Ferroaluminum (Ferro Aluminium) Product Introduction

Ferroaluminum is a ferroalloy composed of aluminum and iron, serving as a highly effective composite deoxidizer and alloy additive in the steelmaking industry. We specialize in the international trade of ferroaluminum products, strictly adhering to the Chinese Industry Standard YB/T 4664-2018 Ferroaluminum, and can provide customized specifications according to customer requirements.

I. Product Introduction

Ferroaluminum (FeAl) is a ferroalloy consisting of iron and aluminum.The metal typically contains 40% to 60% aluminum.Ferroaluminum can also be supplied with varying aluminum content ranges, including 8–10% Al, 14–16% Al, 20–23% Al, 35–40% Al, or 45–50% Al.

The presence of iron in aluminum helps decrease casting defects, improves tensile strength, yield strength, hardness, and maintains strength at high temperatures.Ferroaluminum has a melting point ranging from 1160°C to 1250°C, depending on the aluminum content (1160°C at 60% Al; 1250°C at 40% Al).

Traditional steelmaking uses aluminum cakes or ingots directly added to molten steel, which is not only costly but also results in 70%–90% aluminum oxidation loss due to air and slag. Using ferroaluminum for deoxidation offers significant advantages: low burn-off, high recovery rate, and the ability to refine grain structure and improve steel impact toughness—making it an ideal choice for improving steel quality while reducing costs.

The first recorded usage of the word "ferroaluminum" was in 1887.

II. Product Grades and Chemical Composition

Ferroaluminum is available in multiple grades based on aluminum content and impurity levels. The following are the main grades and chemical compositions (referencing industry standards and steel mill technical requirements):

Note: Data above refer to industry standards and steel mill technical requirements.Ferroaluminum may also be supplied in other grades such as FeAl30 (30–35% Al) and FeAl40 (35–40% Al) per customer requirements.Special chemical composition requirements can be negotiated between supplier and buyer.
