: Higher efficiency and lower energy loss; preferred for high-performance or continuous-duty transformers.
: Used for high-frequency applications, though less common than steel for standard 50/60Hz EI power transformers.
Buying EI transformer cores requires balancing technical performance, material quality, and cost-effectiveness. These cores, named for their "E" and "I" shaped steel laminations, are the most common choice for power supplies, audio equipment, and industrial machinery due to their simple assembly and high reliability.
: Look for precision-cut sheets, typically between 0.3mm and 0.5mm . Thinner laminations (e.g., 0.35mm) are better at reducing eddy current losses and heat.
: Platforms like Alibaba and Tradeindia are ideal for bulk orders. You can find verified suppliers offering prices ranging from approximately $0.70 to $2.00 per kilogram for raw laminations.
: Ask for no-load current and dielectric strength data to confirm efficiency.
: EI cores allow for a small air gap between the E and I sections, which is useful for customizing inductors or audio output transformers. Where to Buy & Sourcing Options
