Micrometals – Global leader in iron powder cores
Micrometals, established in 1951, are committed to supplying high-quality iron powder cores that meet the needs of the electronics industry. Micrometals are an engineering-driven organisation, offering powder core solutions with the widest catalogue selection of materials, sizes and shapes, as well as the ability to quickly provide customised materials to suit specific application requirements. In addition to the standard core catalogue items, Micrometals are experienced in producing custom shapes and sizes.
Key benefits of iron powder as a core material
Iron powders’ distributed-air-gap properties makes this material particularly well suited to energy storage inductor projects and military, aerospace and motor applications. Micrometals’ materials offer low -current losses, good inductance stability and high permeability.
For power-conversion applications
Micrometals’ PC series are used as a core material in power conversion circuits. Its stability, frequency response and high power-handling capabilities make it ideal for use in power conversion applications. Iron powder is a cost-effective design alternative to alloy powder core materials. It can also can be used in place of ferrite and iron-alloy laminations requiring a gap.
Iron powder has been used as a core material in RF circuits for many years. It is typically used to produce high Q inductors from 50KHz to 500MHz and broadband transformers above 50MHz. It is the preferred core material due to its stability, high Q, frequency response and power-handling capabilities.
For high-temperature applications
The 200C series™ of materials is specifically designed for severer environment applications where cores are exposed to or generate elevated temperatures. These cost-competitive cores materials are not subject to thermal aging for operating temperatures up to 200°C.
Shapes – if you can imagine it, we can create it
Apart from the standard shapes (toroid and E-core), Micrometals have a vast experience and capability to design and produce all kinds of custom shapes, including:
Micrometals have in-house die, tool and press design/manufacturing, and can develop unique tools and presses, allowing us to offer tailored sizes – from super small to extremely large. We can also adjust the (magnetic) core properties by varying the pressure and/or direction of pressure.
