3N8 High-Purity Aluminium (>=99.98%) — Manufacturer & Supplier for Germany
3N8 sits between standard industrial purity and 4N. HUABO positions this grade for industrial sourcing cases that require a clear >=99.98% threshold, visible batch data, and a documented compliance trail for European qualification.

Procurement fit
When 3N8 is the right sourcing level
3N8 is useful when remelt-grade material is not sufficient, while 4N is not yet required in every project. This page is intended to make that middle position explicit for German sourcing teams.
Typical sourcing situations
- Projects requiring a higher purity level than 3N2 or 3N5 plus visible batch data.
- Supplier pre-qualification cases where documentation quality matters as much as nominal purity.
- Industrial buyers needing a stable middle step between standard remelt material and 4N.
- RFQs focused on purity, ingot size, technical alignment, and export communication.
FAQ on 3N8
Common questions about 3N8 high-purity aluminium
The answers below are written specifically for sourcing and RFQ scenarios.
What purity level does HUABO typically show for 3N8?
HUABO's 3N8 grade has a minimum purity of >=99.98% with typical batch data showing 99.9847% aluminium. Key impurities are Si at 0.0032% and Fe at 0.0021% — an order of magnitude lower than 3N2. This grade is positioned for applications requiring tight impurity control, such as high-performance alloy production, electronic-grade feedstock, and semiconductor substrate preparation where Si and Fe content directly affects downstream product quality.
How is 3N8 high-purity aluminium produced?
3N8 requires both primary and secondary segregation — the second stage is the core technical barrier at HUABO. Secondary segregation uses directional solidification to push Fe below 0.003% and Si below 0.004%, which is the critical threshold separating industrial-grade from high-purity aluminium. Without this second stage, consistent output above 99.98% is difficult to maintain at industrial scale.
Which ingot formats are available for 3N8?
Standard supply is 8-20 kg small-format ingots produced to YS/T665-2018. This format is designed for precision applications where each ingot enters a controlled production environment. Ingot weight, geometry, and packaging can be aligned to customer specifications including cleanroom-compatible packaging. A Certificate of Analysis (CoA) with full trace element data is provided with each shipment.
Which documents support 3N8 sourcing?
HUABO provides RoHS 2.0 compliance reports (No. TST20241108094C/E, tested by Dongguan True Safety Testing Co., Ltd. per IEC 62321), ISO 9001 (No. 36826Q00159R001), ISO 45001 (No. 3682653261798R0S), and Green-Power Certificate GPA-PMA20230821002 from the China Green Metal Certification Center. For 3N8, HUABO also provides extended trace element analysis beyond the standard 8 elements. SDS and per-batch CoA available on request.
