Coefficient of Friction teflon on aluminum

Coefficient of Friction teflon on aluminum

Coefficient of Friction teflon on aluminum

(OP)
I have been searching for the coefficient of friction for teflon seal tape on aluminum parts.  I have only been able to find friction coefficients for teflon on steel.  If anyone can help me, thanks alot.

RE: Coefficient of Friction teflon on aluminum

Coefficient of friction with teflon as the fixed specimen (data from "Friction Data Guide, General Magnaplate"):

Flat surface sliding on flat surface
Al alloy 6061-T6

static = 0.24
kinetic = 0.19

RE: Coefficient of Friction teflon on aluminum

(OP)
Thanks! Also, is there a large difference in friction if aluminum is the fixed specimen?  and what if the the aluminum is casting Aluminum Alloy 355-T6 or 356-T6?

RE: Coefficient of Friction teflon on aluminum

I provided the only data that I have.  I do not know the effect of changing the fixed specimen.  Friction is such a tricky subject that it makes generalizing quite difficult.  For a given surface finish, cast Al alloys like 356 should be similar to wrought alloy 6061.
