Electroless Nickel (EN)
Our family of Electroless Nickel (EN) coatings is extremely diverse and appropriate for a large number of applications. We have both rack and barrel plating capabilities for electroless nickel applications, and are capable of both small and high volume production runs.
Val-Nik Black "NEW"
If you require a bright black finish on your component inquire about our Val-Nik Black process. It is a black nickel coating that is also conductive. This coating has the great physical properties of electroless nickel, but in BLACK!
As deposited, this coating provides a hardness of Rc 56-58 - but it can be heat treated to Rc 64. A mid-phosphorous (5 - 7%) alloy results in a bright uniform coating that is tensile stressed and offers excellent atmospheric corrosion and petroleum resistance.
Another option for a mid-phosphorous (3 - 5%) nickel coating, it deposits at a hardness of Rc 57-60. A semi-bright uniform deposit, it offers superior wear characteristics and corrosion resistance and can be hardened to Rc 68.
This is a duplex coating of high phosphorous and low phosphorous electroless nickel that provides both barrier protection and wear resistance.
This electroless nickel with its high phosphorous (10 - 12%) alloy provides outstanding corrosion resistance. Val-Nik 100 is compressively stressed with a deposit hardness of Rc 48-52 and can be heat treated to Rc 58. Non-magnetic and ductile, it has a melting point of 1630° F.
When wear resistance is key - Val-Nik 106 is the product for the job. This coating has a low phosphorous (2 - 4%) alloy that gives a uniform coating with enhanced adhesion qualities and impact strength. It also provides excellent petroleum and alkaline resistance.
A "composite" coating of electroless nickel and Teflon® that provides a low coefficient of friction. The Teflon® particles are 0.4 microns in nominal size and are dispersed throughout the coating (15 - 25% by volume). This composite is hard, uniform, and is functional at temperatures up to 620° F. Applications needing a dry film lubricant, to be hydrophobic, or that are experiencing "stick-slip" problems are perfect candidates for Val-Nik 121
ALL ABOVE LISTED COATINGS ARE RoHS AND ELV COMPLIANT
All of our electroless nickel coatings can plate over the following substrates:
