Nickel Plating

Alexandria Plating Industries, Inc. routinely Nickel Plates materials to the following specifications.

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.

Woods Nickel Strike

Woods Nickel Strike is a good undercoat to many other processes that is corrosion resistant and hard.

Tin-Nickel

Plating Specifications: ISO 2179, ASTM B-605

Tin-Nickel electroplating is typically a 65/35 composition. This electroplating process provides corrosion protection for fabricated articles of iron, steel, zinc based alloys, copper and copper alloys.

Is designed to produce semi-bright, uniform nickel alloy deposits containing a maximum of 0.5 % boron. These deposits have low internal stress and are characterized by resistance to high temperatures, good weldability, brazeability, solderability and high hardness which improves their resistance to wear.
