The temperature needed to bend aluminum depends on the specific alloy and thickness of the aluminum being used. Aluminum alloys have different melting points and thermal properties, which affect their response to bending. Generally, aluminum alloys can be bent at temperatures ranging from 200°C to 450°C (392°F to 842°F).
For example, the commonly used aluminum alloy 6061 has a melting point of approximately 580°C (1076°F). However, the temperature required to bend it is typically lower. In practice, aluminum alloys are usually heated to a temperature range of 300°C to 400°C (572°F to 752°F) before bending.
It's important to note that bending aluminum at elevated temperatures requires careful consideration of the specific alloy and its heat treatment history. Some alloys may have specific temperature ranges or heat treatment processes that need to be followed for optimal bending results. It's always recommended to consult the material specifications or seek guidance from experts when working with aluminum and determining the appropriate bending temperature for a particular alloy and thickness.
