Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

Hardness is an important index of mechanical properties of materials. It refers to the ability of a material to resist another object that does not take any residual deformation. Rockwell hardness test is one of the simplest, fastest and most economical test methods in mechanical performance test. Because it can directly indicate the hardness value, so the test efficiency is the highest. In many cases, other mechanical properties can not be completed. With the rapid development of scientific research and industry in China, Rockwell hardness test method has been widely used in national defense, scientific research, laboratory and factory workshop.

This hardness tester is applied to the laboratory of metal metallurgical factories, mechanical manufacturing plants, industrial laboratories and colleges and universities.
