AI Technical Summary

Problems solved by technology

However, due to the low absolute strength of magnesium alloys, poor deformation ability at room temperature, easy oxidation, combustion, and corrosion, etc., the wide application of magnesium alloys as structural materials is limited. At present, the application of magnesium alloys is far less than that of aluminum alloys.

Description

technical field [0001] The invention relates to the field of electric power information communication, in particular to a chromium boride-reinforced magnesium alloy wire for cables, a manufacturing method and application thereof. Background technique [0002] For a long time, in the cable industry, copper has always been the dominant conductor due to its superior electrical conductivity and heat transfer performance. However, due to the shortage of copper resources and the rapid growth of demand, the price of copper has risen sharply, making the consumer market of copper have been looking for A suitable replacement. [0003] As the lightest commercial metal engineering structural material, magnesium alloy is known as the "21st century" because of its light specific gravity, high specific strength and specific stiffness, strong damping and vibration reduction, excellent liquid forming performance and easy recycling. "Green structural materials" have broad commercial applicat...
