Yes it is aluminum. Generally one tab is nickel plated I believe which
is easy to solder to and the other is aluminum. I bought some special
flux and solder which does work, I think the zinc flux here is the
same, used with zinc solder<br>

<p class="MsoNormal">I’m having trouble getting ordinary silver
bearing
solder to flow and bond with the metal tabs at the end of some 5000 mAh
LiPo cells.
What’s interesting is that I can re-solder to any spot where it was
originally soldered by the manufacturer, but I can’t start a new solder
joint. I’ve tried extensive cleaning of the metal, no luck. Does
anyone know what the material is that those tabs are made from? Is it
an
aluminum alloy of some type?<o:p></o:p></p>
