Non RoHS Mid P EN
Non RoHS medium phosphorus electroless nickel is a technical deposit composed of nickel and phosphorus. Non RoHS medium phosphorus electroless nickel produces extremely hard deposits with high corrosion resistance.
NI 33 ELECTROLESS NICKEL PLATING PROCESS
Physical Properties:
NI 33 MAKE UP: Liquid
NI 33 PART I: Liquid
NI 33 PART II: Liquid
Description
NI 33 is a high-speed, bright electroless nickel deposit with 6 ~ 9% phosphorous content, suitable for heavy deposit build-ups and functional applications.
NI 33 process chemically deposits a uniform nickel phosphorous alloys and is capable of plating on a wide variety of substrates. These include aluminium alloys, stainless steel, carbon and alloy steels, copper alloys, etc.
NI 33 exhibits a high and constant deposition rate coupled with exceptional bath stability.
NI 33 produces extremely hard deposits with high corrosion resistance.
NI 33 has a metal efficiency of 8 ~ 10 times its original make-up with good bath maintenance. The optional use of ammonium hydroxide or potassium carbonate to adjust pH made NI-33 a better choice for electroless nickel plating process.
Equipment
Tanks: Titanium or stainless steel which is anodically protected, glass or propylene. (resistant to a temperature of 90°C). Plastic liners (e.g. bags made of polythene) which are loose and thus easy to dispose of. They are suitable for use in stainless steel tanks.
Heating: Heating should be done with PTFE-steam coils or immersion heaters make of SS 304, 316 or glass, porcelain and PTFE.
Agitation: Agitation is highly recommended particularly near to immersion heaters if the latter are in use. Gentle air agitation is recommended but must be avoided directly under any parts being processed.
Filtration: The use of filters made of high temperature resistant polypropylene and free of any metal components is essential. 5 ~ 10 micron cartridges should be used.
