3N2 High-Purity Aluminium (>=99.90%) — Manufacturer & Supplier for Germany
3N2 is the documented entry grade in the HUABO high-purity portfolio. This page is built for German buyers who need a clear >=99.90% threshold, visible batch data, and a clean qualification trail without moving directly to 3N5, 3N8, or 4N.

Procurement fit
When 3N2 is the right sourcing level
3N2 is useful when buyers need documented >=99.90% purity, published batch data, and clean export coordination, while 3N5, 3N8, or 4N are not yet required for the target application. That is the sourcing threshold this page is designed to clarify for Germany.
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
The answers below are written specifically for sourcing and RFQ scenarios.
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?
3N2 is produced on HUABO's multi-stage segregation platform starting with 3N electrolytic primary aluminium from hydropower smelters. Even at the 3N2 level, the material passes through melting in a 25t gas furnace, online filtration, and primary segregation. The segregation purification approach — based on directional solidification — already delivers substantially lower impurity levels than standard remelt aluminium.
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 provides RoHS 2.0 compliance reports (No. TST20241108094C/E, tested by Dongguan True Safety Testing Co., Ltd. per IEC 62321), ISO 9001 quality management (No. 36826Q00159R001), ISO 45001 occupational safety (No. 3682653261798R0S), and the Green-Power Aluminium Product Evaluation Certificate GPA-PMA20230821002 issued by the China Green Metal Certification Center. A Safety Data Sheet (SDS) and per-batch Certificate of Analysis (CoA) are available on request.
