Nickel magnesium master alloys and rare earth nickel magnesium master alloys for nickel hydrogen batteries

1、 Nickel magnesium master alloy for nickel hydrogen batteries: In the negative electrode materials of nickel hydrogen batteries, the high-energy hydrogen storage alloy phase is Mg2Ni. If magnesium is directly added during the production process, it is easy to cause magnesium evaporation, affecting the stability of the components; Adding magnesium as a magnesium master alloy effectively solves this process problem, thereby achieving stable composition and performance of the negative electrode material. 2、 Other nonferrous master alloys for casting: nickel magnesium master alloys, rare earth nickel magnesium master alloys, etc.

DESCRIPTION

 

1. Nickel-magnesium master alloy for nickel-hydrogen battery: In the negative electrode material of nickel-hydrogen battery, the high-energy hydrogen storage alloy phase is Mg2Ni. If magnesium is directly added in the production process, it will easily cause the evaporation of magnesium and affect the stability of the composition; Making magnesium master alloy and then adding it can effectively solve this process problem, so that the negative electrode material can obtain stable composition and performance.

 

2. Other non-ferrous master alloys for casting: nickel-magnesium master alloys, rare earth nickel-magnesium master alloys, etc., mainly used for impurity removal, degassing and refinement modification in casting smelting.
