Spiegeleisen

Spiegeleisen

Spiegeleisen (German: "Spiegel"— mirror or specular; "Eisen"—iron) is a ferromanganese alloy containing approximately 15% manganese and small quantities of carbon and silicon. Historically, this was the standard form in which manganese was traded and used in steel making (see Bessemer process); today, manganese is usually traded and used in more concentrated form, 80% manganese content being typical.

Spiegeleisen is sometimes also referred to as "specular pig iron", "Spiegel iron", just "Spiegel", or "Bisalloy".
