Maximum values for density, friction and bounce?

Physics
#1

What are the maximum values you can use for density, friction and bounce? 

Also what value is used if you use a number beyond the maximum?

#2

I’ve not been able to find the values for density, but it seems that bounce and friction are in the 0…1 range.
