Is it true that the larger the mass is, the coefficients of friction will be greater?

Is it true that the larger the mass is, the coefficients of friction will be greater?

Thanks!

Coefficient of friction is a constant of proportionality. In case of static and kinetic friction it only depends upon the nature of surfaces in contact.

All the laws of friction have been obtained experimentaly. A basic or fundamental theory baced on electromagnetic forces is yet to be developeped.
