AM50 AM50B Energy Saving Magnesium Metal Alloy INGOT AZ91A UNS M11911 Corrosion Resistant
AM50 AM50B Energy Saving Magnesium Metal Alloy INGOT AZ91A UNS M11911 Corrosion Resistant
WE54 is a high strength fully heat treatable magnesium based casting alloy for use at temperatures up to 300°C. The alloy develops high strength properties at elevated temperatures, without containing either silver or thorium.
APPLICATIONS
The excellent retention of properties at elevated temperatures and improved corrosion resistance will be of interest to designers of power systems, transmissions, missiles, high performance cars and other high technology applications. Prolonged use of this alloy (ie in excess of 1000 hours) at temperatures in the range 100°C–250°C may result in the loss of ductility. An alternative alloy is WE43.
