When it comes to choosing a mailbox, two popular options are cast aluminum and cast iron. Both metal materials offer durability, but they have their strengths and weaknesses and we noted some of them in our main article.
As you will read next, the final decision will depend on the intended use, personal preferences, and the environmental conditions to which the mailbox will be subjected. There are a few factors to consider when deciding which mailbox is more durable: material and how much maintenance you plan to conduct.
Cast iron mailboxes
Cast iron mailboxes are known for their sturdiness and traditional look. With the proper care, they can withstand harsh weather conditions and last for many years without rusting or corroding. They are often coated with a rust-resistant finish, which gives them some extra protection against the elements.
Cast aluminum mailbox
The best cast aluminum mailbox is highly resistant to rust and corrosion thanks to its natural oxide layer, which provides a barrier against moisture and other elements. Cast aluminum mailboxes are also less likely to show scuffing and fading, making them a great option for homes located in damp climates.

Weight and strength
Cast iron mailboxes tend to be quite heavy, making them more difficult to install and move around. Cast aluminum ones, on the other hand, are lightweight yet sturdy. However, cast iron mailboxes are stronger.
Design differences
In terms of design, both cast aluminum and cast iron mailboxes come in a variety of styles. However, cast aluminum mailboxes tend to have more modern designs, while cast iron mailboxes often have more traditional designs.
Care
A cast iron mailbox will require more frequent maintenance to keep it looking its best. Iron is a ferrous metal which means that it contains… iron (ferrum is the Latin word for iron). An object that is made from cast iron when it comes into contact with moisture, can rust. On the flip side, cast aluminum is a non-ferrous metal and has a lot higher resistance to corrosion and rust.
Summary
In conclusion, both cast aluminum and cast iron mailboxes offer durability and rust resistance, but each has its own unique set of advantages and disadvantages. Cast iron mailboxes tend to be heavier and more traditional-looking, while cast aluminum mailboxes are lightweight and resistant to corrosion and fading.
