Patent ID: 10192649

Abstract:
It is an objective of the invention to provide an Al alloy conductor exhibiting mechanical properties and heat resistance that are balanced at a higher level than conventional Al alloy conductors while having an electrical conductivity comparable to that of any conventional Al-based material. There is provided an Al alloy conductor formed of an Al alloy. The Al alloy has a chemical composition including Co of 0.1 mass % or more and 1 mass % or less, at least one of Sc of 0.1 mass % or more and 0.5 mass % or less and Zr of 0.2 mass % or more and 0.5 mass % or less, and the balance made up of Al and inevitable impurities. The Al alloy conductor has a matrix containing fine particles of a compound of at least one of the Sc and the Zr with the Al. The fine particles are dispersedly precipitated in the matrix.
