The following table compares aluminium and steel casting properties.
1. Strength
Steel is generally stronger than aluminium. However, steel is not the strongest metal. If a product requires enough strength, steel is a good choice. It can be used in a variety of applications and industries. Compared to steel, aluminium is also strong but appears inferior.
2. Weight
Steel is generally stronger than aluminium. However, steel is not the strongest metal. If a product requires enough strength, steel is a good choice. It can be used in a variety of applications and industries. Compared to steel, aluminium is also strong but appears inferior.
3. Corrosion Resistant
Despite its corrosion resistance, steel is more prone to rusting than aluminium. Because of this, aluminium is preferred for products used in moist or wet environments. Various kinds of steel exhibit varying levels of corrosion resistance. For example, carbon steel is prone to rusting easily. Steel such as stainless steel offers good corrosion resistance. For rust-free products, aluminium casting is an excellent choice.
4. Cost
Depending on the type of casting, the cost may vary. A steel or aluminium casting can be very expensive, especially if they were made of high-quality alloys. There may be differences in cost based on the type of product made, quality, and brand or manufacturer.
5. Heat Strength
Compared to steel castings, aluminium castings have a low heat strength. Aluminium melts at low temperatures, so it can be used for both creating products and for modifying them. However, if the product will be used in a high-temperature environment, steel casting is recommended.
