Aluminum Fluoride (CAS:7784-18-1): Uses, Specifications, and Buying Guide

Aluminum fluoride, commonly written as AlF₃, is an inorganic fluoride used primarily in aluminum production, where it helps adjust the properties of the electrolyte used in the smelting process. For B2B buyers, the right grade depends on the intended process and on measurable requirements such as chemical composition, moisture, particle size, and packaging. I recommend comparing current technical data sheets (TDSs) and safety data sheets (SDSs) rather than relying on the product name alone. At Azeal Materials, we help buyers clarify these requirements before requesting a quotation.

Key Takeaways

• Aluminum fluoride’s principal industrial application is as a process additive in aluminum smelting.
• Confirm the grade against your process, especially for purity, trace impurities, moisture, and particle-size requirements.
• Price, minimum order quantity, packaging, and lead time depend on the requested specification, order volume, and shipping destination.
• Request a current TDS, SDS, and available batch documentation before approving a supplier or placing an order.

Who This Guide Is For

This guide is for procurement teams, process engineers, distributors, and manufacturers evaluating aluminum fluoride for industrial use. It is intended to support early-stage product and supplier assessment, not to replace process-specific technical advice or a site safety review. Buyers should confirm all acceptance limits with their production and quality teams before placing an order. Where a particular application requires a regulated or customer-approved grade, those requirements should be stated in the inquiry.

What Aluminum Fluoride Is

Aluminum fluoride is an inorganic compound made up of aluminum and fluorine, with the chemical formula AlF₃ and CAS Registry Number 7784-18-1. Reference properties for anhydrous aluminum fluoride include a molar mass of approximately 83.98 g/mol, a density of about 3.10 g/cm³, and a melting point reported near 1,291°C. These values describe reference material and should not be treated as a substitute for a specific product’s TDS or a measurement certificate.

Commercial material is supplied to defined product specifications, which can differ between suppliers and applications. Buyers may encounter descriptions based on purity, physical form, particle-size distribution, or process suitability. Hydrated materials and other aluminum fluoride forms should not be assumed to be interchangeable with anhydrous product. Verify the product identity and form against the documentation supplied for the grade under consideration.

Types, Specifications, and Application Matching

Common specification areas

For aluminum smelting, buyers commonly assess chemical composition alongside physical characteristics that affect storage, handling, and feeding. A specification may include assay, moisture or loss on drying, and limits for impurities such as silica, iron, sodium, or phosphorus compounds. The relevant impurity list and permitted limits depend on the buyer’s process and internal quality controls. Do not assume that a grade described as “high purity” meets your own acceptance criteria unless the numerical limits are documented.

Physical requirements can include particle size, bulk handling properties, and packaging format. These details can influence material flow and compatibility with existing equipment, but actual suitability should be confirmed with the end user or process team. Ask whether values are guaranteed limits, typical values, or results from a particular batch. This distinction helps prevent a typical specification from being treated as a contractual acceptance limit.

Match the product to the application

In aluminum production, aluminum fluoride is used as a bath additive in the electrolytic smelting process. Buyers should specify the process and the parameters their plant uses when discussing a suitable grade; the supplier should not infer a full process recipe from a product inquiry. For other proposed uses, first confirm that aluminum fluoride is appropriate for the application and that the required grade is available. If the intended use has special purity, regulatory, or customer-approval requirements, include them at the quotation stage.

A Practical Selection Framework

1. Define the use: State the process, end-use requirements, and whether the material is for routine production, evaluation, or distribution.
2. Set acceptance limits: Identify required assay, impurity limits, moisture, particle size, and any physical handling criteria.
3. Review documentation: Request the current TDS and SDS, plus a certificate of analysis (CoA) or other batch documentation where available and required.
4. Confirm the supply format: Specify packaging, labeling, palletization, shipping destination, and any storage or handling constraints.
5. Compare commercial terms: Evaluate the quotation alongside specification fit, documentation, delivery schedule, and communication quality.

Before final approval, have the production and quality teams review the proposed specification. If a change in supplier or grade could affect process performance, discuss whether a sample or controlled trial is appropriate for your operation. Agree in writing on the specification and documentation that will apply to the order. This creates a clearer basis for purchase approval and incoming inspection.

Pricing, MOQ, and Lead Time

Aluminum fluoride pricing is not determined by chemical identity alone. It can vary with specification, order quantity, packaging, production availability, freight, and destination-specific handling requirements. Minimum order quantity (MOQ) and lead time are likewise supplier- and order-dependent, so buyers should request current terms rather than rely on general market estimates. When comparing offers, check that the quotations cover the same grade, packaging, shipping terms, and documentation.

For a more useful quotation, provide your target quantity, delivery location, required date, preferred packaging, and specification limits. Also state whether you need a one-time shipment or a recurring supply arrangement. If your specification allows alternatives, identify which parameters are flexible and which are mandatory. Clear details reduce the risk of receiving a price for a product that does not meet your process needs.

Supplier Evaluation Checklist

A supplier assessment should cover technical fit as well as commercial terms. Confirm that the supplier can identify the product by CAS number and provide documentation for the offered grade. Ask how product specifications are communicated, whether batch-specific records are available, and how packaging and shipment details are confirmed. For an export order, clarify the shipping route, required documents, and responsibilities under the agreed delivery terms.

• Does the TDS define the material form and relevant chemical and physical parameters?
• Are guaranteed limits clearly separated from typical values?
• Can the supplier provide an SDS and the batch documentation required by your quality system?
• Are packaging, labels, quantity, and delivery terms stated in the quotation?
• Is there a clear contact for technical questions and order coordination?

Safety and handling documentation should be reviewed before purchase and before the material is introduced to a facility. Fluoride compounds require appropriate controls, and the correct precautions depend on the specific product and workplace conditions. Use the current SDS for hazard information, storage guidance, personal protective equipment, and emergency measures. Ensure that receiving, storage, and handling procedures are approved by your site’s safety personnel.
