Welding rod auxiliary material - FeSi45 powder

45 Atomized Silicon Iron Powder (Ferrosilicon 45) is a spherical alloy powder prepared through high-pressure gas or centrifugal atomization technology. The silicon content is stable at 43-47%, and it features high purity, low oxygen content, and excellent fluidity. Compared to traditional crushed silicon iron powder, the atomization process makes the particles more uniform and the surface smoother, making it an ideal choice for powder metallurgy, welding materials, and other fields.

 Core Product Advantages

✅ Spherical particles, excellent fluidity

The atomization technology ensures that the powder is nearly spherical, with better fluidity than crushed powder.

✅ Low oxygen content (<0.5%), excellent sintering performance

The oxygen content is strictly controlled to avoid the formation of pores during sintering, thereby improving the density and mechanical strength of the finished product.

✅ The granularity can be customized, suitable for various processes.

Offer different specifications to meet customers' precise requirements.

✅ High silicon content (45%), enhancing alloy performance as an alloy additive, can significantly improve the hardness, wear resistance and corrosion resistance of the material.

Used in electrode and wire coatings, it improves the weld quality and enhances the crack resistance and corrosion resistance of the welded parts.
