What a sobering article. I was always under the impression graphite was a great lubricator. Had no idea it is so corrosive.

Amen Brother, That is why lock shops sell it as it takes out locks. Like I tell my friends, if graphite is such a great lube why do they put it in brake shoes?

molybdenum disulphide is the stuff. Research Sandstrom 28A and read about that. I use it on many things.

Graphite is often used during the manufacture of smokeless powder to aid flow characteristics and keep it from clumping. Certainly was used in the old IMR powders. I wonder if that graphite coated powder could cause a problem in ammunition stored for a few years? Some newer powders such as the Hodgdon's Extreme line are greenish rather than graphite colour. Perhaps a different formulation? Wonder if that matters?

Very common in old powder cans for rust to come out with the powder. Have not seen the green stuff.

One of my university professors, an Electrical Engineer tasked to teach me and others Electrical Engineering for non-Electrical Engineers was once a worker in the space program. Though not directly involved he remembered lengthy discussions about what to use as a lubricant in the extreme cold of space, and graphite was chosen. After the components came back and were disassembled the joints looked like they'd been grinding in sand. Without a gas present in the interstitial spaces between the particles graphite acts as an abrasive and it was literally back to the drawing board for that team.

That is why graphite is used in brake shoes on your car. In the absence of moisture graphite is a abrasive. This is why your brakes don't work well when your brakes get wet. You will also have a change in the same metal if it is a different number but it might take a number of years for it to show up.
