Dielectric strength of anodized is typically measured in how many volts per mil it takes to penetrate the anodize coating and get to the conductive aluminum underneath. With traditional anodizing, most anodizers can only achieve around 500 volts per mil.
Hard coat anodize is Semano’s most popular service – and for good reason. Hard coat has characteristics that are often highly desired including substantially increased hardness, better corrosion resistance, better dielectric strength, thicker coating, better wear resistance and more. Oddly enough, despite these features, hard anodize is actually a much smaller market than clear coat. One reason for this is processing hard coat anodize is much more technically challenging than clear coat.
Clear coat anodize is a very common type of anodize that, as the name suggests, is typically clear. Clear coat anodize is most commonly used for cosmetic or architectural applications where corrosion resistance and “look” is of primary concern. Clear anodize has large pores which is why it typically appears to be transparent as you can essentially see through the anodize. Given its large pore structure, clear anodize is typically the best candidate to accept dye. Dyed clear coat will look much truer to the dye than hard coat anodize for that very reason.
At Semano, we are primarily an anodize company and as a result, offer a wide variety of anodizing services. These anodize services break down starting with what type of metal you will be anodizing. While aluminium is usually the most common metal to be anodized, Titanium can also be anodized at well. Since Semano only offers aluminium anodizing services, we will cover those:
In this video, we cover the different types of Mil8625 anodize and also the different classes and what Semano offers. This video is very basic and we will dive in deeper into the Milspec in future videos.
