Insulating varnish systems:
>C3 varnish: organic insulation system, which considerably improves the stampability of the material
>C5 varnish: it has an excellent weldability and resistance to annealing, suitable for die casting
>Backlack varnish: the backlack technology is an innovative method to assemble the packs of electrical sheets. With a controlled chemical process, the laminations with this varnish come together in packs in a clean and compact way.

Cold rolled non-oriented electrical strip and sheet delivered in the fully processed state
(UNI EN 10106)
This type of electrical steel does not require an annealing treatment after the shearing phase, as it already has the required magnetic characteristics.
It complies with EN 10106 standard which defines the types of cold rolled non-oriented grain steel sheets and electrical strips having a thickness of 0.35 mm, 0.50 mm, 0.65 mm and 1.00 mm.
In particular, the standard provides general requirements, electrical properties, tolerances and technical characteristics as well as control procedures.
Cold rolled non-oriented electrical strip and sheet delivered in the semi processed state
(UNI EN 10341)
The semi-processed sheet is annealed by the customer to obtain specific electromagnetic properties.
The EN 10341 standard defines the types of sheets and electrical strips of non-alloy and non-grain alloyed steel, cold rolled and supplied in the semi-finished state (without final annealing), with a thickness of 0.50 mm and 0.65 mm.
It also provides general requirements, electrical properties, geometric characteristics, tolerances, technical characteristics and control procedures.
