A creep-resistant magnesium alloy having creep resistance superior to AE42 alloy and having relatively high corrosion resistance. The magnesium alloy has superior castability without any generation of open cracks and is less expensive than AE42 alloy for production. The creep-resistant magnesium alloy is made from 1.5 to 4.0 mass % of Al, 0.5 to 1.8 mass % of Si, 0.05 to 0.6 mass % of RE, 0.005 to 1.5 mass % of Sr or Sb, and the reminder made from Mg and unavoidable impurities. Creep resistance is enhanced when 0.3 to 1.5 mass % of Ca is included. Further, corrosion resistance is enhanced when 0.1 to 0.4 mass % of Mn is included. |
