Description

technical field [0001] The invention relates to equipment for preparing high thermal conductivity aluminum alloy for die casting and a preparation method thereof. Background technique [0002] High-pressure casting molding technology is one of the most commonly used molding methods for aluminum and aluminum alloy castings, and is widely used in industries such as automobiles, communications, energy, and consumer electronics. Generally speaking, die casting aluminum alloy parts have the advantages of complex structure, thin wall, light weight, and easy recycling. Today, with the rapid development of new energy and communication technologies, the requirements for large-scale structure and functional integration have placed stringent requirements on advanced materials. In the past, the design of aluminum alloy materials was a two-dimensional optimization of the balance between high strength and high plasticity, that is, the product of strength and plasticity was maximized, ref...
