Innovations are the core of the company We enjoy a good reputation in the industry, and that's not without good reason. We are regarded as an innovation leader in the field of alloys. A look at the past 130 years shows our extensive contribution to the development of new generations of alloy. Every few years, we have consistently succeeded in devel- oping new alloys. All of this began as innovations in our company. To this day, these generations of alloys remain the basis of our good reputation and quality. Internal measuring techniques to guarantee top quality To ensure the highest quality standards, we have an exhaustive spectrum of different measuring tech- niques in our production and development areas: Chemical composition testing methods We use direct reading spectrum in furnace tests, taking advantage of its reliable analysis structure and fast analysis speed. At the same time, we use fluorescence photometer and inductively coupled plasma spectrometer to confirm the results of the direct reading spectrum, ensuring the consistency of the chemical composition of the pre-furnace sample and the final product. Mechanical property testing methods In addition to the stereomicroscope to measure the surface of the alloy, we also use the metalloscope to measure the microstructure (such as grain size and precipitation) of the alloy. The tensile strength, yield strength, and elongation after fracture are evaluated by electronic universal testing machines. We use Brinell hardness tester, Vickers hardness tester, Rockwell hardness tester, and other equipment to eval- uate the hardness value of our alloy materials. The straightness and radian of alloy materials are tested by high-precision image measuring instruments. The electrical conductivity of the alloy is measured by the bridge method and eddy current method. The residual stress of the alloy is tested by ammonia fumi- gation and the corrosion resistance is tested by salt spray test. 03 About bedra
