Round Aluminum Extruded Heat Sink
The round aluminum extruded heat sink has good corrosion resistance. Due to the use of aluminum profiles, it is resistant to corrosion, because when exposed to oxygen, oxygen causes an oxide film on the surface of the aluminum profile. This film is highly resistant to corrosive objects. The role of corrosion.
