Product Description
Our tin plated C11000 high conductivity copper busbar combines the superior electrical performance of 100% IACS copper with a uniform electro-tin plating that delivers exceptional corrosion protection. Designed for power distribution cabinets, control panels, and electrical enclosures where humidity, condensation, or mildly corrosive atmospheres are a concern, this busbar ensures reliable long-term performance without conductivity degradation.
- 100% IACS Base Material: The C11000 copper substrate delivers full rated conductivity before plating, ensuring your distribution system operates with minimal joule heating and voltage drop across all busbar connections.
- Uniform Electro-Tin Plating (3-8 μm): Applied via precision electroplating to ASTM B545 standards, the tin layer prevents copper oxidation while maintaining excellent contact resistance characteristics at bolted joints and terminal connections.
- 96-Hour Salt Spray Certified: Independently tested to ISO 9227 neutral salt spray (NSS), our tin plated busbars withstand 96+ hours of continuous salt fog exposure without red rust formation, confirming suitability for coastal and tropical installations.
- Precision 6x50mm Cross-Section: Tight dimensional control ensures consistent fit in standard distribution cabinet busbar supports and insulation systems.
- RoHS and REACH Compliant: Full EU regulatory compliance documentation provided with every shipment, simplifying import clearance and end-user acceptance in regulated markets.

Bare copper busbars naturally oxidize over time, forming a resistive surface layer that degrades contact quality at bolted connections. Tin plating provides three essential benefits: it prevents oxidation at the current-carrying interface, it maintains consistently low contact resistance throughout the product's service life, and it enables visual inspection of connection quality during commissioning and maintenance.
For installations in tropical climates, coastal regions, or industrial environments with airborne contaminants, the corrosion protection offered by tin plating is not a luxury but a reliability requirement. Our plating process ensures full coverage on all surfaces, including edges and drilled holes, delivering dependable protection at every connection point.
