Aluminized Steel
Cascadia Metals supplies Aluminized Steel products for a host of end-use applications. Aluminized Steel is carbon steel coated, through the hot-dip process, with an aluminium-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminium coating, producing material with a unique combination of properties as compared to steel or aluminium alone.
Aluminized Steel can be made using a variety of processes, but the most effective process is hot dipping. The process of hot dipping starts by cleaning the steel, placing it in a bath of aluminium and silicone (Type 1) or aluminium only (Type 2), and then removing it, allowing the coated steel to air dry.
Type 1 and Type 2 Aluminized Steels can be used interchangeably in most applications. Cascadia Metals supplies Type 1 Aluminized Steel which contains approximately 90% aluminium and 10% silicon.
BENEFITS
Improved Yield Strength & Structural Durability – maintains strength yet easily formed
Corrosion Resistance – highly resistant, especially during exposure to salts
Lower Cost – as compared to other high-alloy steels
Heat Resistance – ideal for use where heat is involved
Heat Transfer & Reflectivity – reflects up to 80% of heat projected onto it while maintaining its strength
Our Type 1 Aluminized Steel meets ASTM A463 requirements.
So you can rest assured our product will meet all standard specifications per ASTM.
OPTIONS
Chemical Treatment
A chemical surface treatment is available which consists of a thin, invisible, corrosion inhibiting, inorganic, chemical film applied on both sides of the metallic coated surface. This film is applied at the metallic coating line by dipping the steel strip into a solution of corrosion inhibiting chemicals. The chemically treated surface is much more resistant to staining that typically occurs in humid conditions during storage or transportation.
END-USE APPLICATIONS
Aluminized Steel, due to its inherent benefits, is commonly used in manufacturing mufflers, fireplaces, incinerators, heat inductors as well as other applications where heat resistance is required. Other applications of Aluminized Steel include corrugated roofing and siding, grain bins, drying ovens, and air-conditioner condenser housings.
