Electroless Nickel Plating of Aluminum Alloy 6262

-----

Q. We have been asked to electroless nickel plate Aluminium alloy 6262. In the UK there are no technical references to this material.   Do you know of any processes for cleaning this alloy, We know that it contains Lead and Bismuth, do these represent any contamination problems?    

Any information on this particular alloy would be gratefully received. Thank You

Hi, Mike. I'm confident that the ASM Metals Handbook will have the composition and properties data for this alloy. The metal must be zincated before electroless nickel plating, so the electroless nickel bath should not "see" the composition of the substrate.

I'm a 3rd year physics student and I need know about Electroless Aluminium because I must work with that, I have not any technical references about that,... thanks...

Ed. note: the term "electroless aluminum" is unfamiliar to us, Daniel, please explain the material or the process. Thanks.

+++++ I am a final yr metallurgical engg. student working on electroless nickel plating on aluminium samples what is the remedy for the dots that I get on the sample on plating Vasav Pandya - Jaipur, Rajasthan, India November 8, 2008 Hi. If you can get access to them, Chemical (Electroless) Nickel Plating by G.G. Gawrilov or Electroless Plating: Fundamentals & Applications by Mallory and Hajdu will have all the answers, Vasav. Good luck. Regards, Ted Mooney, P.E.  finishing.com Brick, New Jersey
