Metals having low melting point can be used as filler metal for joining copper Bus Bars. Silver brazing is a joining process and popular for joining or bonding non-ferrous base metals due to its very good general capability such as low melting point, high strength, good plasticity and perfect electrical and corrosion-resistant features. However, the conductivity of the brazed joint will be much lower than the base copper; therefore the innovative copper products by Oriental Copper, such as Twist Bar and Bended Vertical Elbow, will be an alternative to the brazed joint replacement without significant change in the conductivity.

Good condition of contact surfaces of a joint are important for high conductivity and efficiency. The surfaces of copper should be flat and without and space in between the contact surfaces, this enables optimum current flow, resulting in less generated heat or power loss.
