Black dyeing of iron (iron(III) oxide coating)
We will respond quickly and carefully to our customers' detailed needs, such as 'only one fixture for testing' or 'only a few custom tools.'
Black dyeing treatment is a surface treatment that chemically generates a black oxide film known as magnetite (Fe₃O₄) on the surface of iron, aimed at improving rust resistance and appearance. Features and Benefits of Black Dyeing <Extremely small dimensional changes> The black dyeing film is very thin, so it hardly alters the precision or dimensions of the parts. <Excellent rust prevention due to superior oil retention> The greatest strength of black dyeing is its ability to retain rust-preventive oil due to the structure of the film. This oil retention capability produces excellent rust prevention effects. Most effective applications Due to this characteristic, black dyeing is particularly suitable for products that are frequently handled or require maintenance, such as: - Jigs and tools - Machine parts (cutting tools, gauges, etc.) However, the rust prevention capability of the oxide film itself is limited, and rust can easily occur if rust-preventive oil is not applied. It is not suitable for use in outdoor or high-humidity environments. Our company specializes in small lot requests. We respond quickly and carefully to detailed customer needs, such as "just one jig for testing" or "a few custom tools." For black dyeing processing of jigs and tools, please consult with us.
