Anodizing 1. Anodizing is an electrochemical process that improves a metal's corrosion and wear resistance, as well as its aesthetics. 2. Type II anodizing's electrolyte is sulfuric acid, producing parts with a thin anodizing thickness of 8-12μm, ensuring good corrosion resistance. 3. Type III anodizing, or hard anodizing, produces a thicker oxide layer (35 to 50μm), offering higher wear and corrosion resistance. Furthermore, Type III anodic films are hard (70 Rockwell C). |

As-machined Machined surfaces are achieved through the cutting action of a mechanical CNC machining process. During the machining process, the tool removes excess material from the workpiece to form the desired cutting grain surface. The process of forming machined surfaces involves machining methods such as turning, milling, grinding, and drilling. |

Sand blasting Sand blasting utilizes the impact of high-speed sand flow to impact sand or other granular materials onto the surface of the object being treated, in order to achieve the purpose of cleaning, removing dirt and improving surface quality. |

Powder Coating Provides a continuous, protective color finish on parts using evenly applied, heat-cured paint. Thickness is usually .006"-.012" and conforms to ASTM D7803 and various MIL and FDE specifications. Various colors and sheens can be chosen. |

Mirror Polishing Mirror polishing is a precision processing technology that combines mechanical polishing and chemical treatment to achieve extremely high smoothness and reflectivity on the material surface. It can eliminate tiny scratches and form a smooth surface that is as smooth as a mirror and without defects. |

Black Oxide Black oxide is a type of conversion coating for ferrous materials, such as steel and stainless steel, which blackens the top layer of the material. It can be used to reduce reflection and glare, as well as provide some additional corrosion resistance without affecting part dimensions. |

Spray Paint Spray paint achieves fast and even coverage through high pressure or gas atomization of paint. It is suitable for complex surfaces and detail processing and is characterized by high efficiency and flexibility. |
|
|
Brushing Brushing can produce a unidirectional satin effect through mechanical polishing, which can not only improve the texture and beauty, but also eliminate minor flaws and enhance wear resistance. |
|
|
Alodine Alodine is a surface finish process primarily for aluminum and its alloys, increasing their corrosion resistance, paint adhesion, and electrical conductivity. |
|
|
Electroplating Electroplating is a process that uses an electric current to deposit a thin layer of metal onto a substrate surface to enhance corrosion resistance, aesthetics or functionality, but the process can also be applied to non-conductive substrates such as plastics and ceramics. |

Passivation A colorless coating that improves corrosion resistance for 200 and 300 series and precipitation hardened corrosion-resistant steels by removing free iron from the surface. |
