ELECTROLESS NICKEL PLATING – min lot $175 (low phos – $250)

Sheffield’s Electroless Nickel Plating Services:

Sheffield’s Electroless nickel plating is widely used for engineering applications due to its properties, including: high wear resistance, high hardness, and corrosion protection. SPI’s Electroless nickel is a conforming coating allowing the deposit thickness to be controlled for a close tolerance finishing on even the most complex geometries. We have many masking techniques for selective plating, so whether it’s blind holes, bearing surfaces, deep bores, or threads, you can count on our electroless nickel to meet your engineering needs.

We currently serve the electronic, semiconductor, medical, and connector sectors as well as many areas of commercial, military, and aerospace manufacturing.
