In the fields of high-performance alloys, magnetic materials, battery components, and powder metallurgy, the production of high-purity metals such as iron, manganese, and nickel requires precise process control and contamination-free environments. Traditional melting methods in open air cannot effectively prevent oxidation, elemental loss, or impurity introduction. Brother Furnace’s Vacuum Induction Melting (VIM) system provides a reliable and efficient solution to these challenges.

Challenges in Melting High-Purity Metals

When melting metals like Fe, Mn, and Ni, industrial and research users commonly encounter the following difficulties:

High susceptibility to oxidation: Iron and manganese oxidize rapidly at elevated temperatures, degrading purity.

Elemental volatility: Manganese and nickel tend to vaporize at high temperatures, leading to compositional deviations.

Limitations of conventional furnace environments: Standard induction furnaces often operate in atmospheric conditions, unsuitable for high-purity processing.

Strict purity and microstructure requirements: Especially in the preparation of functional or high-performance materials, impurity control and microstructure uniformity are critical.

Brother Furnace VIM Solution
