It is not recommended to use air as the atmosphere of the heat treatment for electric components, because an intensive black oxide film will be formed on the surface. Heat treatment of beryllium copper is usually performed in an inert gas atmosphere, such as nitrogen, carbon dioxide or argon. for shorter time or at higher temperature. Although the required time to heat up the temperature to 315☌ or to cool down to room temperature gives little influence on the properties in case of standard heat treatment conditions, it must be checked carefully when other conditions are applied, e.g. ![]() When the volume or weight of parts to be heat-treated in a furnace is relatively large, it is important to ensure that the temperature of the parts is kept at 315t for 2 to 3 hours by directly attached thermocouple. The retention time must be counted after the material has reached 315☌. Standard heat treatment conditions for beryllium copper alloy 25 age hardenable material are temperature of 315*C and retention time of 2 to 3 hours. This is shown by age hardening curves in Fig. The increase in the mechanical properties of beryllium copper can be controlled through the heat treatment conditions and the cold rolling reduction rates, i.e. Aging Conditions and Aging Furnace, Shrinkage (Alloy25) Aging Conditions and Aging Furnace ![]()
