Abstract
Official abstract text for this publication.
An aluminum alloy casting material for heat conducting is provided, wherein the thermal conductivity is improved of an aluminum alloy casting material whereof the castability is improved by the addition of silicon where said invention is characterized by being an aluminum alloy casting material with excellent thermal conductivity, comprising 5-10.0% by mass of silicon, 0.1-0.5% by mass of magnesium and the remainder comprising aluminum and inevitable impurities, and whereon aging treatment has been performed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A manufacturing method of an aluminum alloy cast having a thermal conductivity of at least 160 W/(m*K), wherein the amount of Si in solid solution within an aluminum matrix is adjusted to 0.5-1.1% by mass, and an area ratio of crystallized products within a metal structure is adjusted to 5-8%, comprising: casting a molten aluminum alloy comprising 6.0-8.0% by mass of silicon, 0.2-0.5% by mass of magnesium, 0.6% by mass or less of iron, titanium and…
