Copper Powder 2N to 7N — Trade Inquiries
High-purity copper powder inquiries for industrial buyers, from 99% (2N) to 99.99999% (7N). Tell us the grade, form and quantity you need and we confirm in writing what is actually available.
- Inquiries handled across the range from 99% (2N) to 99.99999% (7N)
- Bonded storage at Zurich Airport — no duties or VAT in bond, quantities unrestricted
- Lot documentation and analysis scope confirmed in writing, case by case
- B2B only: every inquiry is screened before it is forwarded
How we proceed
- You send a written inquiry — company, phone number, quantity, grade or specification, application.
- We screen it: business to business only. Incomplete or irrelevant inquiries are not forwarded — too many frauds, too much wasted time. We are deliberately selective: a handful of serious B2B inquiries matters more to us than volume.
- Relevant inquiries go directly to the operating company holding the material in custody — no brokers, direct to direct.
- You receive a written answer, usually within one business day.
- If your inquiry passes screening and is of interest, we phone you directly to take it forward — qualified buyers get a call, not a form letter.
Send a written inquiry
Serious trade inquiries only. Write from your company address and state grade, quantity and application.
Copper powder grades, 2N to 7N
Each grade has its own reference page explaining what that purity level means, which impurities matter and how it is normally analysed. Tell us the grade you need, or describe your process, and availability is confirmed for your case.
| Grade | Typical use |
|---|---|
| 99% (2N) | Friction materials, brazing pastes, bulk metallurgy |
| 99.9% (3N) | Powder metallurgy, conductive fillers, MIM |
| 99.99% (4N) | Additive manufacturing, conductive inks |
| 99.999% (5N) | Sputtering targets, electroplating chemistry |
| 99.9999% (6N) | Semiconductor interconnect, ultra-high purity PVD |
| 99.99999% (7N) | Research quantities only — zone-refined |
High-security bonded storage — Zurich Airport
Stock is held in high-security warehouses inside the free-trade zone at Zurich Airport, under customs supervision and monitored by dedicated security personnel. No import duties or VAT are charged while material stays in bond, access can be arranged by appointment, and quantities are not a constraint.
Logistics — air, sea, land and express
Located directly at the airport, stock is checked in and dispatched quickly. Air freight, overseas shipping, land transport and express deliveries are organised in-house, and container or palletised cargo is handled on site without unnecessary steps.
Quantities
From a qualification quantity for process trials to recurring tonnage call-offs, quantities are not a limiting factor. The grade, form and documentation that apply to your lot are confirmed in writing.
Documentation
Lot documentation — certificate of analysis, custody and inspection paperwork, safety data sheet and customs documents — exists for the material and its scope is confirmed for your lot in writing. Nothing is published here and nothing is sent at first contact; documents are shared after screening, company to company, under confidentiality.
Screening before anything else
This site is run by a filtering company, not a broker. Complete, relevant business inquiries are passed direct to the operating company that holds the material; incomplete or irrelevant ones are not forwarded. We are deliberately selective — a handful of serious B2B inquiries matters more to us than volume.
How we work
- You send a written inquiry with grade, quantity and application.
- We screen it for completeness and relevance; relevant inquiries go direct to the company holding the material.
- You get a written answer on availability, specification and documentation — and a call once the inquiry is qualified.
Documentation & custody proof
Every lot is backed by a complete documentation package held by the operating company: a non-negotiable safekeeping receipt and custody confirmation issued jointly with a bank and an independent inspection body, full lot identification with quantity and storage location, an independent laboratory certificate of analysis for the lot (for copper powder, depending on grade, in the 5N5–6N range), a technical evaluation of the material, and the legal existence documents of the holding company.
These documents are not published and are never sent on first contact. Once your inquiry has passed screening, the relevant documents are shared directly, company to company, under confidentiality.
Business to business only — every inquiry is screened
This site is run by a filtering company, not a broker. The material is held under custody by the operating company we work with, and we forward only complete, relevant business inquiries directly to that company — no brokers, no intermediaries, direct to direct. If an inquiry is not relevant or is missing essential information, it is not forwarded. Too many frauds, too much wasted time: the screening exists so that serious buyers get a serious answer.
Frequently asked questions
- What quantities can I ask about?
- Anything from a qualification quantity of a few hundred grams for laboratory and process trials up to recurring tonnage call-offs — quantity is not a limiting factor. The specification for your lot is confirmed in writing.
- Do I pay import duties or VAT?
- Not while the material remains in bonded storage. Duties and VAT become due only when goods are cleared into free circulation in the destination country, so the customs position depends on your delivery terms.
- Which analysis is used at these grades?
- As a rule in this industry: ICP-OES and oxygen determination below 4N, ICP-MS and LECO combustion analysis from 4N, GDMS scans from 5N. The analysis scope actually supplied with a given lot is confirmed in writing.
- Can you match an existing specification?
- Send your internal specification or a datasheet you are comparing against, and you will get a written answer on whether it can be matched — including a clear no when it cannot.
- Can I call you?
- Inquiries start in writing, with no phone desk at intake, so grades and commitments stay documented. Once your inquiry passes screening, qualified buyers are called directly.
- How is shipping handled?
- Shipment, packaging and customs routing are arranged with the company holding the material, matched to your delivery terms and to the requirements of the grade concerned.
