Short answer: Heat sinks and thermal management parts use aluminium 6063 for light economical cooling, copper where high conductivity is needed, aluminium-copper hybrids for compact high-power modules, anodised stainless for corrosive duty, and folded aluminium fins to maximise surface area, all chosen for thermal conductivity, weight and corrosion resistance.
At a Glance
What Thermal Duty Needs
Conductivity and weight lead the choice, with the basis in our Metal Strength Comparison and expansion notes in our Thermal Expansion Guide; conductivity context is in our Electronics Guide.
Material Choice
Aluminium 6063 suits most sinks and copper serves high-power modules, with the aluminium basis in our Aluminium Supplier and copper basis in our Copper Supplier; data-center context is in our Data Center Guide.
Fin and Form
Fins are extruded, folded or bonded to add area, with finishing in our Anodizing vs Powder Coating Guide and surface care in our Surface Treatment Guide; corrosion care is in our Corrosion Protection Guide.
Quality and Sourcing
Sink stock is checked by inspection, with methods in our Quality Inspection Guide; buyers confirm grade via our Mill Test Certificate Guide and pack per our Export Packing Guide.
