Hi-u series flake Fe-Si-Al soft magnetic alloy electromagnetic wave absorbing powder is an innovative and advanced material designed for electromagnetic wave absorption applications. Composed of finely crafted flake particles made from Fe-Si-Al soft magnetic alloy, this powder exhibits exceptional properties that enable efficient electromagnetic wave absorption and attenuation.
The unique structure and composition of the Hi-u series powder contribute to its excellent performance in absorbing electromagnetic waves across a wide frequency range. Its specialized design allows it to effectively convert electromagnetic energy into heat, thereby reducing unwanted electromagnetic interference and enhancing signal quality.
With its superior soft magnetic properties, the Hi-u series powder offers outstanding magnetic permeability and low coercivity, ensuring optimal performance in various electromagnetic shielding and absorption scenarios. This versatile material finds applications in industries such as telecommunications, electronics, aerospace, and more, where the precise control of electromagnetic interactions is crucial.
1. Flake-shaped and flat morphology, with smooth powder edges and uniform particle size.
2. The permeability ur is high and it can be more than 200 for magnetic sheets made from the powders.
3. Suitable apparent density of the powder, suitable for shaping and processing, with relatively high final product density.
4. High saturation magnetic flux density (Bs) up to 1.1T.
Hi-u series can be mixed with polymer materials as raw materials and processed through various techniques such as calendaring, pressing, injection, extrusion, etc. to produce electromagnetic wave absorption components. The components are widely applied in terminals like cell phones, notebook, digital cameras, wireless routers, etc.
