Title:
ALUMINUM POWDER MIXTURE AND METHOD FOR PRODUCING ALUMINUM SINTERED BODY
Document Type and Number:
WIPO Patent Application WO/2022/138505
Kind Code:
A1
Abstract:
This aluminum powder mixture is obtained by mixing a starting material powder, which is composed of pure aluminum or an aluminum alloy, with from 5% by mass to 30% by mass of an aluminum alloy powder that has a lower melting point than the pure aluminum or the aluminum alloy. The aluminum alloy powder is composed of an aluminum alloy which has a composition that contains from 5% by mass to 20% by mass of Si and/or Cu, and from 0.2% by mass to 2.0% by mass of Mg, with the balance being made up of aluminum and unavoidable impurities. Consequently, sintering among the aluminum powders is accelerated, thereby enabling the achievement of an aluminum sintered body that has a higher density and a high electrical conductivity, while achieving a high thermal conductivity.
