Most grades of aluminum cut like soap. Great for tool life but it can be
difficult to get a fine finish. It's gummy and sticks to the tool causing the
cutting edge to foul. A cutting fluid will eliminate almost all of that issue.
Oils will not work on most grades. They just make an already gummy
material even more sticky. There are a lot of commercial aluminum specific
cutting fluids on the market, but they are expensive.
Plain kerosene works just as well if not better.
I can hear the eyebrows going up already! :roll:
Kerosene has a flash point of 100 to 150F the cutting fluids flash points
run 200 to 300F At work I have seen a few small short flares of yellow
flame. At home I have never seen a flare. It can be cut with a 50/50 mix
of oil. That will raise the flash point above 200F but reduce it's efficiency.
As with anything, it is as safe as the operator. It is NOT a flood fluid!
Let it pool up in the chip pan of a machine and your asking for excitement.
Use it as a aluminum cutting fluid should be used and it as safe as oil on
steel. WD40 also works very well as a cutting fluid on aluminum.
It's flash point.... 104F
