Does anyone know the metallurgy content of the flywheel magnets?
Are there any trace elements included, specifically Tungsten?
I have never looked into original magnets as to composition.
However, Ford had a 'magnet steel' in the arsenal that was listed as
.82 -.90 Carbon
2.5 - 2.6 Chrome
.25 - .40 Silicon
Normal trace of Phosphorous
Normal trace of Sulphur
There is no footnote on the material spec as to other allowances.
Someone 'may' have the drawing, and it 'may' say something different.
This would by modern definition be a semi-steel with controlled silicon that is higher than the old fashioned trace allowance of steels.
Look up 'silicon steel'
Maybe there are SS magnets available...
The reason I asked is that I was on a non-automotive form discussing the recharging of magnets.
One participant was sure he was recharging Tungsten magnets.
Tungsten is paramagnetic (just barely attracted to a magnet).
He alleged that Model T magnets had tungsten in them.
Now I have some ammo to fire back with.
Don't mess with Henery
Bob, See if either of these tables from the Henry Ford Trade School metallurgy texts (vintage 1938) have what you are looking for:
Ferrous Alloy Chart
|Ferrous Alloy Chart|
Ferrous Alloy Chart 2018.pdf (202.6 k)
|Non-Ferrous Alloy Chart|
Non-Ferrous Alloys.pdf (46.3 k)
Thank you for the data.
It clearly defined the Magnet recipe.
Maybe anecdotal but article by Murray Fahnestock states the Ford magneto magnets as being tungsten steel......
