About ferroalloys
Editorial · sourcedWhat are ferroalloys?
Ferroalloys are iron-based master alloys used to add a specific element to molten steel during refining. The three highest-volume ferroalloys are ferromanganese (FeMn), ferrochromium (FeCr) and ferronickel (FeNi) — each carrying its namesake metal in concentrations of 65-95%, plus iron as a balance. Steelmakers prefer ferroalloys over pure metal because (a) the iron content does not contaminate the melt, (b) the alloy form has a lower melting point than the pure refractory metal, and (c) handling and dosing are simpler. Other ferroalloys covered indirectly via the parent-metal page include ferrosilicon (FeSi, ~50% of Silicon demand), ferrovanadium, ferromolybdenum, ferrotitanium and ferroniobium.
How ferroalloys are priced
No ferroalloy has a regulated cleared-futures contract on a major exchange. Pricing is by benchmark assessment from Fastmarkets, Argus Media and S&P Global Platts, plus the Chinese domestic spot service SMM (Shanghai Metals Market). Annual benchmark contracts between major producers (Eramet, Glencore-Merafe, Outokumpu) and stainless steel mills also set reference prices. For ferrochromium specifically, the European quarterly benchmark — agreed each quarter between Glencore-Merafe and major European stainless mills — has historically been the most widely cited reference. USGS records ferrochromium US annual average prices (MCS 2026 Chromium): 2021 $1.50/lb · 2022 $3.19 · 2023 $2.55 · 2024 $1.76 · 2025e $1.60.
Where ferroalloys come from
Country-level global ferroalloy production data does not exist as a primary-source publication — USGS chapters track the underlying elements (Manganese, Chromium, Nickel), and downstream allocation among ferroalloy / metal / chemical end-uses is left to commercial providers. The most-cited primary-source proxy is the US import source structure published annually by USGS MCS:
- FeMn (2021-24 US imports): Malaysia 26%, Australia 16%, Norway 16%, South Africa 14%, other 28%.
- FeCr (2021-24 US imports, Cr content): South Africa 41%, Kazakhstan 24%, Russia 6%, Finland 5%, other 24%.
- FeNi: the bulk of global FeNi capacity (and NPI, the lower-grade variant) is concentrated in Indonesia at Tsingshan-anchored industrial parks (Morowali / IMIP, Weda Bay / IWIP). Indonesian nickel output rose ~13% in 2025 per USGS MCS 2026 Nickel.
Who produces ferroalloys
Each of the three ferroalloys has a distinct producer set:
- FeMn: Eramet (Norway: Sauda; Gabon: Moanda — global #1), South32 (Australia: TEMCO Tasmania; South Africa: Hotazel/Metalloys), Assmang, OM Holdings (Malaysia), Glencore (TIZIR Tyssedal Norway, JV with Eramet), Manganese Metal Company (South Africa).
- FeCr: Glencore-Merafe Chrome Venture (South Africa: Lion, Lydenburg, Rustenburg, Wonderkop, Boshoek), Samancor Chrome (South Africa), ERG / Kazchrome (Kazakhstan: Aksu, Aktobe), Outokumpu (Finland: Tornio + Kemi), Tharisa (South Africa).
- FeNi / NPI: Tsingshan (Indonesia: IMIP Morowali, IWIP Weda Bay — world's largest stainless-Ni complex), Eramet (New Caledonia: SLN Doniambo), Nickel Industries (Indonesia), Vale (Onça Puma Brazil; PT Vale Indonesia Sorowako), Anglo American (Barro Alto, Brazil).
What ferroalloys are used for
Ferroalloys are intermediate inputs to steelmaking — they are not consumed in finished products directly. The element shares of demand:
- FeMn — ~90% of global manganese consumption goes to steelmaking, primarily as FeMn and silicomanganese (SiMn). Mn is added to virtually every steel grade as a deoxidiser and to bind sulphur as MnS (improving hot-workability). US FeMn imports in 2025 were ~350 kt, SiMn ~310 kt (USGS MCS 2026 Manganese).
- FeCr — practically all chromium consumption in metallurgy goes to stainless steel (FeCr supplies the Cr content; minimum 10.5% Cr defines stainless). The global stainless-steel market is ~60 Mt/year, with China the leading producer (USGS MCS 2026 Chromium).
- FeNi / NPI — >85% of US nickel consumption goes to stainless steel and Ni-bearing alloys (USGS MCS 2026 Nickel). FeNi / NPI is the Class II Ni feed for the stainless route, while LME-deliverable Class I primary nickel (cathode, briquettes) is the feed for the battery-cathode and superalloy routes.
Key facts about ferroalloy supply
- Mn, Cr and Ni are all on the USGS 2025 Critical Minerals list. Mn and Cr have zero US domestic mine production — both are 100% net-import-reliant.
- Ferrochromium content classes (USGS): high-carbon FeCr (>4% C) for bulk stainless, medium-carbon (2-4% C), low-carbon (≤1% C) for specialty grades. Charge-grade FeCr is the highest-volume category.
- The International Chromium Development Association, International Manganese Institute and Nickel Institute publish industry statistics and methodology guidance for life-cycle and emissions reporting.
- Indonesian nickel/NPI capacity expansion is the largest single force reshaping the global ferroalloy and stainless market — Indonesian output grew ~13% in 2025 (USGS MCS 2026 Nickel). The same complex feeds the EV battery chain via HPAL nickel sulphate.
