Latest Patents

Mochida's latest patents focus on a flat-shaped fine Fe-Ni alloy powder. This powder is designed to be used as a magnetic shield coating material for cards and similar applications. The specifications of the powder include a mean particle size ranging from 0.1 to 30 micrometers, a mean thickness not exceeding 2 micrometers, and a coercive force of no more than 400 A/m. The production process involves preparing an Fe-Ni alloy powder with a specific composition that exhibits a saturated magnetostriction constant value within the range of ±15 x 10^-6. The alloy contains 70 to 83% Ni, 2 to 6% Mo, 3 to 6% Cu, 1 to 2% Mn, not more than 0.05% C, with the balance being Fe and incidental impurities. The alloy powder is then pulverized using an attrition mill and subsequently annealed in a non-oxidizing atmosphere.
