and lead was used for tools‚ weapons and pipes. Iron is much harder than bronze. * Modern Age (1 CE – Present) – main metals are iron‚ aluminium and steel‚ which were used for pipes‚ buildings‚ transport and electrical cables. This is the age where technology of iron and steel improved. Around the 1880’s‚ there was a significant move towards new alloys and metals‚ including tungsten steel (cutting tools)‚ manganese steels (railway lines and digging tools)‚ silicon‚ chromium‚ nickel and vanadium
