Selective Soldering - nozlle material | 12 January, 2019

I am looking for a good material for selective nozzle. We are currently using Kovar but it is expensive and wears out it has very good wetting properties.I looking for a material or coating that would allow me to keep the binder flow and with less cost / longer nozzle life? Do you have any ideas? What do you use?

We use 4140 steel (same as a lot of other OEM's). The user will need to pre-flux and tin before installing in the machine.
