Sell niobium or have a specialist lot assessed
Do you have niobium or a lot that may contain niobium? Send photos, weight, dimensions, application and documentation. We assess whether this is sufficient for an initial commercial indication or whether further identification is needed.

Lot forms
Which niobium materials can you submit?
Niobium is less common as a standalone residual stream than many conventional metals. Material form, application, origin and documentation are therefore particularly important.
- Sheet, strip and foil
- Bar, wire and components
- Production residues
- Specialist components
- Traceable or sorted lots
Material & application
Niobium as a metal versus niobium as an alloying element
Niobium can occur as specialist material, but it is also used as an alloying element in complex alloys and steels. Detecting niobium in an analysis therefore does not automatically make a component pure niobium.
For an unknown lot, production or equipment origin, part numbers, certificates and previous analysis can be valuable in establishing a realistic classification.
Identification
Distinguishing niobium from tantalum and other specialist metals
Niobium can be part of complex alloys. A trade name or visual similarity does not guarantee composition. Material certificates, part numbers and analysis data are valuable.
Niobium and tantalum can look similar to a non-specialist. Reliable sorting therefore requires more than visual comparison; keep suspected material separate until sufficient information is available.
XRF as support for material identification
A handheld XRF analyser can provide an indicative elemental composition for many metals and alloys. This supports sorting and commercial assessment; where certified laboratory analysis is required, we discuss this in advance.

Estimated weight and postcode help assess logistics.
Add material information
Certificates, grade, origin and part numbers when available.
We assess the next step
We advise what information, analysis or logistics are required.
Valuation
What determines the value of niobium material?
For niobium, the actual nature of the stream matters more than a general market quote. Purity, application and traceability determine how a lot can be assessed.
Purity & type
Niobium and niobium-bearing alloys are not the same commercial stream.
Analysis & records
Certificates, part numbers and analysis data are particularly valuable for less common material.
Form
Sheet, wire, bar and components have different practical handling needs.
Mixing
Tantalum, steel or other alloys reduce clarity of the lot.
Lot size
Quantity and continuity influence the economic and logistics approach.
Available outlets
The market for specialist niobium material is more specific than for common metals.
Practical questions
Questions about niobium residual material
Are niobium and tantalum the same metal?
No. They are different elements and material streams, even though some forms can look similar.
Is a superalloy containing niobium niobium scrap?
Not automatically. The complete alloy composition determines how the material should be classified.
Can I submit components that may be niobium?
Yes. Send photos, weight, application and available documentation so we can determine the identification required.
Why is traceability especially useful for niobium?
Niobium is a specialist stream. Reliable origin and material records reduce the risk of incorrect classification.

Submit niobium or an unknown specialist lot
Send photos, dimensions, weight, origin and available technical information. Do not mix suspected niobium with other specialist metals before assessment.
