Embodiment

[0058] Hereinafter, examples of the present invention will be specifically described.

[0059] As a series of Example 1, the raw materials were prepared so as to have the composition shown in Table 1, manganese was fixed at 0.3%, the aluminum content and calcium content, and the ratio of Ca / Al were varied. Similarly, the series of Example 2 had the composition shown in Table 2, changed the aluminum content, calcium content, and manganese content, and changed the Ca / Al ratio. In the series of Example 2, the amount of strontium, mixed rare earth, silicon, and tin is contained.

[0060] The raw materials are then melted without flux in a gas melting furnace. Then, after keeping the temperature of the molten metal at 690° C., it was charged into a molding cavity of a die-casting mold of a 7.8 MN die-casting machine, and a casting (die-casting casting) was cast as a test piece. In addition, the compositions shown in Table 1 and Table 2 are target values.

Abstract

A magnesium alloy containing aluminum, manganese and calcium, characterized in that the magnesium alloy includes 6~12% by weight of aluminum, 0.1~1.5% by weight of manganese, a calcium / aluminum mass ratio being 0.55~1.0, and balance being magnesium and inevitable impurities.

Description

[0001] technology area [0002] The present invention relates to a magnesium alloy with excellent heat resistance and castability and its casting. Background technique [0003] Magnesium alloys have been used in industries such as the automobile industry to reduce weight. Its scope of application will be expanded in the future. It is considered that it is especially suitable for the parts around the engine where the weight reduction effect is obvious. However, engine peripheral parts and the like require high heat resistance, and development of magnesium alloys having excellent heat resistance has been demanded. Compared with the existing magnesium-aluminum alloys, magnesium-aluminum-silicon alloys, magnesium-aluminum-RE alloys, etc. have been developed to achieve higher heat resistance, but in terms of corrosion resistance, castability, and cost Not necessarily enough. For this purpose, magnesium-aluminum-calcium alloys have been developed that are excellent in heat resis...
