 Nickel
is a lustrous silver white, hard metal which is used in plating jewelry and
beads. Nickel is used for plating since the nickel coat covers the area uniformly,
does not build up on edges, and has very high wear endurance. Nickel has superior
corrosion resistance. Thus nickel is used in plating certain metals beads like
copper, zinc, steel, and iron.Nickel, with its leveling and pore-filling characteristic,
is also an excellent undercoat for the precious metals by reducing the total amount
of the precious metal required to achieve performance specifications. |
