About

A broker that carries the workload, not just the introduction.

Astraferra Metals is a UK-based broker for germanium and critical metals. We find the supply, verify it, and handle delivery — taking sourcing off a manufacturer's hands rather than just pointing them toward it.

Why we exist

Sourcing critical metal shouldn't be a full-time job for someone else.

Finding a credible producer, proving the material is genuine, and getting it through customs in one piece is specialist work — work most manufacturing teams don't have spare capacity for. Astraferra Metals exists to carry that work: we do the sourcing and the legwork, so the metal simply arrives, verified and ready.

Why the name

Iron of the stars.

Astraferra comes from two roots: ferrum, Latin for iron, and astra, Latin for stars. Before humans learned to smelt ore, the only iron they had access to fell from the sky — meteoric iron, found rather than made, worked by cultures across the world centuries before anyone could extract it from the ground. It's a fitting name for a business built around the same basic idea: the material you need doesn't always come from the obvious place, and finding it, proving it, and getting it to the people who need it is a skill in its own right.

Germanium is where that idea starts in practice. The same approach — find it, verify it, deliver it — is built to extend to whatever critical metal comes next.

How we work

Three jobs, done properly.

Sourcing

Direct relationships with producers of germanium and critical metals, built from the ground up rather than bought off a trading desk.

Verification

Every sample goes to an accredited third-party laboratory for independent testing before it's presented to a client.

Delivery

Specification, customs classification, insured logistics, and documentation, managed personally on every transaction.

Mahbub Chowdhury

Founder, Astraferra Metals

Mahbub founded Astraferra Metals after looking closely at how fragile the supply chain behind everyday infrared and electronic components really is — a handful of producers, concentrated in one place, with most manufacturers holding no real alternative. Astraferra Metals is the result: a UK-based broker built to find that alternative, prove it's genuine, and deliver it properly.

Where we're headed

Germanium first, critical minerals next.

We're starting deliberately narrow — one metal, done properly, with the relationships and verification process built to last. As that foundation proves itself, the same approach extends to other critical and rare metals the same manufacturers depend on. We can also step in as an alternative source alongside an existing supplier when that's genuinely what's needed — but finding you dependable primary supply is the main job.
