PROBLEM TO BE SOLVED: To provide a magnesium alloy for damping which has excellent vibration damping performance and high strength, and a damping material. SOLUTION: The magnesium alloy contains 0.01 to 6 mass% of Zn and the balance Mg and inevitable impurities, and substantially contains no element of Y, La and Zr. By including a specific element and substantially excluding a specific element, the magnesium alloy has excellent damping performance with minimized internal friction, high hardness with high Vickers hardness, and excellent strength. The vibration damping performance can be further improved by including 0.01 to 4 mass% of Si. COPYRIGHT: (C)2012,JPO&INPIT |
