Phosphor Black?

[7431]

I don't know what the Phosphor Black means.---"the valve finish with Phosphor Black"
Is it a kind of special material for painting?
Thanks!

7431,
maybe you've seen this already, because there are no many interesting results if you search the web for "Phosphor Black"... I found that this finish is used for drilling tools:

What kind of valves are required with that finish? What size?

thanks anegri!

I thinks it's a sort of paint.

7431,
just an idea: is it possible that "Phosphor Black" has something to do with phosphating treatment and phosphate coated surfaces?


In alternative, take a look at:

Hope this helps, 'NGL
