Disclosed is a shadow mask comprising an alloy such as an inver type alloy and having {100} texture on a mask face. Also disclosed is a useful process for preparing the shadow mask.

Shadow mask

There are disclosed a corrosion-resistant and wear-resistant magnetic amorphous alloy characterized by having, on the surface thereof, an oxide layer including a crystalline oxide and a method for preparing the same characterized by carrying out the oxidation treatment of the magnetic amorphous alloy at a high temperature and at a high pressure in order to form an oxide layer including a crystalline oxide on the surface of the magnetic amorphous alloy. The magnetic amorphous alloy according to this invention possesses a remarkable corrosion resistance and wear resistance and had an improved magnetic permeability in the mega-Hertz zone.
