Nickel Powders available from Hart MaterialsCarbonyl nickel powdersThe purest grades of nickel powder that are readily available in commercial quantities are manufact to react with carbon monoxide to form nickel tetra carbonyl. The extremely pure gaseous Ni(CO)4 is
Spherical Vale Carbonyl Nickel - Type 123The specified nickel content of Vale Type 123 carbonyl nickel powder – 99.98 %nickel – represent the highest level of purity available in regular commercial pro-duction. It is manufactured in very large quantities and is not merely a specialgrade with limited production.
Vale Nickel Powder Type 123 has been the backbone of nickel powder technologyfor decades. The product consists of discrete, approximately spherical, particleswith a tightly controlled and consistently reproducible particle sizedistribution. It is used extensively in the production of powdermetallurgical parts and in synthesis of synthetic diamonds. It is alsothe primary binder, together with carbonyl iron powder, used in themanufacture of Tungsten Heavy Alloy components used primarilyfor medical, defence and aerospace applications.
Type 123 special Hart Materials’ gradesHart Materials also offers a number of different size fractions ofcarbonyl nickel powders, all based on Vale Type 123, but availablein four different size ranges.
Filamentary Carbonyl Nickel Powders - Vale Nickel Type 255Vale Type 255 carbonyl nickel powder consists of filamentary particles a completely differe reproducible particle distribution and the same high level of chemical purity as Vale 123.
The advantage of the filamentary structure is that it can be used to create an electrically c the construction of nickel-containing batteries where the nickel matrix acts as the carrier
Type 255 is also the primary binder in nickel based tungsten carbide components used in stee
In addition Vale Type 255 nickel powder is also used in the manufacture of electrically cond

NOVAMET Type 525 Regular and Type 525 Low DensityNovamet Specialty Products Corporation manufactures two highly refined gradesof filamentary carbonyl nickel powder. These are designated Type 525 Regularand Type 525 Low Density. Since they are derived from material refined by thenickel carbonyl process they exhibit the same high purity as Vale Type 123 andVale Type 255.
These two grades of filamentary carbonyl nickel powder are employed in similarapplications to Vale 255, such as nickel battery manufacture and the productionof electrically conductive coatings used in RFI/EMI shielding application.

NOVAMET Special Spherical Nickel Powders - Type 4SP and SNPNovamet Specialty Products Corporation manufactures five different grades of highpurity smooth spherical nickel powders produced, not by the carbonyl process, but bygas atomisation.
Novamet Type 4SP – 10 μm powder at 5,000 times magnification demonstratesthe precise spherical nature of the 4SP/SNP particles and the smoothness of theirsurfaces. This morphology accounts for the very high values of Tapped Density of theseproducts.
The typical chemical compositionof all of this range of powders is:
Ni 99.6%
O2 3,000 ppm
Fe 800 ppm
C 30 ppm
S 30 ppm
There are four separate grades available of this type of nickel powder with typical physical properties as shown below.
