What Is Anodizing?<\/h2><\/div>

Anodizing is an electrochemical process that converts the metal surface of aluminum into a durable, corrosion-resistant, and aesthetically pleasing oxide layer. Unlike paint or plating, anodizing becomes an integral part of the metal, offering enhanced wear resistance and a long-lasting finish.
Our anodizing services are widely used in industries such as aerospace, automotive, electronics, and consumer products where surface performance and visual appeal matter most.<\/p>\n<\/div>

Types of Anodizing We Offer<\/h2><\/div>

We provide various anodizing finishes tailored to your application needs:<\/p>\n<\/div><\/div><\/div>

\"type<\/div>

Type I \u2013 Chromic Acid Anodizing<\/h2><\/div>
<\/div>
\n

Type I anodizing uses chromic acid<\/strong> as the electrolyte and produces the thinnest oxide layer (0.5\u20137.6 \u03bcm)<\/strong>. It offers excellent corrosion resistance while causing minimal dimensional change to the part. The coating is grayish in color and has limited dyeing capability.<\/p>\n<\/div><\/div><\/div>

\"type<\/div>

Type II \u2013 Sulfuric Acid Anodizing<\/h2><\/div>
<\/div>
\n

Type II anodizing uses sulfuric acid<\/strong> as the electrolyte and produces coatings 5\u201325 \u03bcm thick<\/strong>. It is the most common and cost-effective anodizing process and allows for color dyeing<\/strong> in a wide range of finishes.<\/p>\n<\/div><\/div><\/div>

\"type<\/div>

Type III \u2013 Hard Anodizing (Hardcoat)<\/h2><\/div>
<\/div>
\n

Type III anodizing is performed under low-temperature and high-current<\/strong> conditions, forming a thick and dense oxide layer (25\u2013150 \u03bcm)<\/strong>. The coating is very hard<\/strong> (up to 400\u2013600 HV) and dark in appearance.<\/p>\n<\/div><\/div><\/div>
