High-performance die-casting aluminum alloy, preparation method thereof and communication product

Abstract

The embodiment of the invention provides a die-casting aluminum alloy. The die-casting aluminum alloy comprises the following components of, in percentage by mass, 12.1%-12.9% of silicon, 0.1%-0.9% ofmanganese, 0.15%-1.0% of magnesium, 0.81-1.4% of iron, less than or equal to 0.2% of copper, and the balance aluminum and unavoidable impurities. The die-casting aluminum alloy has excellent formingperformance, heat conductivity, corrosion resistance and certain mechanical performance, the problems that the yield of die castings is low, the machine is seriously burnt due to products heating, corrosion occurs in the coastal environment, the mechanical performance is insufficient, consequently assembling is difficult or deformation is serious under the wind load condition can be avoided, and therefore, the delivery requirements of complex communication products in the global environment are met. The embodiment of the invention further provides a preparation method of the die-casting aluminum alloy and a communication product comprising the die-casting aluminum alloy.

Description

technical field

[0001] The invention relates to the field of aluminum alloy materials, in particular to a die-casting aluminum alloy, a preparation method thereof, and a communication product. Background technique

[0002] With the development of the communication industry, the reliability requirements for communication products are getting higher and higher. The increase in thermal power consumption of various chips also poses challenges to the heat dissipation performance of communication products. Communication products are often shipped regardless of region and need to adapt to the global weather environment. This requires that communication die castings need to be corrosion-resistant to seawater and acid rain atmospheres, have good heat dissipation performance and can adapt to changes in cold and heat shocks, and have certain mechanical properties to meet wind load fatigue. In order to meet the comprehensive performance requirements of communication die-casting parts,...
