Question #74553
Give the names of any two alloys of aluminium which have some amount of copper or magnesium. How are these more advantageous than pure aluminium?
Expert's answer
1 Duralumin is 95% aluminium, 4% copper, 0.5% magnesium, and 0.5% manganese - has increased strength and hardness compared to pure aluminum
2 Silumin.Aluminium-silicon alloys contain 3 to 25% silicon content, insignificant amount of impurities of Fe, Cu, Mn, Ca, Ti, Zn, and some others.
Al-Si alloys (silumins) have the best foundry properties.
