relates to an aluminum alloy and a preparation method thereof, in particular to a heat-resistant deformation aluminum alloy with a high melting point and a preparation method thereof. Background technique [0002] In the prior art, when some aluminum alloy doors and windows and curtain wall structures are exposed to the sun in summer, the surface temperature may reach above 70°C. After prolonged exposure to wind and sun, the deformation stress of the aluminum structure will increase, and a small number of aluminum alloy doors and windows will crack; The high-altitude curtain wall glass has fallen off, which brings hidden dangers to safety. The second is the aluminum alloy doors and windows. When they are exposed to fire, due to their poor heat resistance and severe deformation in a short period of time, it is difficult for indoor personnel to open and escape; , Improving the high-temperatu...
