Manganese alloys,
made to grade
We produce two bulk manganese ferro alloys — ferro manganese and silico manganese — in consistent, certified grades, sized to your furnace practice and packed for bulk dispatch.
Ferro Manganese
Manganese addition for strength, toughness and deoxidation across carbon and alloy steels.
Jump to specifications ↓Silico Manganese
Combined manganese and silicon in one addition — our highest-volume grade.
Jump to specifications ↓Ferro Manganese
Ferro manganese (FeMn) is the primary manganese addition in steelmaking. It raises strength, hardness, toughness and hardenability, while acting as a deoxidiser and desulphuriser in the melt. We supply it in both high-carbon and medium-carbon grades.
- Manganese alloying in carbon and low-alloy steels
- Deoxidation and desulphurisation of the melt
- Improving hardenability in structural and engineering steels
- Grey and ductile iron castings in foundries
| Grade | Mn | C (max) | Si (max) | P (max) | S (max) |
|---|---|---|---|---|---|
| HC FeMn — Standard | 70–75% | 7.5% | 2.0% | 0.35% | 0.05% |
| HC FeMn — Low Phos | 70–75% | 7.5% | 1.5% | 0.20% | 0.03% |
| MC FeMn | 75–85% | 1.5% | 1.5% | 0.30% | 0.03% |
Standard graded lumps at 10–50 mm and 10–80 mm. Other size fractions and fines available on request.
Loose in bulk, or in 1.0 / 1.25 / 1.5 MT jumbo (FIBC) bags — palletised or loaded as required.
Silico Manganese
Silico manganese (SiMn) delivers both manganese and silicon in a single addition, combining alloying and deoxidation in one charge. It is the workhorse of long- and flat-product steelmaking — and the grade we produce in the greatest volume.
- Combined deoxidation and alloying of carbon steels
- TMT bars, wire rod and other long products
- Flat products and general construction steel
- Feedstock for producing medium- and low-carbon ferro manganese
| Grade | Mn | Si | C (max) | P (max) | S (max) |
|---|---|---|---|---|---|
| SiMn 60/14 | 60% min | 14% min | 2.0% | 0.35% | 0.04% |
| SiMn 60/14 (3C) | 60% min | 14% min | 3.0% | 0.35% | 0.04% |
| SiMn 65/16 | 65% min | 16% min | 2.0% | 0.30% | 0.04% |
Standard graded lumps at 10–50 mm and 10–80 mm. Custom fractions and fines supplied to order.
Loose in bulk, or in 1.0 / 1.25 / 1.5 MT jumbo (FIBC) bags, loaded to suit your logistics.
