Why you should Choose Anodized Aluminum Heatsink
Improved Thermal Performance
Anodized surfaces can have emissivity values of up to 0.85, compared to 0.05-0.07 for bare aluminum, enhancing heat radiation and leading to improved reliability and longevity of electronic devices.
01
Superior Corrosion Resistance
Anodizing provides a protective oxide layer, which can be up to 25-100 𝜇m thick, offering robust protection against corrosion and extending the lifespan of the heat sink in harsh environments
02
Aesthetic Flexibility
Anodizing can produce a wide range of colors, including natural, black, champagne, blue, red, and more, with consistent and uniform finishes, providing an attractive look
03
Cost-Effectiveness and Value
Compared with several surface treatments such as passivation, electroplating, etc., anodized product benefits in terms of enhanced performance, durability, and reduced maintenance with a cost-effective choice.
04

Somethings that you may concern
01
Is anodizing heat resistant?
An anodized finish is chemically stable, will not decompose; is non-toxic; and is heat-resistant to the melting point of aluminum (1,221 degrees F.)
02
Is anodizing permanent?
Yes, the finish is permanent. On top of that, it is wear-resistant, meaning that it will never scratch or fade and will never need to be touched up.
03
What is the thickness of anodizing?
We always anodize the aluminum heatsink within the limitation of 25-100𝜇m
