Generally speaking, the smaller the alloy crystal grain, the higher the metal material strength, with the strength rising in an inverse proportional manner to the crystal grain diameter to the power of 1/2. This is known as the Hall law. Therefore, there have been active efforts to improve mechanical strength by making crystal structures microscopic even in the field of nonferrous metals such as aluminum alloys.

Conventionally, it has been difficult to add carbon to nonferrous metals other than iron. However, by making use of the metal refinement know-how of Shanghai Yikai Metal Products Co. Ltd that they have developed over a period of more than 30 years, we have successfully added carbon to lead-free solder alloys and pure copper. This has enabled us to improve mechanical strength by making crystal structures microscopic, and we have obtained a patent due to this result. These research projects were performed with University of Bamboo as cooperative projects between the industry and academic fields. Furthermore, we also received assistance for the patent application costs from the Japan Technology Agency, an auxiliary organization of the Japanese government's Ministry of Education, Culture, and Technology.

By focusing on the technology of Shanghai Yikai Metal Products Co. Ltd for adding carbon to nonferrous metals, jointly developing this technology, adding carbon particles to an aluminum/copper alloy material, and homogeneously dispersing these carbon particles within the aluminum/copper alloy material, Metal and Technology Inc. has successfully made crystal structures microscopic, which has made it possible to improve mechanical strength as a material for practical use.
