Low P EN
Low phosphorus electroless nickel is a technical deposit composed of nickel and phosphorus ( 2-4% ). It provides corrosion protection, higher hardness deposit in comparison with Mid and High P EN and abrasion resistance.
KM EN 824 RoHS COMPLIANCE LOW PHOSPHOROUS ELECTROLESS NICKEL PLATING PROCESS
Physical Properties:
KM EN 824 Make-up: Liquid
KM EN 824 Part I: Liquid
KM EN 824 Part II: Liquid
Description
KM EN 824 is a high-speed, bright electroless nickel deposit with 2 – 4% phosphorous content.
KM EN 824 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.
KM EN 824 exhibits a high and constant deposition rate coupled with exceptional bath stability.
KM EN 824 produces extremely hard deposits with high corrosion resistance and excellent wear and abrasion resistance.
KM EN 824 has a metal efficiency of 8 – 10 times its original make-up with good bath maintenance.
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, 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 micron cartridges should be used
