| Housing Material | Aluminum |
| Housing Finish | PEO/MAO housing finish: Plasma electrolytic oxidation (PEO), also known as microarc oxidation (MAO), is an electrochemical surface treatment process for generating oxide coatings on metals. It is similar to anodizing, but it employs higher potentials, so that discharges[1] occur and the resulting plasma modifies the structure of the oxide layer. This process can be used to grow thick (tens or hundreds of micrometers), largely crystalline, oxide coatings on metals such as aluminium, magnesium and titanium. Because they can present high hardness[2] and a continuous barrier, these coatings can offer protection against wear, corrosion or heat as well as electrical insulation. |
