How will a bit of rolled flat-bar steel work as a soldering iron tip?
I do a job a few times a year where I need to removed a pile of D connectors from some PCAs. I've made up tips from copper bar which works fine but the tips dissolve very quickly, lucky to get a couple of hours out of it.
I'm not sure thermal conductivity is a big issue as the tip probably has a minute to reheat between connectors.
Will a tip made from a scrap of rolled steel bar do the job?
