Aluminum bronze alloy material and production process thereof

Abstract

The invention provides an aluminum bronze alloy material and a production process thereof, and relates to the technical field of control systems. The aluminum bronze alloy material comprises the following material composition of, in percentage by mass, 11%-15% of aluminum, 4%-6% of iron, 1%-3% of manganese, 1.5%-4% of cobalt, 0.5%-1% of aluminum boron, 0.15% of a refiner, 0.25%-0.85% of copper rare earth and the balance copper. The production process comprises the following steps that S1, all the materials are prepared according to the proportion; S2, copper is put into a furnace to be melted, and then impurity removal, deoxidation and refining treatment are carried out; S3, aluminum, iron, manganese, cobalt, aluminum boron and copper rare earth are put into the furnace for alloying; and S4, the refiner is put into the furnace for secondary refining treatment, then casting and post-casting heat treatment are carried out, and the aluminum bronze alloy material is obtained. The aluminum bronze alloy material designed through the production process has excellent abrasive resistance and hardness, a die material made of the alloy can effectively prevent a die from scratching the surface of a product when the product is processed, and the reject ratio of the product and the polishing cost of the surface are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of alchemy technology, in particular to an aluminum bronze alloy material and a production process thereof. Background technique [0002] Aluminum bronze is a copper-based alloy with aluminum as the main alloying element. It is an aluminum bronze containing iron and manganese elements. It belongs to high-strength heat-resistant bronze. Aluminum bronze can be strengthened by heat treatment. Its strength is higher than that of tin bronze, and its high-temperature oxidation resistance is also higher. it is good. Aluminum bronze has high strength, hardness and wear resistance, and is often used to manufacture gear blanks, threads and other parts. Aluminum bronze has good corrosion resistance, so it can be used to manufacture corrosion-resistant parts, such as propellers, valves, etc. Aluminum bronze does not spark under impact and can be used to make non-sparking tool materials. It has excellent thermal condu...
