What is better carbon steel or aluminized steel?

Aluminized steel may be steel that might have been hot-dip coated on both sides with aluminium-silicon alloy. This process might assure a tight metallurgical bond between the steel sheet and its aluminium coating, possibly producing a material with a unique combination of properties possessed neither by steel nor by aluminium alone. Although stainless steel is the stronger of the two, aluminized steel has a greater electrostatic surface, and can therefore reflect heat better.
