Abstract
This invention provides aluminum alloy with ultra-high thermal conductivity, wherein the weight percentage of the composition: nickel: 2˜5%, carbon: 0.1˜0.5%, titanium: 0.01˜0.2%, iron: <0.1%, silicon: <0.1%, the metal components including copper, zinc, manganese, magnesium, chromium, lead, and tin is respectively <0.01%, M is another element with a content being limited to less than 0.005%, and the balance is aluminum; wherein the steps of the manufacturing method: a crucible furnace heated up to 500° C. or higher; adding pure aluminum ingots to smelt, refining and deslagging at 720° C., adding the nickel and stirring at temperature range between 750˜810° C., sampling and analyzing the composition after melting is completed and confirmed, confirming whether the melting is completely after adding aluminum titanium carbon and stirring; degassing through a rotary degassing device; letting stand for 10 minutes; sampling and determining the composition, and casting aluminum ingots.
