Standard 40x40 Extruded Aluminum Heat Sink

Versatile, Cost-Effective Thermal Management for Industrial Systems The Standard 40x40 Extruded Aluminum Heat Sink exemplifies the enduring value of classic thermal design. Manufactured from 6063-T5 aluminum alloy via precision extrusion, this profile delivers consistent thermal performance across a wide range of ambient conditions. Its uniform straight-fin geometry maximizes surface area while maintaining low airflow resistance—making it equally effective in natural convection and forced-air cooling setups. Why Choose an Extruded Heat Sink? As an Al Extruded Type component, this heatsink benefits from one of the most mature and scalable manufacturing processes in thermal engineering. The continuous extrusion method ensures excellent dimensional accuracy, high thermal conductivity (~200 W/m·K), and seamless compatibility with secondary operations like CNC machining, drilling, or anodizing. Unlike cast or bonded alternatives, there are no joints or interfaces to degrade thermal path ef…
