A set of round compression plattens available in three different diameters and in steel or aluminium. All plattens are plated for corrosion resistance.

The choice of steel or aluminium will depend on the hardness of the sample and the load required. The aluminium plattens will take up to 20kN but this is not usually available on the 50mm size because of the size of fitting that can be accommodated. The machine fitting will ultimately decide the exact load you can use. Aluminium plattens are for softer samples and point loads MUST be avoided. Steel plattens will take loads up to 100kN but again the machine fitting will determine the exact load. Steel plattens will take more concentrated load than aluminium. If very hard samples are to be tested the steel plattens can be hardened or a tungsten carbide insert added.
