Re: Nozzle Wear/Life
I am not familiar with the mechanics of your lead free selective soldering process, but is it possible that a reaction bonded silicon carbide ceramic might be an option here? RBSiC has excellent resistance to thermal shock/corrosion and 360 degree Centigrade will not pose a problem. One problems may be that RBSiC is an extremely hard ceramic that is usually cut to length with a diamond saw. However, RBSiC can be supplied in the form of individual nozzles cut to a predetermined length; as opposed to stainless steel/titanium tube which you would hacksaw to length, I would presume.
You can review the properties of an engineering grade reaction bonded silicon carbide at www.omegaslate.com/producti.htm#rbsc

Nozzle Material
Dear Louis,
Instead of metals you might want to test engineering plastics. Our Celazole PBi has proven its value as welding tip with excelent life time inprovement.
pls check our website for more info on this material. If you are interrested pls do not hesitate to contact me.

Nozzle wear/life
We are using 316 stainless steel tubing for nozzles in our lead-free selective soldering process running at 360 degrees C. The tubing is 10mm OD x 8mm ID. They currently last about 2 months. I have been wanting to run a trial with titanium tubing or some other material with a high probability of lasting longer than our current process. I haven't been able to find any titanium tubing manufacturer who would accomodate such a small quanity 3ft. Any help with a contact or suggestion would be appreciated. ■
