Hi! I am Noel from Toronto. I am about to start a business of computer components. I will be starting with pc cabinets and heat sink. I want to sell copper based heat sinks because they have better thermal conductivity. Bayview Metals will be providing me with the precision metal parts required for manufacurint . They told me that copper is expensive than aluminium. So I have decided to go with aluminium. Is there any way to improve thermal conductivity in an Aluminium Heat Sink?
