Zincflux Flux for Zinc Metal Treatment
The melt-treatment flux for zinc and zinc alloys — used to help separate clean metal from oxide dross. A sister grade to our cover flux and granulated flux.
Chelora Chemicals delivers Zincflux to zinc melters, die casters and galvanizing plants across the United States, with a batch COA and SDS on every consignment.

What Zincflux is used for
Zincflux is a flux for treating zinc metal in the melt. Zinc melts at only around 420 °C, and molten zinc builds oxide dross on the surface. A flux helps that dross release trapped metal, so more of the charge is recovered as usable zinc.
Industry references describe commercial zinc fluxes as proprietary products, generally based on zinc chloride, ammonium chloride or a mixture of the two. The exact composition varies by grade, so we confirm it on the batch SDS rather than quote one formula here.
Typical use points
- Zinc ingot and scrap melting. Treating the melt to separate dross from metal.
- Zinc alloy remelting. Recovering metal from skimmings and die-cast scrap.
- Die-casting furnaces. Keeping the melt clean before casting.
- Galvanizing kettles. Where a flux is specified for the zinc bath.
Not for aluminium melts
Fluxes are matched to the metal. For aluminium use cover flux, alkali remover or magnesium remover.

Importing into the United States
Flux blends are chemical mixtures, so each component needs a TSCA Inventory check. Under TSCA section 13 the importer of record, or its authorised agent, certifies each shipment to US Customs and Border Protection. We agree in writing who files that certification before the first consignment moves.
Which party carries that duty follows the Incoterm. On FOB, CFR or CIF terms it is usually the US buyer; on DDP terms it can be the seller or its agent. Safety data sheets and labels are supplied to OSHA's updated Hazard Communication Standard.
| Item | How it works |
|---|---|
| Delivery points | Any nominated US plant, warehouse or port of discharge |
| Incoterms quoted | FOB · CFR · CIF · DDP |
| Importer of record | Agreed in writing before the first shipment |
| TSCA certification | Section 13 certification filed at entry |
| Documentation | Batch COA, SDS, packing list, certificate of origin |
Note: regions describe where we deliver, not where we hold inventory. Lead time depends on producer scheduling and transit, confirmed in the quotation.
How we supply Zincflux
Chelora Chemicals is a supplier and sourcing partner, not a manufacturer. Flux performance depends on matching the grade to your furnace and charge, which shapes how we select producers on this line.
We place your order with whichever qualified producer best matches your grade, price point and delivery window, and confirm US import requirements before booking.
- Composition confirmed before we quote. Components and CAS numbers come from the SDS, not assumptions.
- TSCA status settled first. We agree who files the section 13 certification before shipment.
- Batch traceability to the producing plant. Chain-of-custody records on request.
- One desk for the melt shop. Order alongside degassing tablets and ceramic foam filters.
Pack format matched to your plant
Tell us your preferred format and handling route and we will quote and classify to it.
Format confirmed at quotation
Pack type and size are agreed against your handling method and the grade supplied.
Incoterms to suit you
Quoted on the Incoterm your purchasing team works to, with documentation filed before booking.
Trial / sample quantities
Small quantities for furnace trials before a commercial order is placed.
Chloride-based fluxes can fume — ventilate the melt shop
Hazard classification depends on the grade. The safety data sheet supplied with your batch is the authoritative document.
Hazard information
GHS signal word, H-statements and transport class are listed on the SDS for the specific grade and are not repeated here, so nothing on this page can contradict your batch document.
Storage
Keep in closed containers in a cool, dry, well-ventilated area, away from moisture and incompatible materials listed on the SDS.
Handling
Use local exhaust ventilation when adding flux to a hot melt, wear eye and skin protection, and follow your site's hot-metal procedures.
Transport
We confirm and document the exact classification and routing for your shipment and destination before booking.
Every batch, documented
We verify documentation before dispatch so there are no surprises at your incoming-goods bench.
Specification agreed
Grade, form and composition basis confirmed against your furnace and charge before order placement.
Producer batch testing
The producing plant tests each batch against the agreed specification before release.
Documentation review
COA, SDS and TSCA data checked by our desk before the shipment is booked.
Traceable dispatch
Each shipment is traceable to its producing batch, with chain-of-custody records on request.
How zinc flux works in the melt
Molten zinc forms oxide dross at the surface. Zinc handbooks note that zinc alloy can be recovered from oxide skimmings by treating the charge with a flux, and that proprietary zinc fluxes are based on zinc chloride or zinc ammonium chloride.
A flux acts as a cleaning and purifying agent, helping dross release the metal trapped in it. Pair it with degassing tablets and ceramic foam filters where melt cleanliness matters.
We do not publish operating dosages here; this is background only. Full technical documentation accompanies every shipment, and process detail is best confirmed with our technical desk.
