Ferroboron Alloy

Ferroboron is a core iron alloy composed of iron and boron, classified into low-carbon and medium-carbon grades based on carbon content. Its boron content typically ranges from 9% to 25%, with the remainder consisting of iron; trace impurities (including Si, Al, S, and P) are strictly controlled. It appears as grayish-black metal ingots, granules, or fine powder, is chemically stable at room temperature, and rarely oxidizes during storage.

Product Introduction

Products Description

Ferroboron alloy is a commonly used alloy additive in steel mills and foundries, primarily used to introduce boron into molten steel. Although the amount of boron added is small, it has a significant impact on the steel's hardenability, strength, and wear resistance. We have been manufacturing this product for many years, serving customers in industries such as alloy steel, automotive steel, tool steel, and amorphous strip. We can provide products with varying boron content and particle sizes to meet specific customer requirements.
