Fabricating method of dispersion reinforced Cu-Alumina alloys by selective internal oxidation and Cu-Alumina alloys manufactured by using the same

摘要

The present invention a) Cu-Al alloy powder is a step of mixing the powder with an oxidizing agent in the Al ₂ O ₃ particles are uniformly mixed with Cu powder;; b) wherein a) the powder mixture obtained in step to an internal oxidation process in a vacuum atmosphere to form a Cu-Al ₂ O ₃ alloy powder;; c) a step of reducing the internal oxide CuAl ₂ O ₃ alloy powder to remove the complex oxide made in the form of CuAl ₂ O ₄ CuAlO ₂ or by producing a CuAl ₂ O ₃ alloy billet;; d) degassing step of heating the composite oxide are removed Cu-Al ₂ O ₃ alloy billet in a vacuum atmosphere to remove the gaseous material contained in the alloy billet; And; e) a method for producing the degassing treatment of Cu-Al ₂ O ₃ alloy, Cu-Al ₂ O ₃ alloy, which comprises the steps of hot extruding a billet. Cu-Al ₂ O ₃ alloy of the present invention can develop a high electrical conductivity and is excellent in high temperature properties, electronics or essential contact points and an electrode material for welding automation of the vehicle production line.
