Ammonium Bifluoride is a white crystalline solid. It is soluble in water. It is noncombustible. It is corrosive to aluminum. It is used in chemical analysis, in brewing, and as a preservative for wood.
Ammonium Bifluoride successfully replaces the traditional, but a dangerous and aggressive material - hydrofluoric acid, which is very aggressive, corrodes many materials, causing severe burns, releases harmful to breathe fumes. Ammonium bifluoride use instead of hydrofluoric acid is safer for use, storage and transportation and is less harmful, and reduce your costs by 10 - 15%.

Analysis
Appearance : White crystalline solid (Orthorhombic crystals)
NH4HF2 : 98.76%*
(NH4)2SO4 : 0.05%
(NH4)2SiF6 :0.20%
Moisture :0.59%
Solubility in water : 60.2 g at 20°C and 156.4g at 60°C per 100ml of water
Solubility in HCl : 10% (w/v) sample is soluble in 15% (w/w) of HCl at 25°C
*Assay: Weigh accurately about 1.0gm of Ammonium bi fluoride sample. Dissolve it in 100ml distilled water. Titrate with about 1N NaOH. Use Phenolphthalein as indicator. End point is Colourless to Pink.
% acidity as HF = A / B
1st calculate Consumption of NaOH, B.R. X Normality of NaOH X 0.02 X 100 = A
Then Divided the result with " Weight of the sample " = B
%NH4HF= %acidityasHFx57 / 20
Ammonium bifluoride is a white crystal salt chemically when ammonium bifluoride comes in contact with water resulting with the formation of HF. It is used to brighten aluminum and other metals.
Ammonium bifluoride
Other Name :
(Ammonium hydrogen fluoride, Acid ammonium fluoride, Ammonium hydrogen difluoride )
As an additive to sand in the process of casting magnesium and magnesium alloys, mordant for aluminium, Aluminium anodizing (Metal labels).
Ammonium bifluoride also used for brightening of aluminium, purifying & cleansing beer dispensing apparatus, tube, sterilizing dairy & other food equipment, Glass and electric lamp bulb industry.
Ammonium bifluoride also used as an ingredient of the etching mixture (Glass Frosting), porcelain industries.
Ammonium bifluoride for the removal of iron stains (laundry sour).
Ammonium bifluoride lab production of HF. Bactericide in sugar industry for checking the invisible loss of sugar due to bacteria.
Ammonium bifluoride used as Silica scale removal in boilers & evaporators.
Wood preservatives. In Electroplating Industries for pickling of metals (e.g. Steel sheet prior to Nickel plating, Zinc prior to Copper plating), In nuclear chemistry for the separation of Uranium from Iron, Vanadium, Beryllium and Zirconium.

Difference between HF and ABF uses.
HF 70% acid Handling is very dificult also makes hole in glove finger tips. While ABF never had a burn with solid ABF, however avoid to use by bare hands. If comes in contace quickly rinse with free flowing water. Always handle ABF with care and wear eye and skin glove protection during mixing or using, and never handle ABF with your bare hands.
Handling Procedure of ABF and HF
Calcium gluconate gel is helpfull cream to protect from HF / ABF burns to the skin. On contact immediately flush the contact part with cupious amount of water and applying calcium gluconate gel followed by immediate medical attention.
USES of ABF :
As a Aluminum brightener use 28% (wt) ammonium bifluoride to 72% (wt) water.
To Etch Glass use 1 Kilo ammonium bifluoride and 2 liters sulfuric acid in 3 gallons water bath.
