WebThe light weight and high strength of duralumin when compared to steel enabled its application in aircraft construction. Although the addition of copper improves strength, it also makes these alloys susceptible to corrosion. The electrical and heat conductivity of duralumin is less than that of pure aluminium and more than that of steel. WebIn fact, aluminum only has 60% of the thermal conductivity that copper does. That’s one point for copper. (Source: Engineer’s Edge) Aluminum vs. Copper: Weight If you look at the density of the two metals, you’ll notice that aluminum has only about 30% of the density of copper. That means significant weight savings. One point for aluminum!
Weboverload currents than copper-wound units. Pure aluminum has a coefficient of thermal expansion of 23.6 x 10-6/°C vs. copper’s 16.5 x 10-6/°C. This would lead users to believe that joints for aluminum conductors are prone to more fatigue from thermal cycling than copper—which is correct, however, manufacturers have connection methods to ...
