Abstract

The invention provides a copper alloy mold material and a preparation method thereof; the mold material comprises the raw materials by the mass percentage: 8-15% of aluminum, 1-2% of nickel, 4-7% of iron, 0.5-1% of manganese, 0.1-0.2% of boron, 0.1-0.2% of zinc, 0.02-0.04% of phosphorus, 0.01-0.02% of vanadium, 0.15-0.25% of titanium, 0.02-0.06% of silicon, 0.1-0.2% of chromium, 0.01-0.02% of germanium, and the balance copper. The mold material is prepared by smelting the prepared raw materials, pouring and carrying out heat treatment. The mold material has the advantages of high strength andhardness, good ductility and toughness and excellent wear resistance.

Description

technical field [0001] The invention belongs to the technical field of mold materials, and in particular relates to a copper alloy mold material and a preparation method thereof. Background technique [0002] In industrial production, molds are used for stamping, forging, extrusion, injection molding, blow molding and other methods to obtain the required products, which are called "industrial aircraft carriers". After the parts are produced by the mold, they have the advantages of high quality, high production efficiency, low cost, saving materials and energy, so the mold is widely used in many fields of industrial production as the main process equipment, and has become an important means and process of contemporary industrial production. Direction of development. According to the statistics of "National Basic Conditions of Mold Professional Factory", my country's molds have grown at an average rate of more than 15%, which is more than double the average value-added of d...
