The invention discloses an AL-Ca alloy and a manufacturing method thereof, and relates to the technical field of alloy preparation. The AL-Ca alloy comprises the following raw materials in percentage by weight: 2.15-2.65% of Ca, 1.55-2.45% of Mg, 0.8-1.2% of Mn, 0.4-0.6% of Fe, 0.3-0.5% of Si, 0.3-0.5% of Zr, impurities and the balance of Al; the single impurity content is lower than 0.05%, and the total impurity content is not lower than 0.15%; the Al-Ca alloy is used for obtaining a microstructure with martensite as a main matrix and fine dispersed carbide as a reinforcement phase, the tensile strength is larger than Mpa, meanwhile, quenching treatment is not needed in the manufacturing method, the treatment difficulty is lowered, the practicability of the Al-Ca alloy is improved, meanwhile, sealing treatment can be conveniently conducted on a cover plate, gas leakage of a furnace body is prevented, and the working efficiency of the furnace body is ensured.

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...
