Aluminized Steel: The Best of Both Worlds

Aluminized steel combines the strengths of two key materials: aluminum and steel. Aluminum offers excellent corrosion resistance, while steel is renowned for its strength. However, each material has its drawbacks. Carbon steel lacks the chromium needed to prevent rust, and pure aluminum is weaker than steel. By merging the two, metallurgists have created aluminized steel, a superior material with a balance of both properties.

What is Aluminized Steel?

Aluminized steel is carbon steel coated with an aluminum-silicon alloy through hot-dipping. This process forms a strong bond between the steel base and the aluminum alloy coating, resulting in a material that benefits from both steel’s strength and aluminum’s surface qualities. Aluminized steel is also highly formable, making it easy to bend, fold, and shape without breaking.

Key Properties of Aluminized Steel

High-Temperature Resistance: The aluminum-silicon coating enables aluminized steel to withstand temperatures up to 900°F, far surpassing the 392°F limit of galvanized steel.
Low Thermal Expansion: Aluminized steel has a lower thermal expansion coefficient, reducing the likelihood of warping under heat compared to stainless steel.
Corrosion Resistance: The aluminum oxide layer formed during the coating process provides excellent protection against corrosion, making it more durable than both carbon steel and pure aluminum.

Aluminized steel is also cost-effective, making it a popular choice for various industrial applications.

Types of Aluminized Steel

There are two main types of aluminized steel, categorized by their coating composition:

Type 1: Contains 5-11% silicon and is typically used in equipment that requires extreme heat resistance, such as cooking appliances and heaters.
Type 2: Features a thicker, pure aluminum coating, making it ideal for cladding and insulation jacketing.

Common Applications of Aluminized Steel

Thanks to its high-temperature resistance and corrosion protection, aluminized steel is widely used in:

Incinerators, ovens, heaters, and barbeque grills.
Cooking equipment like baking pans and pots, where it remains rust-free and food-safe.
HVAC components and industrial piping that carry corrosive liquids.
