| Project Background

The materials industry is a fundamental sector of the national economy, while new materials represent the leading edge of materials industry development and constitute an important strategic emerging industry. As one of the three key technologies of the 21st century, new materials serve as the “cradle” for the emergence of new technologies, new products, and new equipment across diverse fields. With the advent of new materials, it is indispensable to conduct analysis and evaluation of their properties, application domains, and value.

As a professional third-party laboratory specializing in materials and component inspection and analysis, MTT leverages years of expertise in testing and analytical work to assist R&D units in formulating quality evaluation programs for new materials and new processes. It also supports buyers in verifying the critical technical parameters of new materials against relevant standards or specifications, and issues authoritative testing and analysis reports.
