Conclusion
This task described the processes for identifying the physical and
mechanical properties of various metals, and provided an explanation

basis for the next task, which will describe the processes for
identifying the physical and mechanical properties of various metals,
and also describe the use of the hardness tester, chemical analysis,
and bench grinder to identify various metals.
