Atomized ferrosilicon powder is generally made from ferrosilicon with a silicon content of about 45% by water atomization. Compared with ordinary ground ferrosilicon powder, its particle size is smaller and more suitable for welding and other processes.

Atomized ferrosilicon powder is often used as an auxiliary material for welding coatings and as a deoxidizer in welding. The addition of atomized ferrosilicon powder helps to improve the deoxidising properties of the electrode and reduce the amount of oxygen in the weld. Atomized ferrosilicon powder is usually used as an auxiliary material for welding coatings, and is generally used as a deoxidizing agent in welding.
