Difference between aluminum and cast iron cabinets
1. Corrosion resistance and strength:
Aluminum has a thin oxide protective film and is not easy to be corroded.It is often used to make chemical reactors, medical equipment, refrigeration equipment, petroleum essence equipment, oil and gas pipelines, etc. aluminum.
2. Weight:
The specific gravity of aluminum is lighter than that of cast iron, the density of cast iron is 7.8g / cm3, and the density of cast aluminum is 2.7g / cm3. The upper aluminum shell has a larger advantage than the cast iron shell, and the strength of the cast iron is high.
Cast iron is usually in the attitude of 200-400MPa, but the weight of aluminum alloy is light. Many industries have replaced aluminum alloy with cast iron. However, cast iron still has its advantages and disadvantages. The abrasion resistance, plasticity, and toughness of iron are well summarized.
3. Volume:
For the same factors, aluminum is lighter.Aluminum structural strength is smaller than cast iron per unit volume, so the aluminum shell volume is larger than the cast iron shell at the same strength. With some downsides, the strength of cast aluminum is less than that of cast iron with equal volume.
