Hard alloy bending strength testing machine | three-point bending testing machine is used to test and analyze the mechanical properties of hard alloy materials such as compression and bending. It can automatically obtain test parameters such as force, fracture strength, bending strength, compression strength, elastic modulus (Young's modulus), etc. It can also conduct tests and provide data according to international standards and industry standards such as GB, ISO, JIS, ASTM, DIN, etc. After selecting different accessories according to the product, it can conduct tensile, compression, bending, shear, low cycle fatigue and other tests. The measurement and control software has three closed-loop control methods of stress, strain, and displacement. It is connected to a computer printer to achieve full computer control and print standard test reports; Using the Windows operating system to dynamically display experimental data curves, experimental data can be freely deleted and added, making curve operations more convenient relaxed. Curve traversal can be done anytime, anywhere Overlay Separate Scaling Printing and other electronic display monitoring

The bending strength testing machine for hard alloys meets the testing standards of GB/T 3851-1983 "Determination of transverse fracture strength of hard alloys" and GB/T5166-1998 "Determination of elastic modulus of sintered metal materials and hard alloys".According to the national standard GB/T3851-1983, the principle is to place the specimen freely flat on two points of the fixture support of the testing machine, and apply a static force at the midpoint of the span to fracture the specimen.
