Why Tungsten and Moly are NOT good Additives for PWD Dry Lube
Graphite is the key to a winning dry lube. Plain and simple.
Important Things to Know About Graphite
- Particle Size (mesh–large flake to super fine).
- Hardness (does it easily smear, or is there a gritty feeling left).
- Purity (if its not 100%, what is the filler).
Anything else added to graphite, makes it slower.
Tungsten is harder than graphite, so the addition of tungsten to a graphite blend only adds an abrasive.
Tungsten is harder than your steel axle.
Think about it.
The addition of Moly makes any dry lube compound a single layer lube as you can not stack multiple layers of moly.
Why would you want a single layer lube to begin with?
Both these additives only become a key part of lubrication under HIGH HEAT or HIGH PRESSURE.
If these elements are not present, moly and tungsten become an abrasive.
Both carry a higher a higher rockwell hardness scale rating than pure graphite.
So why do we want them in our lube?
Answer : we don’t want them in our lube since there is literally no stress in a 5 oz gravity fed rolling application.
Plain and simple.
Look at the science.
Do the math.
Pure graphite is the key to a winning lube.
Stacking layers of lube during a proper break in process that can shed away with friction with each race.
How many times will your scout’s car race during a single event?
If you want the fastest first race car, then you know what lube to use.
