1, Density comparison of different metals:
The density of aluminum alloy is 2.7g/dm3,
the density of copper is 8.9g/dm3, the density of iron is 7.9g/dm3,
and the density of stainless steel is 7.8g/dm3;
The density of aluminum is about one-third of theirs.
Items made of aluminum alloy are light in weight and can save transportation and processing costs.
2, When the temperature is low, the strength of aluminum alloy increases and it is not brittle, so it is an ideal material for low-temperature devices.
3, Polished aluminum has a light reflectivity of 70%.
Aluminum alloy also has good reflective properties for heat radiation and radio waves.
