Well. I sue 3-in-1 oil when soldering aluminium [1], and I've never had
it catch fire. My soldering iron gets to 800 deg_F...
[1] The problem with soldering aluminium is the oxide on the surface of
siad metal. One trick is to put a drop of oil on the metal, then scrape
away the oxidie through the oil, then immediately tin the area with a hot
iron and solder. It sometimes takes a couple of tries, but once it's
tinned you can clean off the oil nd solder the wire, or whatever, in
place. I've used this method to make connections to aluminium plates used
as eelectrodes, etc.

for the 3-in-1 (if what's in the can I used
is the same as the spray;
the spray is all I could find data for, flash point about 101 degrees
F).
Correction. I just learned that the flash point for 3-in-1 oil is 305
degrees Fahrenheit. If I recall correctly, the Laserjet II's fuser is
heated to 320 degrees F., so... still, not good.
