Reviews Hardness Testing Machine

PHR-1 Small Portable Rockwell Hardness Tester (PHR-1)

Portable indentation hardness tester. Single hand operation.
Easy conversion. The test results can be converted to HB, HR,HV and HW easily through conversion table..
High sensitivity. Featured with 100 scales, much more sensitive than Webster hardness testers applied in aluminum alloys industry..
Wide valid testing range equivalent to Brinell hardness 25-150HBW..
Barcol Impressor is mainly applied to test aluminum and aluminum alloys..

Four double-ended picks with eight points: 2 & 3, 4 & 5, 6 & 7, 8 & 9 on Mohs' Hardness Scale.
A glass plate (hardness of about 5.5) which, when scratched, distinguishes hard from soft minerals.
A second hardness plate with a hardness value of 3.5..
A streak plate for testing a mineral streak color.

DLC coating (diamond-like coating)-The tool surface hardness(HV7000) Low coefficient of friction(μ=0.08-0.15)，Strong adhesion resistance.
Use ultrafine grain tungsten-carbide steel matrix，Perfect combination of toughness and hardness，Improve wear resistance while avoiding breakage and fracture.
Manufactured with five-axis precision grinding machine, Each milling bit is tested by tool testing instruments，Good stability of dimensional accuracy.
Unique cutting edge design, specially used in aluminum alloy, copper alloy processing.
Greatly performance for alumimum / aerospace/new energy vehicle. U-groove type design for high feed rating and greatly surface finishing.
