Abstract

The invention discloses a copper-nickel-manganese-iron alloy, which comprises the following components in percentage by mass: 19 to 21 percent of Ni, 20 to 22 percent of Mn, 4 to 5 percent of Fe, 0 to 1.5 percent of Ti and the balance of Cu, wherein the total mass percentage of all components is 100 percent. A method for preparing the copper-nickel-manganese-iron alloy comprises the following steps: weighing materials of the alloy in mass percentage, and mixing Ni powder, Mn powder, Fe powder and Ti powder for 4 to 6 hours; filling the mixed alloy powders in a crucible, placing a copper rod in the mixed powder in the crucible, placing the crucible with the copper rod and the mixed powder in a vacuum high temperature sintering furnace to carry out smelting according to a smelting process and then obtaining an alloy body; and obtaining the copper-nickel-manganese-iron alloy by carrying out solution treatment and ageing treatment of the alloy body. The copper-nickel-manganese-iron alloy and the preparation method thereof solve the problem that the traditional copper-nickel-manganese-iron alloy cannot work normally in a high-temperature environment without producing structure change due to the thick and nonuniform dendrite, incompact structure and component segregation of the cast structure thereof.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and relates to a multi-component copper alloy material, in particular to a copper-nickel-manganese-iron alloy, and also relates to a preparation method of the copper-nickel-manganese-iron alloy. Background technique [0002] Copper and copper alloys have sufficient mechanical properties, due to a series of special properties such as good corrosion resistance, electrical and thermal conductivity, non-magnetic properties, and anti-fouling properties against microorganisms and algae in water, plus easy casting and plastic processing It is widely used in various electric welding electrodes, contacts of electrical engineering switches, collector rings of engines, armatures, rotors, empty frames of electric trains, etc. environment such as wires. Since the mid-20th century, it has become an important material for modern industry. [0003] The new copper-nickel-manganese-iron alloy formed...
