Abstract

The invention relates to a near co-crystallizing type casting aluminum silicon alloy material with high heat conductivity and a production method thereof. The alloy comprises the main components including Al and Si, and is characterized by also comprising at least one of Sr, Ca and B. During casting production, the temperature of a melt is maintained within a range of 600-850 DEG C, and the alloy melt is cast into a casting mould so as to be cast into a casting; when the casting product is subjected to heat treatment, the temperature rising velocity of the heat treatment process is lower than 20 DEG C / min, and the temperature is maintained to be 100-450 DEG C and maintained for 0.5-10 hours, and then, the casting is cooled or air-cooled along with a furnace.

Description

technical field [0001] The invention relates to a high thermal conductivity near-eutectic cast aluminum-silicon alloy material and a production method. Background technique [0002] With the rapid development of electronic information, communication, automobile and other industries, consumer electronics products, LED lighting equipment, communication base stations, auto parts, etc. have a trend of miniaturization and high integration. In particular, the development of the electronic communication industry is particularly rapid. At present, 4G communication technology has begun to be popularized, and 5G will also be commercialized in the next 3 to 5 years. The operating power and calorific value of communication equipment are getting higher and higher. The requirements for lightweight and reliability are also getting higher and higher. Studies have shown that for every 2°C increase in temperature, the life of electronic components will be reduced by 10%. The application of n...
