    Frequently Asked Questions (FAQ)
    Why is a copper-aluminum transition bar necessary for electrical connections?
    Directly connecting copper and aluminum can lead to galvanic corrosion due to the difference in their electrochemical potentials. A copper-aluminum transition bar provides a secure bimetallic interface, preventing corrosion and ensuring a long-term, stable, and low-resistance electrical connection.
    What processing technology is used to bond the copper and aluminum?
    We utilize advanced explosion welding and friction welding compound processes. These technologies form a molecular-level bond between the T2 copper and 1060/6063 aluminum, preventing cracking, delamination, and ensuring high mechanical strength.
    Can I request custom sizes, shapes, and hole configurations?
    Yes, we offer comprehensive custom services (OEM & ODM). You can customize the dimensions, thickness, bending angle, drilling patterns, and surface plating (such as tin or nickel plating) according to your technical drawings.
    What is the typical lead time for custom orders?
    The lead time depends on the complexity of the design. Typically, simple shapes take 5–7 days, while more complex profiles or customized configurations require 7–15 days.
    Do these transition bars support high-temperature environments?
    Yes, our copper-aluminum transition bars are designed to operate reliably within a working temperature range of -40℃ to +125℃, making them suitable for demanding industrial and electrical environments.
