Re: Brinell vs Rockwell Hardness by fkg on 07/18/05 at 08:32:01 Thanks Robert!I did find some charts on this. I think youre right-I dont think there is a conversion. I think the charts were developed from empirical tests. There is a little variability in the conversion values (depending on which chart I'm looking at) but fortunately this variance doesnt appear to be significant. Vickers is one of the most popular hardness testing techniques. It is a form of microhardness that uses a square pyramid diamond indenter and is suitable for a wide range of materials. Unlike other techniques, it uses the same indenter regardless of the hardness of the material to be tested

It has numerous measurement scales: A to G, 15, 30 & 45 and measures the depth of penetration of a diamond spherocone with tip diameter of 0.2mm and an included angle of 120° or a steel ball ranging in diameter from 1.5mm to 10mm all of which can be applied with a load ranging from 15kg to 3000kg.Whilst tungsten carbide balls may need to be smaller than steel balls (10mm) the accuracy of this test remains maximised by using the largest ball available. Therefore, even for very hard materials it is advisable to use a 10mm tungsten carbide ball where possible along with a suitably high load.

The Rockwell hardness test is a common and versatile hardness test. It measures the depth of indentation in a sample after a certain load is The Vickers test was too time consuming, Brinell indents were too big for his parts and the Scleroscope was difficult to use, especially on his small parts Hugh and Stanley Rockwell together invented this hardness testing method in the USA in the mid 19th century, which involves no calculations and the hardness number is read from a dial or digital display.

Hardness of Electronic Packaging Material Hardness Value Chart Vickers hardness tests are beneficial when one needs to looks at hardness over a large range of values, as it can measure from the lowest to highest recorded hardness. The harder the material, the less penetration depth, thus the corresponding Rockwell hardness value will be lower The greater than expected errors in the calculated results are due to the erratic nature of the documented values (see image) which, if measured accurately should follow a much smoother curve. The curve generated by the formulas (SHN {Q}) is considered (by CalQlata) to be more representative of the actual Shore values than the documented values (SHN).This is a simple system that requires no calculation and no complicated equipment.
