tin is an extremely soft metal..one of the constituents of soft solder...
metal containers are not made from tin...but they may be made from tinplate.
this to prevent oxidisation of the underlying low grade steel...and being a thin layer of only several microns...
modern containers sometimes have a further layer of printed decoration added. using a process similar to magazine printing, but using a polymer film..
hardness measurement on ultra thin layers is problematical....jim
