Product overview & key benefits
In aluminum alloy plants, K₂TiF₆ is reacted with molten aluminum — usually together with potassium fluoroborate — to make Al–Ti and Al–Ti–B master alloys. The fine TiAl₃ and TiB₂ particles they contain refine the grain of cast and wrought aluminum. K₂TiF₆ is also used to produce titanium metal and titanic acid, and in catalyst preparation.
Buyers usually compare assay, moisture and impurities such as iron, silicon and lead, because these carry straight into the master alloy.
Blends with fluoroborate
White powder that is mixed with potassium fluoroborate before charging into molten aluminum.

Selection & comparison
Choosing for your process
| Your requirement | What usually works |
|---|---|
| Al–Ti–B grain-refiner production | K₂TiF₆ with potassium fluoroborate (KBF₄) |
| Low iron in the master alloy | Agree iron and silicon limits before sampling |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
Pack size is confirmed with the quotation.
Storage
Keep in closed containers in a dry place, away from acids: contact with strong acids can release hydrogen fluoride. Follow the SDS.
From first email to approved supply
Name the product you make
Master alloy, titanium chemical or catalyst: tell us which one and its target composition.
Compare the numbers that matter
Assay, moisture, iron, silicon and lead. Ask for them on the same COA template as your incoming inspection.
Keep it dry
Moisture in the salt adds hydrogen to the melt. Check packaging on arrival and keep opened bags sealed.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
Tell us your requirement. We match the grade.
Tell us what you make with K₂TiF₆, the quantity and the destination port. Add your current specification and we will quote against it.
