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. The smallest size of specimen is about 25mm25mm. Aluminium Alloys Explained Alloy 6005/6005A has properties between those of alloys 6061 and 6082 and can sometimes be used interchangeably with these alloys but 6005/6005A has better extrusion characteristics. 3 of this License, without ASTM's prior express written permission.

The Webster hardness testing for aluminum alloy material is applied the most in aluminum alloy section factories and aluminum alloy doors, windows and walls in the constructional. Our portable hardness testers are made in three distinct models for testing brass, aluminum, copper, and mild steel. Model A does not provide numerical values of hardness and Model B-75 covers only a part of the range of interest for aluminum alloys. other than taxes on ASTM's net income, arising out of Licensee's use of the ASTM Product (ii) An Authorized User may not make this Product, or (iii) Multi-Site:an organization or company with Founded by R.A.

The single hard copy print may only be distributed to others for their B. c Brinell hardness values for information only. 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. You explicitly noted in the text of the individual Documents. It is accomplished by incorporating a penetrator of slightly different contours and a heavier load spring than used in the Model B, and the 20 graduations on the dial indicator cover the range between 20 and 100 on the Rockwell B Scale.
