Aluminum Alloy with Ultra-High Thermal Conductivity and Manufacturing Method Thereof

Abstract

A manufacturing method of aluminum alloy with ultra-high thermal conductivity, includes steps of: a crucible furnace being preheated up to 500° C. or higher; adding in pure aluminum ingots to smelt; refining and deslagging when the temperature of the molten aluminum reaches 720° C.; adding nickel to melt when the temperature raised to 750° C., and the smelting temperature is controlled at 750˜810° C., after completion of refining and deslagging; sampling and analyzing the composition after confirming that the nickel is melted completely after fully stirring; adding aluminum titanium carbon after the nickel composition being confirmed; stirring and confirming that the melting of aluminum titanium carbon is completed; degassing through a rotary degassing device, wherein the degassing process takes about 5 to 10 minutes; letting stand for about 10 minutes after the degassing completed; sampling and determining the composition, wherein the final composition determination must meet the prescribed conditions; and casting aluminum ingots.
