Special Master Alloys
It is mainly used in the production of nickel-based superalloys and nickel-containing special steels. Niobium can improve the mechanical properties, weldability and creep resistance of superalloys and steels. The large difference in melting points between base metals and niobium makes it difficult to add pure niobium to the molten pool, nickel-niobium alloys added as master alloys are very soluble and have melting temperatures similar to or even lower than normal operating temperatures. This master alloy is also suitable for adding niobium to nickel-copper alloys to improve mechanical properties, for example in cryogenic applications.
Particle size: 5-30mm, 5-50mm, 10-100mm.
Packing: 100kg/250kg iron drum plus pallet, each packaging drum is marked with batch number.
The melting point of NiNb65 master alloy is 1320°C and the density is about 8.5g/cm3
To be stored in a dry place to avoid oxidation.
Other chemical composition requirements, particle sizes and packaging can be provided according to customer requirements.
