What are the advantages of aluminium over cast iron?

Aluminium offers several advantages over cast iron, including its lighter weight, which makes it easier to handle and reduces energy consumption in transportation and application. It also has better corrosion resistance, allowing for longer lifespan in various environmental conditions. Additionally, aluminium has superior thermal and electrical conductivity, making it ideal for applications requiring efficient heat dissipation or electrical performance. Lastly, aluminium's malleability enables more complex shapes and designs compared to the rigidity of cast iron.
