Abstract
It is an object of the present invention to provide a fire resistance bond magnet having superior temperature properties and most suitable for convergence use in picture tubes for display and high precision television, and alloy powders for bond magnet, without containing Co which is restricted in resources. The flame retardancy bond magnet having superior temperature properties and most suitable for convergence use in picture tubes for display and high precision television can be provided at low cost without containing Co, by using the alloy powders for bond magnet consisting of Al-Ni-Cu-(Ti, Nb)-Fe without Co, and having an isotropy and mean particle sizes of 10 .mu.m to 200 .mu.m, and kneading, molding and curing the 20 wt % to 80 wt % alloy powders together with a chlorine flame retardant, a flame retardant assistant such as antimony trioxide and zinc boric acid and a binder.
