Electroless Nickel Services  
   
     
  With electroless nickel we can plate onto both metallic and non-metallic substrates (using a nickel boron coating) including ceramics and glass. Processes can be tailored to produce stable, corrosion-resistant and chemically resistant surfaces with hardnesses up to 1000Hv. Electroless nickel can produce uniform coating thicknesses in recesses and blind holes and we can design the process to co-deposit PTFE particles throughout the thickness of the coating for long life wear resistance.  
     
  We have also developed coatings to meet the requirements of customers with applications that have to comply with RoHS regulations. We can also finish electroless nickel and nickel boron coatings with immersion gold to give a thin gold layer to aid solderability and reduce contact resistance.  
     
  The electroless nickel coating services we offer include:  
   
 
Medium phosphorous Giving a standard RoHS compliant finish for most applications. A non-RoHS compliant mirror finish is also available
     
High phosphorous A non-magnetic coating giving high corrosion resistance, high chemical resistance and hardnesses up to 1000Hv
     
Nickel boron A very hard coating that can be plated onto ceramics and glass
     
Nickel PTFE An electroless nickel coating co-deposited with PTFE particles to give a long-lasting, low-friction, anti-galling material with through thickness properties. It also has good corrosion resistance, can achieve hardnesses up to 600Hv and has excellent hydrophobic and lipophobic properties
     
Immersion gold Produces a thin layer of gold on top of the nickel coating to give improved electrical properties
     
 
   
     
  Specifications available include AMS-2404, AMS-C-26074, ASTM B-733, ASTM-B-656, MIL-DTL-32119.
