foundry properties and fusion properties of magnesium alloy. Methods\ Combined with current smelting processes for producing magnesium alloy in the world
the principle and method of operation with or without flux cover have been introduced. Results and Conclusion\ The wide application of magnesium alloy depends on four factors: ① The design and development of products; ② Production cost; ③ Recovery of products and environmental protection; ④ The degree of urgent need for light equipment.
