春日井アルマイト工業 List of Products and Services

"Anodizing" refers to a treatment that creates an oxide film on the surface of aluminum and aluminum alloys. By immersing aluminum in a special solution and performing electrolytic treatment at the anode (+), it is possible to artificially generate an oxide film (aluminum oxide). When immersing products in chemicals, reducing contact points with the fixtures as much as possible or placing contact points in less visible positions helps achieve a clean finish for the final product. 【Specifications】 ■ Compatible materials - A1000 series, A2000 series, A5000 series, A6000 series, A7000 series, A8000 series, die-cast products, castings ■ Maximum work dimensions: W1500×L700×H150 (approximately the size of one tatami mat) *For more details, please refer to the related links or feel free to contact us.

"Oxalic acid anodizing" is a treatment that offers very high wear resistance (more than three times the JIS standard), as well as high corrosion resistance and alkali resistance (chemical resistance), with minimal changes in surface roughness. It is commonly used for aluminum products that prioritize functionality. Additionally, due to the minimal presence of fine cracks, it has high electrical resistance and heat resistance, and good sliding properties, making it suitable for surface treatment in semiconductor-related fields, medical applications, and automotive parts. In the case of aluminum extrusions (1000 series and 5000 series), ultra-hard anodizing with a hardness of Hv450 or more is possible even in thin films. 【Features】 - Excellent weather resistance, does not fade - Enhanced functionality in wear resistance and corrosion resistance *For more details, please refer to the related links or feel free to contact us.
