The main provision of professional laboratory test values ??for the application of metallic materials steel, copper materials and aluminum materials in mobile phones, computers, NB chassis, mold, connectors, automotive and other top judges and analysis services. The reason for the exception of applications in material use professional equipment processing, analysis and provide professional advice and solutions. Services: Metal material testing:? Metal microstructures - Surface Observation - Grain size - carbide of - inclusion analysis - case depth - the microstructure of metal coating thickness detecting metal chemical composition to detect the fracture??? observation and analysis of metal mechanical properties (hardness class?) - Material Vickers hardness - Vickers surface hardness - Vickers hardness of the core? - Rockwell hardness of the metal mechanical properties (mechanics) - tensile strength / yield strength / elongation - Bending test - Stretch / Stretch coefficient - thrust / pull / shear / insertion force - torque
