Titanium finger | 16 July, 1999

My wavesoldering machine is equipped with Titanium finger. What composition of Titanium alloy used ? Any grade difference, and which is the best grade for long life ? An info or website concerning it.

Dear Barden,

Sorry, I am not familiar with what titanium alloy used in the wavesoldering machine. But I have an experience, try not use a flux that contains high percentage of inorganic aicd, especially fluoroboric acid. I have an experience with Brand "A" flux, which contains aboutfew percentage of fluoroboric acid, the flux gradually corrode the titanium finger!!!

All the best wishes, Vic Lau

My wave is over four years old and I have not used up the spare fingers that came with it. The titanium used in the fingers is likely grade 2 . This is one of seven "pure" grades and is characterised by its formability and chemical resistance. For more information than you would ever want about almost any material go to www.matweb.com.
