The most common Heatsink material is aluminum alloys. Aluminum alloy 1050 & 1070 are with higher thermal conductivity but is mechanically soft. Aluminum alloys 6060 (low stress), 6061 and 6063 are commonly used. Aluminum heat sinks can be extruded, casted, forging and punching.
Copper has excellent heat sink properties in terms of its thermal conductivity; corrosion resistance, biofouling resistance, and antimicrobial resistance. Copper has around twice the thermal conductivity of aluminum.
Copper is three times as dense and more expensive than aluminum. Copper heat sinks are machined and skived. Another method of manufacture is to solder the fins into the heat sink base. Copper is less ductile than Aluminum, so it cannot be extruded into heat sinks.
