In view of this situation, many manufacturers are committed to ensuring the corrosion resistance of titanium and titanium alloy under the premise of increasing the hardness of titanium alloy, and surface carburizing is one of the typical processing technology means. Similar to the surface carburizing treatment of steel, the surface carburizing treatment of titanium alloy is to make the active carbon atoms, diffusion to the internal of titanium alloy, the formation of a certain thickness of higher carbon content of the carburizing layer, after quenching and tempering, so that the surface layer of the workpiece to obtain high carbon content of titanium alloy wire.

Black iron wire application in the process, the main is through the hot metal billet rolling into six point five mm wire rod, and then put it in the drawing into a line of different diameter, the plant and then gradually narrow drawing plate aperture, cooling and annealing, plating process, such as making a variety of different specifications of the wire, the wire compared with ordinary black iron wire, will be more softer, Softness is also very uniform, color is also consistent, widely used in the construction industry, mining, chemical industry, welding mesh, welding coat hanger, reprocessing industry and so on.
