Magneti Ljubljana

Permanent magnet manufacturer producing cast and sintered AlNiCo, sintered SmCo, and sintered and polymer-bonded NdFeB magnets, plus magnetic assemblies and (since 2023) 3D-printable bonded-magnet filament. Does not produce rare-earth alloy or metal itself; the company describes making its finished magnets and compounds from 'commercially available magnetic powders' and from bonded compounds either purchased from commercial suppliers or produced in-house from purchased powder. Ferrite is outside this profile's scope.

At a glance

Founded: 1951 — Founded 1951 for AlNiCo magnet production; joined the state-owned ISKRA group in 1962, left ISKRA in 1989, privatized in 1992, and formally renamed 'Magneti Ljubljana, d.d.' in 1995.

Capacity

This company manufactures magnets, so it has a capacity, but it does not publish one and no named third party has published a figure for it. An estimate of ours is exactly the kind of number this page exists not to print.

Narrative

Magneti Ljubljana is a Slovenian permanent-magnet manufacturer founded in 1951, with a continuous, single-purpose history in magnet production rather than a diversified industrial group. It spent 1962-1989 inside the state-owned ISKRA conglomerate before becoming independent and, in 1992, privatized into what became majority family ownership under Albert Erman. The company is one of a small number of remaining European producers spanning AlNiCo, SmCo, and NdFeB magnet technologies, and has publicized recycling/circular-economy work (direct reuse of waste SmCo and NdFeB magnets) alongside conventional sintered and bonded NdFeB production. It buys in alloy/magnetic powder feedstock rather than smelting or strip-casting its own rare-earth alloy, consistent with a finishing/magnet-maker rather than a vertically integrated alloy producer. It joined the Global Rare Earth Industry Association (REIA) in September 2023 and, as of that year, was participating as a magnet-materials supplier in the EU-funded HEFT electric-motor research project alongside GKN Automotive and other partners. No public capacity tonnage figures were found. The most recent public revenue and employee figures located (EUR 18.5 million, 244 employees) are for FY2021; no more recent statutory figures or evidence of insolvency, sale, or restructuring were found as of September 2026.

Where public sources disagree

The company name is easily confused with 'Magneti Marelli' (now Marelli), the large Italian automotive-components group historically making starters and alternators. These are unrelated companies with unrelated ownership and history; Magneti Ljubljana has, on all evidence found, always been a dedicated magnet-materials manufacturer (est. 1951) and not a starter/alternator maker or a broader automotive-parts conglomerate. This profile covers the Slovenian magnet company only.
It is not fully clear from public sources how much of Magneti Ljubljana's sintered NdFeB feedstock is purchased as finished alloy/strip versus purchased as powder and further processed in-house; the company's own website describes producing compounds from 'commercially available magnetic powders' and, for bonded magnets, using compounds 'supplied by commercial compound suppliers or produced in our company,' which does not unambiguously state the sintered-NdFeB alloy supply chain step by step.
No AJPES/statutory filing more recent than FY2021 (reported via the EY 2022 family-business profile) was located during this research; current (2025-2026) revenue, employee count, and any change in ownership structure since 2022 could not be independently confirmed from public sources.

How this page is sourced

Everything here comes from public sources — company filings, annual reports, exchange announcements, government releases and trade press. Every figure is linked to the document it came from and carries the date that document was published, because a capacity number without a date is not a fact, it is a rumor with a decimal point.

What is deliberately absent: material nonpublic information. I have spent more than two decades in this industry and a good deal of what I know about these companies I learned under NDA. Those obligations do not expire and they do not bend for a website. Nothing I have been told in confidence appears here in any form, and nothing on this page — or missing from it — should be read as a signal about what I know privately. I hold NDAs absolutely. It is the reason clients tell me things.

Judgment is the other thing left out on purpose. This page reports what has been published and who published it. Whether a target is credible, whether a ramp will hold, whether a capacity figure survives contact with the plant behind it — that is the work I do for clients, and it does not belong in a free reference page.

Where public sources disagree, I say so rather than picking a winner. Where a figure has not been published, the field says so rather than carrying an estimate. An empty field is information too.

Public filings tell you what a company has said. Whether it holds up is a different question, and the one I get hired to answer.
