Aluminum and magnesium heat sinks were then tested at two different heater settings with air velocities of 0, 0.4, 1, 3, and 7 m/s (0, 79, 197, 590, and 1378 fpm). The results of these tests showed that for low air velocities (below 1 m/s or 197 fpm) the performance of magnesium …
2003/11/19· Magnesium alloy is usually touted as having a higher specific strength than aluminum alloy, but of course it depends somewhat on which alloys you pick. Although magnesium alloys have a considerably lower density, specific stiffness of magnesium alloys is about the same as aluminum alloys, so it''s not immediately obvious what the advantages would be from a vibration point of view, at least to …
Magnesium research and development efforts have not been as extensive as aluminum and steel alloy R&D, so magnesium has a limited alloy set compared to aluminum and steel. Magnesium alloys do not have the creep resistance of steel, which limits their use in higher temperature engine part appliions.
