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 to allow mutual diffusion of the aluminum layer, forming 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 and scales of over 6μ are generated. 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, and when removing the bolt, it rolls within the clearance between the female and male threads, acting as a lubricant to prevent seizing and galling.
◎ Materials suitable for Aluminaize α treatment
Iron, cast iron, steel, alloy steel, SUS materials, heat-resistant steel, titanium, Inconel, Hastelloy, etc.
