Nickel Sulfamate
Plating Specifications: AMS-QQ-N-290, ASTM B689, QQ-N-290, MIL-P-81728

While nickel sulfamate can be used by itself, it is typically used as an underplate for deposits such as, tin, tin/lead, gold, palladium or silver.  Nickel provides a diffusion barrier that prevents components of the base material from migrating into the subsequent layers of plating. Nickel also provides a hard surface that enhances the wear properties of the metal that are subsequently plated on top of the nickel in separable contact applications.  When used with a top coating of tin, tin/lead or precious metal, sulfamate nickel is an excellent choice for solderability applications. Sulfamate nickel can provide good ductility in applications that require forming after plating.

Nickel Sulfate
Plating Specifications: AMS-QQ-N-290, ASTM B689, QQ-N-290, MIL-P-81728

Nickel sulfate is often referred to as “bright nickel” and is used in applications where decorative reflectivity is required.  Sulfate nickel does not perform well in applications where ductility or solderability is an important consideration.

Electroless Nickel
Plating Specifications: AMS-2404, ASTM B733, MIL-C-26074

Electroless nickel is an alloy of nickel and phosphorus and creates a plated deposit that is harder than electrolytic nickel and offers greater resistance to corrosion. Because the plating process used for Electroless Nickel does not rely on electrical current, the result is it provides deposit thickness uniformity on all surfaces of the plated part including holes and inner diameters.
