Abstract: A spring used in a CRT interconnects a stud pin embedded into a CRT panel and a mask frame mounting a shadow mask thereon so that the spring removably mounts the shadow mask within the CRT panel. In order to minimize or interrupt a vibration energy transmitted to the shadow mask, the spring is formed with a composite metal plate having a laminated structure of more than two materials capable of converting the vibration energy applied thereto into a thermal energy by an internal or interfacial friction. The composite metal plate is preferably composed of a first steel, a zinc alloy, and a second steel. A method of making the spring includes the steps of plating two or more metallic materials in sequence, rolling the plated metallic materials into an integrated composite metal plate, and forming the composite metal plate into a spring shape.

Abstract: A shadow mask includes an aperture portion having a plurality of apertures formed therein, the aperture portion being formed over a predetermined area in a center of the shadow mask; and a non-aperture portion defining a periphery of the shadow mask and formed adjacent to the aperture portion. Only the aperture portion is selectively heat-treated to result in a tensile strength of the aperture portion being 1.2 to 3 times greater than that of the non-aperture portion, and the modulus of elasticity of the aperture portion being 1.5 to 3 times greater than that of the non-aperture portion. The method includes the steps of selectively performing a heat-treating process on only the aperture portion of the shadow mask by mounting a separating cover on the non-aperture portion, the separating cover preventing contact of the non-aperture portion with the gaseous atmosphere present during the heat treating process. The shadow mask is then press-formed.
