Standard grades 3N2 to 4N · Germany-based contact
HUABO manufactures high-purity aluminium from 3N2 to 4N; 4N5 up to 99.995% can be requested for project review. Typical compositions for Si, Fe, Cu, Mn, Mg, Zn, and Ga are listed in the product matrix. The standard product basis is individual 8–20 kg ingots. Small quantities, research or pilot demand, plate, wire, precision parts, and feedstock are reviewed against your RFQ. Felix Zhao coordinates the discussion from Germany.
For your next sourcing step
Verifiable sourcing data
Purity grades, typical batch compositions, certificate references, and the direct Germany contact are available before supplier qualification starts.
The product matrix lists typical values for seven trace elements. RoHS and ISO evidence is identified by report or certificate number.
The required batch CoA scope is confirmed against the RFQ before quotation. The agreed specification and delivered batch CoA govern acceptance.
Si, Fe, Cu, Mn, Mg, Zn, and Ga are listed alongside aluminium content. Compare these typical values with your application's limits.
Felix Zhao coordinates specification review, sample requests, quotations, and logistics from Germany.
Process
The production site is in Guangyuan, Sichuan. A multi-stage segregation route brings feed material to the required purity grade. Each batch is chemically analysed before release; the standard product basis is individual 8–20 kg ingots. Project-specific element limits, forms, and test requirements are confirmed through the RFQ.
Core portfolio
The table lists typical production results by weight. The 8–20 kg figure is the individual ingot weight, not the MOQ. 4N5 up to 99.995% is reviewed by project against your trace-element limits.

Forms on requestCustom forms after project review
Individual 8–20 kg ingots are the standard product basis. Other forms are reviewed against purity target, dimensions, tolerances, total quantity, and application.
State the required grade or chemistry limits, form and drawing, dimensions and tolerances, total quantity, application, and packaging needs. Identify small quantities for research or pilot testing explicitly.
Compliance evidence
Key report and certificate numbers are shown directly, with scans available in this section.
Independent testing per IEC 62321 standards. Cadmium, Lead, Mercury, Hexavalent Chromium, PBBs, PBDEs, DBP, BBP, DEHP, DIBP: all below method detection limits. Reports available in Chinese (TST20241108094C) and English (TST20241108094E).
Certificate no. 36826Q00159R001. Covers aluminium smelting and product quality control. Valid to 2029-02-09.
Certificate no. 3682653261798R0S. Occupational health and safety management system. Valid to 2029-02-09.
Green-power product evaluation with Certificate ID GPA-PMA20230821002 and a stated scope of 110,000 t molten aluminium.
HUABO describes two-stage segregation as the process route for 3N8 and 4N. A 4N5 target up to 99.995% is reviewed only against the project RFQ.
Working together
A complete RFQ shortens the review of purity, form, quantity, documents, and delivery window.
Send company or institution, purity target, chemistry limits, form, total quantity, application, destination, and requested date. Response timing depends on the completeness and technical scope of the inquiry.
We review grade, trace-element limits, dimensions, and whether a small quantity, sample, or custom form is feasible for the project.
Required CoA scope plus RoHS, ISO, and other project-specific evidence are aligned before quotation.
After review, feasibility, MOQ, delivery window, documents, and commercial terms are set out in the quotation.
If a sample is agreed, form, quantity, test purpose, and required documents are set before dispatch.
Felix Zhao remains the contact for reorders, batch allocation, and logistics coordination.
