Copper bending is a process of deforming copper sheets or bars by applying a force to them, it is often used to create custom-shaped components such as shunt resistors or bus bars. Bending copper can be done using a press brake or a bending machine to create complex shapes or forms.

Manganese shunt is a reference to a shunt that is made of a metal alloy that contains manganese. A shunt is intended for high-temperature applications, the manganese alloy resistors have high-temperature stability, corrosion resistance, and lower cost compared to other alloys.

It is important to note that the Manganese shunt is not as common as the copper shunt, it is usually used in special applications that require a shunt to be used in high-temperature environments. The copper shunt is the most common type, as it has high conductivity, and corrosion resistance and it is relatively inexpensive.
