Density, Strength-to-Weight Ratio, Manufacturability, etc.
|Material Properties||Less dense than steel||2.5 time denser than aluminum, Higher Modulus of Elasticity|
|Strength-to-Weight Ratio||Typically not as strong as steel, but 1/3 the weight||Steel is strong and is less likely to warp, deform, or bend under weight, force, or heat. 3x heavier|
|Manufacturability||Much more malleable than steel. Aluminum becomes stronger in cold weather||-High resistance to wear and abrasion, more difficult to handle, high hardness, harder to form than aluminum|
|Thermal Properties||Becomes soft above 400 degrees, Melting Point: 660 °C||Steel has much higher temperature capacities , Melting point: ~1500 °C|
