is cost-effective and durable 3 layer (nickel, copper, nickel coating). Good for indoor use and can be acceptable for outdoor environments if suitably protected from the elements. The hardness of the Ni offers good abrasion resistance.
is a popular coating in the medical industry. It is a conformal coating with good resistance to high temperatures, corrosion and high humidity conditions.
Simple protection and allows good adhesion for magnets that are part of an assembly. Low cost but not suitable for long term without additional environmental protection.
is one of the best performers for corrosion resistance and is an over-mold process. It is typically the thickest coating available and has multiple colors available.
has similar properties to gold and is typically selected under unique situations.
