JK-ALU Steel

JK-ALU is a flat carbon steel product with an aluminium silicon coating metal coating specifically tailored to protect against oxidation at high temperatures.

The main advantages of JK-ALU are:

  • Up to 480°C, JK-ALU reflects 80% of the incident radiation. This characteristic allows for example to accelerate the rise in temperature of an oven keeping the calories in a given volume, or, on the contrary, to facilitate cooling by directing their evacuation.
  • At room temperature, the mechanical characteristics of the JK-ALU are identical to those of the basic steel. At 480°C, despite a sensitive softening, JK-ALU’s strength is about ten times that aluminum.
  • The constituents of the non-passivated JK-ALU pose no health risk and can be put in contact with food. The lack of harmfulness of the product is certified by the reports of many specialized agencies.
  • JK-ALU has an excellent chemical corrosion resistance, although none of the constituents of the coating plays the sacrificial role toward the steel as does zinc in the case of galvanized sheet. Aluminum coating reacts instantly with oxygen to form a thin film of alumina Al2O3, very stable and insoluble, passivating the surface of the sheet. In case of alteration of the surface (scratch), this protection is reconstituted.
