heatsink - Does the paint colour matter on a heat sink

Many heatsinks are black because black anodizing is a low cost process that prevents oxidation and corrosion.BTW,it also is an insulator,so if it is important that a transistor be in electrical contact with its heatsink,you can't count on physical contact alone.black anodizing heat sinks,black anodizing heat sinks User rating 4.9/5Price Range $0.10 - $5People also askWhat are the benefits of Anodizing aluminum extrusions?What are the benefits of Anodizing aluminum extrusions?Your extrusions are placed in an electrolytic bath.A low-voltage,high-amperage direct current passes through them.The oxide layer thickens and a porous surface develops.Thickening the oxide layer has its benefits.What are the Benefits of Anodizing Heat Sinks?
