SILICON-IRON (LAMINATION) STEEL
Silicon-Iron, also referred to as Electrical Steel, is available in thin strip and sheet and is used for laminations in transformers, inductors, motors and generators. Its advantages include high saturation magnetization with low coercivity resulting in low hysteresis loss. The presence of silicon in the composition results in increased electrical resistivity which reduces eddy current loss. Arnold's products span thicknesses of 0.001" to 0.007" thick (0.025 to 0.178 mm). These thinner gauges are even more effective in applications with switching frequencies greater than 400 Hz.

Grain Oriented Electrical Steel (GOES) is the preferred material for transformers and inductors. Arnold's thin gauge products are especially useful in high frequency, high efficiency devices where heat loss must be minimized and efficiency optimized.
Non-Grain Oriented Electrical Steel (NGOES) is used for rotating machinery such as motors and generators. Arnold's thin gauge products are called by the trade name ARNON^TM and have industry-leading low-loss characteristics.
