The Brinell Test is undoubtedly the best known and the most frequently used test for hardness. It is an easy test to make, is easy to read and the impression can be checked at any time. The presence of an impression is proof that the piece has been tested. The test is especially easy with the King Portable. ALLOYS The increasing use of alloys .
The only change was the alloy which indicates a variance in alloy hardness was the cause of the loss of accuracy. Comprende? Another criticism of the Lee unit is it does not measure below 8 on the Brinell scale. The issue here is that ‘pure’ lead is quoted at 5 Brinell so a hardness tester should measure to this level.Though loads of 500, 1000, 1500, 2000, 2500, and 3000 N are available in a typical Brinell hardness tester, a load of 500 N is used for testing relatively soft metals such as copper and aluminium alloys, while the 3000 N load is often used for testing harder materials such as steels and cast irons.However, the general rule is that the combination of test load and ball diameter .
