Title:
ALUMINUM ALLOY MATERIAL, AND CONDUCTIVE MEMBER, BATTERY MEMBER, FASTENING PART, SPRING PART, AND STRUCTURAL PART USING ALUMINUM ALLOY MATERIAL
Document Type and Number:
WIPO Patent Application WO/2019/188452
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an aluminum alloy material having sufficient strength and workability to replace iron-based or copper-based metal materials. This aluminum alloy material contains at least one among 0.2-1.8 mass% of Mg, 0.2-2.0 mass% of Si, and 0.01-1.50 mass% of Fe, with the remainder comprising Al and inevitable impurities, and has a fibrous metal structure in which crystal grains extend in one direction. In a cross section parallel to said one direction, the average value of the dimensions of the crystal grains in a direction perpendicular to the longitudinal direction thereof is 400 nm or less, and the primary surface of the aluminum alloy material has a crystal orientation distribution in which the ratio H (K100/K111) of K100 to K111 is at least 0.17 as determined by the X-ray pole figure method, where K100 is the sum of the diffraction intensities resulting from crystals in which <100> is oriented in the longitudinal direction, and K111 is the sum of the diffraction intensities resulting from crystals in which <111> is oriented in the longitudinal direction.
