Abstract: This project investigates to seven alloying objects, selected from National Museum of Iran. In this case try to after studying historical valid texts “compositions” and production technology of old objects identify with modern fine “characterizations” (Analysis) and so to corrosion products. Five metallurgical tests include DT& NDT that section NDY applies in special field for first time. Metallurgy tests include: metallography (L.M&SEM) and characterization findings, verify elements of alloy and production technology. The alloying of these objects “High Tin Bronze”, (Cu75% - Sn25%), and although identical characterization, their product technology are different in metallography observation, so that mechanical and heat treatment, present each one of them, special metallurgic properties and this fact certificates by its phase diagram. Analyze of corrosion product presents that these objects expose in different conditions and methods of conservation based on result tests.
