JBC precision/nano tip life for leaded verses lead-free soldering?

[lukego]

Can anyone provide data on the relative tip life for JBC precision/nano soldering iron tips with leaded verses lead-free solder? If you solder lead-free will the tips wear out twice as quickly? How long would you expect nano iron tips to last with leaded solder?

I have started using a JBC NASE for microsoldering and I'm running it at 280C with leaded solder at the moment. I'm also interested in using it with lead-free solder at higher temperatures but I'm concerned about wearing out the tips quickly. I saw a video from a repair shop who said their tips last only weeks and that's given me a bit of a fright.

I'm also using huge gobs of amtech RMA flux and I'm not sure how important that factor is relative to temperature, tips would be welcome!

Well I don't use JBC. Even with my Weller at 350 C of continuous use with lead-free solder, the micro-soldering tip only needs to be changed after 8+ months. Even then the tip was not unusable, I just wanted to change it. Although mileage may vary depending on the job, I believe JBC like all the quality brands will have tips that always deliver good performance. Maybe JBC can help with the data.
