3N2 is positioned for industrial high-purity use cases with a defined purity threshold.
Product detail 3N2
3N2 High-Purity Aluminium (>=99.90%) — Manufacturer & Supplier for Germany
3N2 is the entry grade in the HUABO high-purity portfolio. It gives German buyers a clear >=99.90% threshold, typical batch composition, and a documented qualification trail without requiring a move directly to 3N5, 3N8, or 4N.
>=99.90% purity
Typical 99.9226%
8-20 kg ingots
YS/T665-2018
Typical 3N2 batch value for RFQ alignment and incoming-quality comparison.
Small-format ingots for flexible procurement, internal handling, and downstream production planning.
3N2 runs on the same documented refining and segregation platform as the higher HUABO purity grades.

Procurement fit
When 3N2 is the right sourcing level
Choose 3N2 when the application needs documented >=99.90% purity, typical batch data, and coordinated export handling, while the tighter 3N5, 3N8, or 4N levels are not required.
Typical sourcing situations
- Industrial projects that need a documented entry point into high-purity sourcing with visible batch data.
- Supplier pre-qualification cases where documentation quality matters as much as nominal purity.
- Industrial buyers needing a stable step between generic remelt material and tighter 3N5/3N8/4N targets.
- RFQs focused on purity, ingot size, technical alignment, and export communication.
FAQ on 3N2
Common questions about 3N2 high-purity aluminium
Confirm grade, production route, standard format, and supporting documents before releasing the RFQ.
What purity level does HUABO typically show for 3N2?
HUABO's 3N2 grade has a minimum purity of >=99.90% with typical batch data showing 99.9226% aluminium. Key impurities are Si at 0.0200% and Fe at 0.0261%. This is the entry-level grade in HUABO's high-purity range, sitting above standard commercial aluminium (99.7%) but below the tighter 3N5/3N8/4N grades. 3N2 is produced to YS/T665-2018 with per-batch chemical analysis.
How is 3N2 high-purity aluminium produced?
HUABO describes a 3N2 process route using melting, online filtration, and primary segregation. Suitability is assessed against the agreed chemistry limits and actual batch CoA.
Which ingot formats are available for 3N2?
Standard supply is 8-20 kg small-format ingots produced to YS/T665-2018. This format is designed for flexible downstream use in alloy production, casting operations, and industrial remelting. Ingot weight and packaging can be adjusted to customer specifications. A Certificate of Analysis (CoA) with batch-specific composition data is provided with each shipment.
Which documents support 3N2 sourcing?
HUABO publishes RoHS 2.0 report identifiers TST20241108094C/E, ISO 9001 certificate 36826Q00159R001, ISO 45001 certificate 3682653261798R0S, and Green-Power Aluminium Product Evaluation Certificate GPA-PMA20230821002. Required CoA scope and additional documents are confirmed against the RFQ before quotation.
