Embodiment 1

[0016] In the microalloyed copper-magnesium alloy of the present invention, the weight percent of its components is: 0.05% to 0.15% of magnesium, 0.001% to 0.005% of phosphorus, 0.005% to 0.1% of CuY15 alloy, and the sum of other elements as impurities is not more than 0.15%. The amount is copper;

[0017] The above-mentioned CuY15 alloy is copper yttrium rare earth master alloy, and the content of yttrium element is 15%. The purpose of using copper-yttrium rare earth master alloy is to prevent the oxidation of yttrium element, reduce burning loss, and ensure the uniformity of yttrium element in the melt.

[0018] The microalloyed copper-magnesium alloy is made by melting in a vacuum furnace.

[0019] As a further improvement of the present invention, the weight percentages of the microalloyed copper-magnesium alloy components are: 0.07-0.13% magnesium, 0.002-0.004% phosphorus, 0.008-0.08% CuY15 alloy, and the sum of other elements as impurities does not exceed 0.12% %, the ...

Abstract

The invention relates to a micro-alloyed copper magnesium alloy. The micro-alloyed copper magnesium alloy comprises the following components in percentage by weight: 0.05-0.15% of magnesium, 0.001-0.005% of phosphor, 0.005-0.1% of CuY15 alloy, not larger than 0.15% of other elements serving as impurities, and the balance of copper. The micro-alloyed copper magnesium alloy is smelted in a vacuum furnace. The micro-alloyed copper magnesium alloy provided by the invention is low in manufacturing cost, high in conductivity, high in strength, high in ductility and capable of replacing a copper based silver alloy in practical application.

Description

technical field [0001] The invention relates to a microalloyed copper-magnesium alloy. Background technique [0002] Compared with red copper, copper-based silver alloy has the characteristics of higher anti-softening temperature, higher strength and elongation, and less loss of conductivity, so it is widely used in the field of commutators (commutators of micro-motors). The commutator industry is a labor-intensive industry. The shape of the product is simple. After simple stamping, the materials are basically selected and assembled by hand, which requires a large amount of labor. Labor costs and raw material costs account for 95% of the total cost of an enterprise, and labor costs are on the rise every year. Reducing raw material costs is the core of price wars among enterprises. However, silver is a rare and precious metal. In the past ten years, the price of silver has continued to rise, which has brought huge cost pressures to companies that produce commutators. Compani...
