Problems solved by technology

This kind of aluminum-magnesium alloy is often due to the original impurities or impurities introduced later in the production process, which greatly reduces the tensile performance and electrical conductivity of the aluminum-magnesium alloy wire, especially during the drawing process. Even cracks appear on the surface, which not only causes a serious waste of resources, but also brings incalculable losses to the manufacturer.
