Main features:

● This machine is a motor-driven multi-function hardness tester with weight force,which can simultaneously perform Brinell,Rockwell,and Vickers hardness testing functions;

● Optimized mechanical structure and diamond-shaped design,

● Strong structure,good rigidity,reliable,durable,and high testing efficiency;

● The test process is automated,without human error;

● Rockwell hardness is directly read on the dial gauge,while Brinell and Vickers hardness are obtained by looking up the table

● The accuracy meets GB/T230.2,GB/T231.2,GB/T4340.2;ISO6508-2,ISO6506-2,ISO6507-2,and ASTM E18,ASTM E10,ASTM E92 in the United States.

Application scope:

Brinell

● Determination of Brinell hardness of ferrous and non-ferrous materials;

● Determination of Brinell hardness of bearing alloy materials such as lead-based alloys,Babbitt alloys,and tin-bismuth alloys;

● Determination of Brinell hardness of certain non-metallic materials such as rigid plastics and bakelite;

● The Brinell hardness of parts produced by casting,forging,rolling,and other processes is measured.

Rockwell

● Determining the Rockwell hardness of ferrous and non-ferrous materials;

● To measure the Rockwell hardness of high-hardness alloy materials such as cemented carbides;

● Determination of Rockwell hardness of quenching,tempering and other heat treatment materials;

● It is used to measure the Rockwell hardness of some non-metallic materials such as plastics and bakelite.

Vickers

● Determination of Vickers hardness of ferrous metals,non-ferrous metals,surface coatings,laminated metals,etc;

● Determination of Vickers hardness of cemented carbides,glass,ceramics,agate,precious stones,etc;

● Determining the depth and gradient of the hardened layer,nitrided layer,and carburized layer using Vickers hardness test;

● Determination of Vickers hardness of thin plates,sheets,and other small parts.
