Micro-alloyed copper magnesium alloy

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...

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. Companies urgently need to adopt new alloy materials to curb the growing cost pressure.
