Aluminum fluoride, CAS 7784-18-1, is an inorganic compound with the formula AlF3 and a molar mass of approximately 83.98 g/mol. Its principal industrial use is as a component of the electrolyte in aluminum production, where it helps adjust the bath’s composition and operating properties. For B2B buyers, the right purchase depends on the intended process, required chemical composition, physical form, packaging, and documentation—not just the CAS number. At Azeal Materials, we help buyers clarify these requirements before evaluating a quotation.
This guide is intended for procurement teams, process engineers, distributors, and manufacturers assessing aluminum fluoride for industrial use. It is useful whether you are qualifying a new supplier, checking whether a proposed grade matches an existing process, or preparing an RFQ for a recurring requirement. It is not a substitute for process-specific technical review or the supplier’s safety documentation. Buyers should confirm suitability with their own engineering, quality, and EHS teams.
Aluminum fluoride is an inorganic fluoride salt composed of aluminum and fluorine, represented by the chemical formula AlF3. The formula indicates one aluminum atom for every three fluorine atoms, and the compound’s molar mass is about 83.98 g/mol. Commercial material is commonly supplied as a solid, but appearance and physical properties should be verified against the offered product specification. CAS identity alone does not confirm purity, particle size, moisture level, or suitability for a particular process.
Buyers should distinguish anhydrous aluminum fluoride from hydrated material and other fluoride compounds. The water content and chemical composition of a hydrated form differ from those of anhydrous AlF3, so the two should not be treated as interchangeable without process approval. Specify the required chemical form in the RFQ and ask the supplier to confirm it on the product specification and lot documentation. If your process permits only one form, make that requirement explicit before ordering.
The best-known industrial use of aluminum fluoride is in the electrolyte used for primary aluminum production. In this context, it is used as a bath additive, and its role is tied to the composition and operating conditions of the smelting process. The exact grade and addition practice are determined by the smelter’s process requirements. Buyers should therefore provide the intended application and any relevant plant specification when requesting a quotation.
Aluminum fluoride may also be considered for certain specialty applications, including some glass, ceramic, or chemical processes, depending on formulation and technical requirements. These uses are not automatically interchangeable with smelting-grade requirements. A buyer should confirm that the material’s composition, physical form, and applicable impurity limits are appropriate for the specific formulation. Where an application is sensitive to trace components, request analytical details before approving the product.
A useful specification turns a general product name into measurable acceptance criteria. If you already have an internal standard, share it with prospective suppliers and ask them to identify any deviations. If you do not have one, work with your technical team to define the parameters that affect your process. Do not assume a particular purity or particle-size range is standard across all suppliers or grades.
With competitive price and timely delivery, Azeal Materials sincerely hope to be your supplier and partner.
| Specification item | Why it matters | What to confirm |
|---|---|---|
| Chemical identity and form | Prevents substitution with a hydrate or another fluoride. | CAS number, formula, and whether the product is anhydrous. |
| Assay and impurities | Composition can affect process performance and product quality. | Assay basis, test methods where available, and limits for relevant impurities. |
| Moisture | Water content may matter for handling, storage, and process dosing. | Maximum moisture level and how it is measured. |
| Particle size | Particle characteristics can affect feeding and material handling. | Required range, method of measurement, and whether screening is available. |
| Packaging and storage | Protects the product during transport and warehouse storage. | Pack type, net weight, closure, labeling, and storage guidance. |
Where a numerical target is required, write it into the RFQ with its unit and tolerance. For example, a buyer might request an assay of at least 99.0% by mass, but that figure is an illustrative procurement target—not a claim about every aluminum fluoride product or an Azeal Materials lot. The agreed specification and the lot-specific certificate of analysis should govern acceptance. Confirm whether values are reported on an as-received or dry basis.
Start by stating how the material will be used and whether your process requires anhydrous aluminum fluoride. Identify any existing plant, customer, or regulatory specifications that the supplier must meet. Include critical impurity limits and physical requirements rather than requesting only “aluminum fluoride.” This helps suppliers assess the request against the actual use case.
Ask for a current product specification and a sample certificate of analysis before placing an order. Confirm which parameters are tested for each lot and whether the analytical method and reporting basis are stated. Request the applicable safety data sheet and check that its product identity matches the material being offered. If incoming inspection is required, agree on sampling and acceptance procedures with your quality team.
Price is only one part of the landed-cost decision. Request a quotation that states the quantity basis, packaging, shipment point, delivery terms, validity period, and any applicable charges. Minimum order quantity and lead time can vary with stock, production planning, packaging, and destination, so they should be confirmed for each inquiry rather than assumed. For repeat demand, discuss forecast visibility and how specification changes will be handled.
Review the supplier’s safety data sheet and your site procedures before handling aluminum fluoride. Avoid creating or breathing dust, use the protective measures specified by your EHS team, and follow applicable workplace and local requirements. Keep the product in its specified packaging and follow the supplier’s storage guidance to reduce the risk of contamination or exposure to moisture. Do not rely on general product descriptions in place of the SDS for hazard classification and controls.
At Azeal Materials, we support B2B inquiries by clarifying the requested chemical form, specification, quantity, packaging, and destination before discussing supply options. We can review buyer-provided requirements and help identify which details need confirmation for a comparable quotation. Product availability, commercial terms, and documentation should be confirmed for the specific order. We do not recommend selecting a grade based on CAS number alone when process limits are important.
CAS 7784-18-1 identifies aluminum fluoride, a material used principally as an electrolyte component in aluminum production and also considered for selected specialty applications. To choose the right product, confirm the chemical form, define acceptance limits for assay and relevant physical properties, and review lot documentation and safety information. The most effective next step is to prepare an RFQ that includes your intended application, required specification, quantity, packaging preference, destination, and target delivery schedule. Send those details to Azeal Materials so our team can assess the inquiry and confirm applicable supply options and terms.
