Subject: Solder not sticking



I had the oddest experience with solder today. It
wouldn't stick. I am using standard rosin core solder.

I needed some alligator clips, so I went to Radio
Shack and bought some miniature silver-colored
alligator clips and some stranded hook-up wire. The
alligator clips have a hole in which to slip the wire
and strain relief nubbins to hold the wire in place,
but to get a really good electrical connection I think
that I need to solder the wire to the clip through the

No matter what I do, I can't get the solder to stick
to the clip. It will stick to the wire fine (I tried
with the wire ends silvered and unsilvered), but it
just beads up on the clip.

Are there metals that are solder resistant? If so, why
or why did they make alligator clips out of it? Or, am
I soldering wrong?
