Title:
アルミニウム系クラッド型材の製造方法
Document Type and Number:
Japanese Patent JP6864922
Kind Code:
B2
Abstract:
Disclosed are a method of manufacturing an aluminum alloy clad section, and an aluminum alloy clad section manufactured by the method. The method includes preparing a composite powder by ball-milling aluminum powder and carbon nanotubes, preparing a billet from the composite powder, and subjecting the billet to direct extrusion using an extrusion die. The method is simple in procedure and uses simple equipment because it is based on direct extrusion which is suitable for mass production. Thus, the method is capable of producing a lightweight high-strength functional aluminum alloy clad section having a competitive advantage in terms of price over conventional aluminum alloy clad sections.
