Silver Plating Beryllium/Teryllium Copper Alloys

Any suggestions on precleaning or striking prior to silver plating.

Te forms an insoluble salt in cyanide. You cannot plate Te-copper in ANY cyanide solution until you FIRST strike in an acid solution, either Nickel or copper sulphate. Once the Te is covered by the strike, then you may go into the silver cyanide and plate away.

We have used a Woods Nickel Strike prior to silver strike, but our Ni strike normally has 50-80 ppm of Copper. Do you think the presence of the Cu would have caused an adhesion problem? I know going in hot will make the Cu not an issue but it doesn't affect any other product I run on this line. Thanks again for the help.

For material Be-Cu you will try use HBF4 5-10% 50 oC activated them before plating.
