Abstract

The invention discloses a preparing method of an alloy magnesium rod. The preparing method comprises following steps that copper, sodium and magnesium are added into an industrial furnace to be smelted; a magnesium ingot is added step by step until the component need is achieved, the mass percent of the copper is 0.1 to 2%, the mass percent of the sodium is 0.05 to 0.1%, and the balance is magnesium; a refining agent is added, and stirring refining is carried out; the refined alloy melt is subjected to heat preservation, and the temperature is controlled to range from 450 to 500 DEG C; and through pressurized extrusion, the alloy magnesium rod is obtained. The alloy magnesium rod obtained through the preparing method can be drawn into different lengths, diameters and shapes according to needs, the mechanical property, and corrosion resistance of the magnesium rod are equivalent to those of the brass rod, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of magnesium rod preparation, in particular to a copper-sodium-magnesium alloy magnesium rod. Background technique [0002] Brass rods are widely used in air-conditioning pipes, refrigerator pipes, oil pipes, water supply pipes and various mechanical supporting materials, but the price of copper remains high, resulting in a high cost of brass rods. Replacing brass rods with a less expensive metal rod has become a common challenge in the industry. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing magnesium alloy rods. The magnesium alloy rods obtained by the preparation method can be drawn into different lengths, diameters, and shapes according to requirements, and their mechanical properties and corrosion resistance are equivalent to those of brass rods. Dropped significantly. [0004] The present invention provides a kind of preparation method o...
