Your partner for high-purity aluminium in Germany
You are not just looking for high-purity aluminium, but a supplier your team can internally champion. As part of the Zhongfu Group, HUABO combines massive upstream supply chain stability with specialized high-precision manufacturing (3N2 to 4N5). We deliver directly to your production with batch-specific CoA, RoHS and ISO evidence, supported by a dedicated contact person in Germany.
Why HUABO
We understand that you are not just evaluating material — you are evaluating a supplier. Here is what working with HUABO means in practice.
Batch data, Certificates of Analysis, RoHS reports, and ISO certificates are documented with reference numbers and validity dates — not just claimed.
Every shipment includes a batch-specific Certificate of Analysis per YS/T665-2018. RoHS reports and ISO certificates remain verifiable at any time.
We show typical batch data with Si, Fe, Cu, Mn, Mg, Zn, and Ga — not just a minimum specification. That makes application fit easier to assess early.
Felix Zhao coordinates technical alignment, samples, quotes, and logistics from Germany. You keep one accountable contact across the relationship.
Core differentiation
The energy positioning is documented through a green-power aluminium product evaluation certificate (Certificate ID: GPA-PMA20230821002, scope: 110,000 t molten aluminium).
Green-power certificate with Certificate ID GPA-PMA20230821002 and 110,000 t scope. Product reference: primary molten aluminium.
Documented evidence package with RoHS report numbers and ISO certificate numbers for supplier pre-qualification and internal approval.
Hydropower-based production supports lower embedded-carbon sourcing compared with coal-powered smelters and aligns with stricter sustainability requirements.
Low-carbon procurement brief
Hydropower direct-offtake & Process
Our plant is located directly in the casting center of the Zhongfu electrolysis facilities ("Factory in Factory"). We take the 99.9% hot green liquid aluminium directly from the electrolysis cells — without remelting and without additional CO2 burden. The subsequent segregation process, secured by 29 patents (including CN121759735A for ultrasonic melt treatment), then achieves the proven 4N5 stability.
Hot, green liquid aluminium (99.9%) is transferred loss-free and directly from the adjacent Zhongfu electrolysis cells.
25t melting furnace for refining and impurity removal. Online filtration system followed by crucible loading.
Horizontal continuous rotation segregation. Produces 3N2 (99.92%) and 4N (99.99%) purity aluminium.
Second segregation stage for deeper impurity separation. Output range: 99.993%-99.995%, including 4N5 when required for high-purity applications.
Cast into 8-20 kg standard ingots. Each batch is chemically analyzed and checked against product specifications before release.
Coded and packaged per customer specification. Export coordination with Germany-based support.
The second segregation stage is the decisive technical barrier for stable high-purity output. It supports routine 3N8/4N supply and 4N5 up to 99.995% when customer requirements call for it.
Planned capacity: 30,000 t/year. Current actual capacity: 5,000 t/year. Projects are scheduled by specification and availability.
Core portfolio
Produced via primary and secondary segregation. Published product grades from 3N2 to 4N, small-format 8-20 kg ingots, and 4N5 up to 99.995% for more demanding applications.

Core product across 3N2-4N (including 3N8/4N). Secondary segregation is the technical key to high purity, and for selected projects the route can be extended toward 4N5.
3N2 / 3N5 / 3N8 / 4N99.92%-99.9936% purity remolten ingots. 8 kg standard blocks. Annual cast capacity 5,000 t. Suitable for downstream alloy production and casting workshops.
5,000 t/year cast capacityBeyond standard ingots, forms such as sheet, wire, electronic guide pins, or smaller feedstock formats can be aligned against your process requirements. Contact our Germany representative for technical alignment.
Forms on requestBeyond ingots
Standard grades remain 3N2 to 4N. For specific projects, extended secondary segregation can support purity targets from 99.993% to 99.995%, alongside customer-specific downstream forms.
The new product images make an important point: HUABO is not only an ingot supplier. When your application needs something beyond standard ingots, we can discuss high-purity sheet, wire coils, electronic guide pins, and smaller feedstock forms on a project basis.
Production facility
58 employees including 16 professional technical staff. ISO 9001 and ISO 45001 certified operations with visible workshop discipline, dedicated process lines, and broader form capability for customer-specific projects.
