Hardness test is an important means to test the mechanical properties of parts. Hardness test can directly test the work piece in the production site, with simple operation and high efficiency, and can quickly measure the hardness value without basically damaging the work piece. Because of the above advantages, hardness test is widely used as the main means to test the mechanical properties of parts in the automobile parts industry. Hardness test of automobile parts ensures the wear resistance, durability and reliability of parts, thus improving the overall performance and safety of automobiles.
In the auto parts industry, Brinell hardness tester is widely used, including aluminum alloy wheel hub, brake drum, brake disc, engine block, cylinder head, connecting rod, crankshaft, piston and other heat-treated blanks and steel products. In the auto parts industry, Rockwell hardness test is also widely used, mainly used to test finished or nearly finished parts, including high-strength bolts, shafts, bearing parts, molds and others.
