Aluminized α treatment suitable for preventing galling and seizure of hex bolts and nuts.
It is highly resistant to corrosion, seawater, and heat, and does not suffer from corrosion degradation or deformation even at high temperatures!
◎What is Aluminaize α treatment… It is a processing method that involves performing low-temperature thermal diffusion treatment on the aluminum layer on the surface, allowing the aluminum layer to interdiffuse with the base material to form an alloy layer (Fe-Al intermetallic compound). ◎Why does it not seize… When the surface of the screw or the mating material reaches high temperatures, oxidation occurs, resulting in the formation of scale over 6μ. When removing the bolt, the generated scale accumulates (sticks) in the clearance between the female and male threads, causing seizing or galling. The scale from the Aluminaize α treatment is a maximum of 2μ, allowing it to roll within the clearance between the female and male threads when removing the bolt, acting as a lubricant and preventing seizing and galling. ◎Materials suitable for Aluminaize α treatment Iron, cast iron, steel, alloy steel, SUS materials, heat-resistant steel, titanium, Inconel, Hastelloy, etc. *For more details, please contact us or download the PDF.
