Problems solved by technology

[0003] Now in order to improve the performance of aluminum, various raw materials are added to the aluminum liquid to form alloy materials. The performance of AL-Ca alloy is relatively prominent, but the existing AL-Ca alloy processing needs to be quenched, which increases the difficulty of processing. At the same time, AL -The tensile strength of Ca alloy is low, and there are certain limitations in use

Description

technical field [0001] The invention relates to the technical field of alloy preparation, in particular to an AL-Ca alloy and a manufacturing method thereof. Background technique [0002] Aluminum is a metal element, the element symbol is Al, and it is a silver-white light metal. Extensible. Commodities are often made into rods, sheets, foils, powders, ribbons and filaments. In moist air, it can form an oxide film that prevents metal corrosion. Aluminum powder can burn violently when heated in the air, and emit a dazzling white flame. Soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, insoluble in water. Relative density 2.70. Melting point 660 ℃. Boiling point 2327 ℃. [0003] Now in order to improve the performance of aluminum, various raw materials are added to the molten aluminum to form alloy materials. The performance of AL-Ca alloy is relatively prominent, but the existing AL-Ca alloy processing n...
