Description

Alusi® is a flat carbon steel product coated on both sides with an aluminium-silicon alloy. The coating is composed of 90% aluminium and 10% silicon and is applied by means of a continuous hot dip galvanising process. Alusi® is available in a wide range of steel grades: steels for cold forming and deep drawing applications, and structural steels.

Alusi® is particularly suitable for applications requiring high resistance to oxidation at high temperatures. Up to 450°C, the top surface of the Alusi® coating does not alter and its thermal and light reflectivity remains at 80%, which is an important requirement for thermal shielding applications. The presence of silicon allows the coating to be used at temperatures as high as 650°C without flaking.

A passivating layer of aluminium oxide is formed instantly in contact with the oxygen present in air. Since this passivation protection renews itself naturally when damaged (scratches), the coating offers excellent resistance to corrosion and chemical attacks.

Application areas

Because Alusi® can resist high temperatures, it is particularly suitable for use in thermal shielding. However, Alusi® also has many other applications:

  • General industry: exhaust systems, thermal shields, heating equipment, boilers, ducts, fume exhaust pipes, heat exchangers, industrial ovens etc
  • Building: fire doors etc
  • Domestic appliances: ovens, deep fryers, toasters, barbecues etc

    Alusi® can be supplied oiled and/or passivated, or with an Easyfilm® thin organic coating (please see data sheet E80 for the specific properties of Easyfilm®).

    Under certain conditions, Alusi® is suitable for food contact, as specified in the Regulation (EC) No. 1935/2004 and French standard NF A 36-712-2. Please contact us for further information on this subject.

    Recommendations for use


    Alusi® must be transported and stored in a sheltered, moisture-free environment.

    The forming and joining techniques currently used for uncoated steel are also suitable for Alusi®.

    Alusi® coated steel can be welded using various types of resistance welding processes (spot, seam, butt welding). TIG, MIG, MAG, High Frequency Induction welding and laser welding are also suitable. When supplied oiled, Alusi® needs degreasing and surface treatment before painting.

    Alusi® coated with an Easyfilm® thin organic coating can be painted directly, without any prior surface treatment. However, the paint must be compatible with the Easyfilm® resin.
