What is a material certification?

Material Certifications, also known as Material test reports (MTRs), state both mechanical and chemical properties of the material, lot or heat number, the specification which the material complies with (AMS, EN, ASME, ASTM, etc.). If your parts are made in the US, you will receive a Material Certification for the US material specified in the quote. If your parts are made in China, you will receive a Material Certification for the China-equivalent of the US material specified in the quote. Figure 1 shows an example of a Material Certification if your parts are made in the US. Figure 2 shows an example of a China-equivalent Material Certification if your parts are made in China.
