What material is the cooling plate made of?

"Copper (base and heat-pipes), aluminium (cooling fins), soldered joints & nickel plating"

does it come with pre applied thermal paste

No, it comes with a tube of thermal paste to apply

will this keep my ryzen 5 2600 cool? (im overclocking it to 4ghz 1.3V to 1.4V)

I have been running my rig ITX Gigabyte X570 MOBO with AMD 5600g base 3.9 at 4Ghz and it has not over heated yet. It does run more at higher RPMs, but so far so good.

Will it come with the alternative mounting option for the msi B550i ?

Should come with both mounting hardware , but to be 100% sure make sure you purchase the one that says specifically with socket mounting hardware it comes with.
