Nickel-aluminum granules, powder
Nickel-aluminum alloys are used as starting materials for production of nickel skeletal catalyst (“Raney nickel”) to hydrogenize compounds.
Nickel-aluminum alloys of the systems Ni-Al, Ni-Al-Ti are prepared by melting down the metallic components, followed by mechanical breakdown of the material until the required coarseness is achieved.
| Alloy grade | Al | Ti | Ni | Fe |
| MP-NiAl50 | 47,0-53,5 | - | remainder | maximum 0,6 |
| MP-NiAl50Ti3 | 47,0-53,5 | 1,0-3,0 | remainder | maximum 0,6 |
| Note: based on an agreement (contract) with the client, alloys can be prepared with other amounts of component content. | ||||
MP – Metal Powder
The size of base fraction, particle distribution in terms of size, and permissible deviations are determined by the individual agreement (contract) with the client.
Delivered fractions, microns: 200-630, 500-800, 6000-15000 and others, based on the client's individual requests.
