Title:
難燃性マグネシウム合金およびその製造方法
Document Type and Number:
Japanese Patent JP6814446
Kind Code:
B2
Abstract:
A flame-resistant magnesium alloy which suppresses occurrence of combustion of molten metal during alloy melting for casting and a method for producing the same are provided. By having a magnesium alloy which contains a specific amount of a specific element and also a specific amount of a rare earth element (RE) in a specific amount, an oxide film of a rare earth element (RE), which is dense, thin, and hardly breakable, is formed on an outermost surface of the molten metal. Specifically, provided is a flame-resistant magnesium alloy containing, in terms of % by mass, less than 9.0% of Ca, 0.5% or more but less than 5.7% of Al, 1.3% or less of Si, and 0.4% or more but less than 1.3% of a rare earth element with the remaining consisting of Mg and inevitable impurities and Al+8Ca ≥ 20.5%.
