Impact Strength of steel and Aluminium.

Impact Strength of steel and Aluminium.

(OP)
Any one can give the Impact strength value of general Application steel and Aluminium(J/m).Please let me clarify which one would absorb maximum amount of impact energy and why?

RE: Impact Strength of steel and Aluminium.

You can go to www.matweb.com and type in your specific material to look up the value for the Charpy Impact strength.

Thanks Mr.Swertel, It’s really a good web site, I got all my required data. I found the impact value of metal are given in J but for Polymer in J/cm, Can u give me some idea, How to get metal(steel) impact value in terms of J/cm.(cm is meant for thickness of the specimen)?

RE: Impact Strength of steel and Aluminium.

You need to consult the actual test method used for obtaining the fracture energy results.  The test method will explain what the sample size is supposed to be, and how to calculate the fracture energy.  Charpy testing is most commonly used for testing metals, and Izod testing is most commonly used for plastics.  Differences exist in the details of specimen size, notch geometry (size, radius, etc.), so they may not be exactly compatible.

In general, for a given volume of material, steel will absorb more energy than aluminum or plastic, which is indicated by the general impact test results.  Remember that for a given volume, though, aluminum weighs only 1/3 as much as steel, and plastic will be only ~ 1/7 the weight.  This has significant implications for anything other than the standard impact test.
