Frequently Asked Questions (FAQ)
Q
What raw materials are used in the transition bar?
We utilize high-grade T2 Copper paired with 1060 or 6063 Aluminum to ensure exceptional electrical conductivity, mechanical durability, and thermal performance.
Q
How are copper and aluminum bonded together?
We employ advanced explosion welding or friction welding processes. This ensures a tight molecular metallurgical bond that prevents cracking, separation, or delamination under high mechanical and thermal loads.
Q
How does this product prevent galvanic corrosion?
The seamless composite interface eliminates microscopic voids, while surface finishes such as tin plating, nickel plating, or natural oxidation protection shield the joint from oxidation and electrochemical corrosion in harsh environments.
Q
Can I order custom sizes, hole patterns, and shapes?
Yes, OEM and ODM customization is fully supported. We can customize dimensions, thickness, bending angles, hole diameters, pitch spacing, and plating according to your technical drawings.
Q
What is the minimum order quantity (MOQ) and delivery lead time?
The standard MOQ is 10 pcs for custom shapes and 5 pcs for prototypes (negotiable). Production lead time typically takes 5–7 days for simple configurations and 7–15 days for complex profiles.
Q
What operating temperature range can the transition bar withstand?
The transition bars are engineered to operate reliably in ambient temperature ranges from -40°C up to +125°C, making them suitable for demanding industrial and outdoor energy systems.
