Professor Kawamura developed an innovative magnesium alloy that is superior in both strength and heat resistance, called “KUMADAI Heat Resistant Magnesium Alloy.” However, his road to reach the discovery is truly a muddle, combining and mixing an enormous number of elements with Magnesium. Why did he go through a muddle? And what did he learned in the muddle?

Prof. Kawamura is the director of The Magnesium Research Center at Kumamoto University. Magnesium is the lightest among structural metals and is used for computers, mobile phones, and other applications. However, its high flammability makes it difficult to be used in automobiles or airplanes, which are needed to reduce the weight of most things these days. Professor Kawamura overcame this problem by combining and mixing a variety of elements with magnesium. In 2003, his team developed an innovative magnesium alloy that is superior in both strength and heat resistance, called “KUMADAI Heat Resistant Magnesium Alloy.” This was followed by the development of “KUMADAI Non-flammable Magnesium Alloy” in 2012. The use of KUMADAI magnesium alloy in automobiles and airplanes, for example, will enable the reduction of carbon dioxide emissions and improve fuel efficiency due to their reduced weight. For these reasons, KUMADAI magnesium alloy is called an “ecologically friendly material.”
