"KEHMA-SL" is a biodegradable alloy that can decompose much faster than general-purpose magnesium alloys. By quickly decomposing after being used as structural components, it contributes to process simplification. Its unique characteristics also aid in the development of new solutions. Please feel free to contact us when needed. 【Usage Process (Example)】 1. Functions as a structural component 2. Begins decomposition by immersion or spraying with saline solution, etc. 3. All components decompose into powder, simplifying removal *For more details, please download the PDF or feel free to contact us. "KEHMA" is a registered trademark of Kurimoto, Ltd.

"KEHMA-HR" is a lightweight material that creates added value. It uses magnesium, which has a lower specific gravity than aluminum and is the lightest metal among practical metals. It meets the combustion test standards set by the FAA (Federal Aviation Administration). By using this product, it is possible to achieve both lightweight and flame resistance in products that require heat resistance. 【Features】 - It has equivalent heat resistance (creep resistance) in the medium temperature range (around 175°C) compared to traditional aluminum alloys (ADC12 series). - It is a low-cost material that does not use rare earth elements. - It is flame-resistant and suitable for casting and machining (lathe processing). - Compared to general-purpose magnesium alloys (AZ series), it has improved castability (fluidity). *For more details, please download the PDF or feel free to contact us.
