Frequently Asked Questions

Why is particle size critical for master-alloy production?

Too-fine particles flotation-loss into the dross; too-coarse particles take too long to dissolve in the molten aluminium. Typical D50 target is 15-50 microns depending on casthouse setup.

How does it differ from K2ZrF6?

Different refining metal: K2TiF6 is for titanium-based grain refiners (Al-Ti-B), K2ZrF6 is for zirconium-based grain refiners.

Is it the same as "potassium fluotitanate"?

Yes — "potassium fluotitanate" and "potassium hexafluorotitanate" are different names for the same compound (K2TiF6).

Can custom particle size be supplied?

Yes — D50 ranges from 10 to 100 microns are available with 4-6 weeks lead time.
