Title:
ダイカスト鋳造可能な高熱伝導性マグネシウム合金およびその製造方法
Document Type and Number:
Japanese Patent JP7379675
Kind Code:
B2
Abstract:
The present invention relates to a die-castable highly thermally-conductive magnesium alloy and a production method therefor. The die-castable highly thermally-conductive magnesium alloy is 3.1–5.0 wt% La, 1.5–3.0 wt% Al, 0.1–0.5 wt% Zn, and 0.1–0.5 wt% Mn, the remainder being Mg and unavoidable impurity elements, the mass ratio of the Al content and the La content being 1:1.4–1:2.5. At 25°C, the die-castable highly thermally-conductive magnesium alloy has a thermal conductivity of over 105 W/(m·k), a yield strength of over 128 MPa, a tensile strength of over 220 MPa, and an elongation percentage of over 6% and is suitable for die-casting housings, such as for communication equipment and automobile components, that have high heat dissipation requirements.
