We provide black oxide and metal blackening services for steel components, carbon steel parts, alloy steel parts, machined parts, stamped parts, and hardware components. The black oxide process forms a black conversion layer on the metal surface, giving parts a uniform dark appearance. When combined with oil, wax, or sealing treatment, it can provide additional rust protection. The coating is thin and has minimal impact on part dimensions, making it suitable for precision metal parts and assembled components.

Manufacturing Capabilities:

• Suitable for machined parts, stamped parts, fasteners, tool accessories, and hardware components

• Applicable to carbon steel, alloy steel, tool steel, and selected ferrous metals

• Support for black oxide, hot black oxide, metal blackening, and oil sealing treatment

• Additional processes available, including degreasing, pickling, cleaning, drying, rust-preventive oiling, packaging, and assembly

• Suitable for screws, washers, bushings, gears, fixtures, jigs, connectors, and mechanical parts

Advantages:

• Uniform black appearance for improved product finish

• Thin conversion layer with minimal dimensional change

• Helps reduce glare for tools and mechanical parts

• Improved rust protection when combined with oil or sealing treatment

• Suitable for batch processing of hardware, fasteners, and machined parts

Applications:
Our black oxide finished parts are used in machinery, tool accessories, automotive components, fasteners, fixtures, jigs, instruments, electronics, industrial equipment, hardware parts, transmission components, shaft parts, and precision metal assemblies.
