Sendust is an alloy of 6% aluminium, 9% silicon, and 85% iron. Core losses higher than MPP. Very low magnetostriction, makes low audio noise. Loses inductance with increasing temperature, unlike the other materials; can be exploited by combining with other materials as a composite core, for temperature compensation. Saturation flux of about 1 tesla. Good temperature stability. Used in switching power supplies, pulse and flyback transformers, in-line noise filters, swing chokes, and in filters in phase-fired controllers (e.g. dimmers) where low acoustic noise is important.

The Global Sendust Magnetics Powder Core Market was valued at USD 285.6 Million in 2022 and is projected to reach USD 412.3 Million by 2029, growing at a Compound Annual Growth Rate (CAGR) of 5.4% during the forecast period (2023–2029). This growth is being driven by the rising demand for energy-efficient power supplies in renewable energy systems, the expansion of electric vehicles and automotive electronics, and the increasing adoption of advanced magnetic components in consumer appliances and uninterruptible power supplies (UPS) across industrial and residential sectors.
