NOVELTY - Graphene and copper and/or copper alloy mixed powder comprising 3-10 wt.% graphene and remainder of copper and/or copper alloy powder, is subjected to cold briquetting process, degassed under vacuum condition for 2-4 hours in quartz tube in the vacuum degree of 1x 10-3 Pa. The quartz tube is heated at 850-950 degrees C for 2-4 hours, cooled, heat preserved at 800-900 degrees C for 24-48 hours, and subjected to hot extrusion process in the squeeze ratio of 15:1-20:1 to obtain copper-based olefinic alloy. USE - Preparation of copper-based olefinic alloy (claimed). ADVANTAGE - The method efficiently and economically provides copper-based olefinic alloy by simple method with high productivity. DETAILED DESCRIPTION - Graphene dispersion solution is obtained by configuring solution, adding graphene into solution, placing in ultrasonic wave oscillator and stirring. Copper and/or copper alloy powder is added to obtained graphene monodisperse solution and milled in ball mill jar for 20-40 hours. The obtained mixed solution is baked at 50-60 degrees C and dried to obtain graphene and copper and/or copper alloy mixed powder comprising 3-10 wt.% graphene and remainder of copper and/or copper alloy powder. The resultant powder is subjected to cold briquetting process, degassed under vacuum condition for 2-4 hours in quartz tube in the vacuum degree of 1x 10-3 Pa. The quartz tube is heated at 850-950 degrees C for 2-4 hours, cooled, heat preserved at 800-900 degrees C for 24-48 hours, and subjected to hot extrusion process in the squeeze ratio of 15:1-20:1 to obtain copper-based olefinic alloy.
