i am planning on changing the thermal paste on my laptop, dell inspiron N5110, to coollaboratory liquid pro, and i need to know if the heat sink is made of aluminium as the paste in not compatible with the latter.

You should try cleaning the Heat-sink and fan and replace thermal paste and thermal pads. You should clean remains of old paste and pads very carefully with alcohol and install new. You can use any good quality non electrically conductive thermal paste and you can replace thermal pads with K5-PRO specially designed thermal paste that you can find here
