2. Description of the Related Art Plated products are widely used in fashionable items such as brooches, buttons, buckles, slide fasteners, cufflinks, and accessories such as necklaces and earrings.
When classified by color, they are roughly classified into gold type and silver or silver white type, and color fashion plating is known, although a small number. However, since silver-white plating is not very satisfactory as a decorative product due to various difficulties and restrictions, gold-colored plating is the predominant proportion of the product.

In the enforcement of the Product Liability Law (PL Law), which is a trend not only in Japan but also in the world, the most problematic defect in the field of sewn products such as clothes and bags is the residual needle during sewing. It is a potential risk of stinging to the human body.
Therefore, we usually check the presence of residual needles with a needle detector on the finished product to prevent danger, but the obstacle to detection of the needle detector at that time is the accessory clothes of such a product. It is the existence of magnetism in plated products such as buttons and broaches.
Therefore, in order to comply with the Product Liability Law, it is indispensable for the plating film for clothing to be non-magnetic so as not to react with the needle detector.

It is also known that metal jewelry such as necklaces or other jewelry that comes into direct contact with the skin of the human body causes a metal allergy, which is harmful or problematic to health and is prohibited under Danish law, for example.

Adhesion to the material and corrosion resistance can be mentioned. Therefore, copper plating with good adhesion is used as the base plating.
In many cases, nickel plating or nickel alloy plating having good corrosion resistance is applied in the middle, and finally gold or silver-white plating is applied on top. Copper-tin alloy plating and copper-tin-zinc alloy plating are already known as non-magnetic silver-white plating, but their adhesion to nickel plating is extremely poor. Therefore, these were applied directly on the copper plating, but, of course, since they have poor corrosion resistance,
This was also impractical.

As the non-magnetic plating, of course, there is silver plating, but it is not suitable for ornamental products because it is easily discolored to brown or black during use. Furthermore, phosphorus-nickel alloy plating having a phosphorus content of 11% or more is known as a non-magnetic silver-colored plating having corrosion resistance, but the essential appearance is darker than general nickel plating. However, it could not be used for silver-white plating. Other examples of silver white plating include nickel-palladium plating and nickel-rhodium plating, but these are out of the problem because they have magnetism.
