Silicon Iron Powder

Product Introduction

Low-silicon iron powder (especially the type with 14–16% Si content and 80–83% Fe content) is widely used as a heavy medium for flotation and separation of minerals such as gold, diamonds, fluorite, lithium, copper, scrap aluminum, and recycled aluminum. Its high density and magnetic properties facilitate effective separation of target minerals from impurities

Gravity medium for mineral processing

Low-silicon iron powder (especially the type with 14–16% Si content and 80–83% Fe content) is widely used as a heavy medium for flotation and separation of minerals such as gold, diamonds, fluorite, lithium, copper, scrap aluminum, and recycled aluminum. Its high density and magnetic properties facilitate effective separation of target minerals from impurities

 

Metal Powder Metallurgy

It can be used as raw material for manufacturing high-precision metal components, such as bearings and gears, and is particularly suitable for scenarios requiring high material purity and uniformity

 

Welding Material Accessories

As an additive in the flux coating of welding electrodes, it improves welding performance

 

Chemical and Reducing Agents

Used as a reducing agent or additive in specific chemical reactions

 

Magnetic and Electronic Materials

It can be used for manufacturing soft/hard magnetic materials, ferrites, inductors, etc., but such applications typically require extremely low silicon content (<0.5%), while industrial-grade low-silicon iron powder (Si≈15%) is generally unsuitable for this scenario
