Problems solved by technology

Among them, 6063 aluminum alloy belongs to the Al-Mg-Si series alloy, which has the characteristics of corrosion resistance, good electroplating performance, and oxidative coloring. In die-casting production, it is easy to cause the adhesion between the casting and the mold cavity, that is, the phenomenon of welding, which causes the mold to be strained, the casting lacks meat, and the yield of die-casting production is low; the ADC12 aluminum alloy is an Al-Si-Cu alloy, basically It is a die-casting aluminum alloy material regenerated from waste aluminum. The die-casting parts produced by ADC12 aluminum alloy have a low die-casting welding tendency and good process performance. Better meet the technical requirements for the use of car lamp holders

Abstract

The invention discloses an aluminum alloy material for a car light heat dissipation base and a preparation method of the aluminum alloy base, and belongs to the field of alloy casting. The aluminum alloy material comprises the following components in percentage by weight: 6.57-7.53% of Si, 0.41-0.47% of Fe, 0.035-0.041% of B, 0.051-0.102% of RE (rare earth), less than or equal to 0.15% of impurities and the balance of Al. The preparation method comprises the following steps: adding aluminum ingots and an aluminum-silicon intermediate alloy into a smelting furnace, heating, adding an aluminum-boron intermediate alloy when the temperature reaches 680 DEG C, adding an aluminum-iron intermediate alloy when the temperature reaches 720 DEG C, adding aluminum-RE intermediate alloy when the temperature reaches 740 DEG C, stirring fully, and when the intermediate alloys are completely melted down, slagging off and stirring fully to obtain an alloy melt; and refining the aluminum alloy melt, and then casting to obtain cast ingots, thereby obtaining the aluminum alloy material disclosed by the invention. The aluminum alloy material is low in die casting welding tendency, excellent in processability, high in thermal conductivity, and excellent in heat dissipation effect and can meet use requirements of the car light heat dissipation base.

Description

technical field [0001] The invention relates to an aluminum alloy material used for a car lamp heat dissipation base and a preparation method thereof, belonging to the field of alloy casting. Background technique [0002] The aluminum alloy die-casting of the heat dissipation base of the car lamp has a thin-walled deep-hole structure. There are streamlined heat dissipation grooves on the surface and screw holes on the bottom. The whole is in the shape of an irregular circular platform. Due to the serious heating of car lights under long-term working conditions, in order to ensure the service life of the lights, the casting requires that the die-casting alloy must have a certain thermal conductivity to ensure that the heat of the lights can be dissipated quickly; in addition, the die-casting process performance of the alloy must be good, Die-casting parts require precise dimensions and smooth surfaces without various die-casting defects. [0003] Currently, two types of alum...
