Tungsten Carbide Graded Powder

Due to increased pressure from the EPA, and a desire for the finest possible grades of Tungsten Carbide, many companies turn to ATI Alldyne to pre blend ready to press tungsten carbide mixed with a variety of additives to attain specific attributes and qualities. For your convenience, we provide a sampling of our hundreds of catalogue grades, so you can get a sense of the range and variety of functions our grade powders can serve.

Tungsten Carbide Graded Powder:  (Cemented Carbide), 60 mesh to 325 mesh all grades containing Cobalt (Co), Nickel (Ni), Titanium Carbide (TiC) TaC, NbC, Cr3C2, VC and others  

Reproducibility in Hundreds of Varieties

ATI Alldyne is uniquely positioned to partner with you in the development and production of custom graded or ready-to-press powders.  We have a catalogue of over 800 individual grades, with over 50 separate grades being produced each month. Our Gurley facility produces large varieties of graded powder under strict manufacturing guidelines so as to eliminate cross-contamination, and improve reproducibility.

Standard and Customer Specific Formulations Available
Granule Size:   -60 +270 Mesh
Typical Binders:  2% Paraffin Binders

All powder is commercially uniform in purity.  The Chemical and Physical Analyses are determined for each production lot of powder by using commercially accepted methods.  The results of all relevant tests are reported to the customer on a Certificate of Analysis.

50 kg/100 lb packed in a polyethylene bag within a 3½-gallon plastic pail, or 250 kg/500 lb packed in a polyethylene bag within a 17-gallon drum, or as requested by the customer.
