Standard Test Method for Indentation Hardness of Aluminum Alloys by Means of a Webster Hardness Gage Significance and Use 4.1 The Webster hardness gage is portable and therefore useful for in situ determination of the hardness of fabricated parts and individual test specimens for production control purposes. to prevent prohibited uses, and promptly notify ASTM of any infringements of copyright or terminated. Write it before hardness symbol, that is 15HW. The disadvantage is that the machines that take the reading are large floor-standing units (not benchtop), and theyre more expensive than Brinell or Rockwell machines. Its also helpful in combining different materials. For this purpose, many Standards of international level such as ASTM E140, ISO 18265 have converted scales.

Every one of our tester models operates in the same manner. %%EOF The smaller the indentation depth is, the higher the hardness value is, while the bigger the indentation depth is, the smaller the hardness value is. Therefore, there are a number of tables which should be consulted while doing the process. Indentation hardness measures the resistance of a sample to deformation due to a constant compression load from a sharp object. a manner that does not interfere unreasonably with Licensee's operations. Licensee and/or ASTM have the right to terminate this Agreement Aluminum alloys have high ductility and corrosion resistance.

Termination:This Agreement is effective until For softer materials, there are alternate scales using a 1500 kg or 500 kg load to avoid excessive indentation. The average of two measurements taken at right angles is used for the diameter to ensure accuracy. Its vital in those cases to have a Webster handheld hardness tester close by and ready to go. Knowing about the hardness tests only is not sufficient, how to accurately process it? Vickers hardness of Aluminium is approximately 167 MPa. Select your model $1,996.00 excl. The advantages of the Vickers hardness test are that extremely accurate readings can be taken, and just one type of indenter is used for all types of metals and surface treatments.
