Aluminum Plated Silicon Steel Coil

These coils feature a silicon steel core (Fe-Si alloy) with an aluminum plating layer for enhanced corrosion resistance and insulation. Available in thicknesses 0.18-0.5mm and widths up to 1200mm, they comply with GB/T 2521 and ASTM A677 standards. The aluminum plating (5-10μm) offers excellent solderability and electrical insulation, making them ideal for power transformers, inverter cores, and electric vehicle motors. We supply both grain-oriented (GO) and non-grain-oriented (NGO) types, with custom slitting and annealing services.
