Pure Copper Busbar – Process & Quality Assurance Statement
Our pure copper busbars are manufactured to deliver maximum conductivity and reliability in high-current electrical systems where efficiency and durability are essential.

Key process features

Production follows a controlled rolling and finishing process to ensure uniform properties and excellent surface quality:

●Raw Material Selection: Only certified high-purity electrolytic tough pitch copper cathodes (≥99.9% Cu) are used.
●Hot Rolling: Ingots are hot rolled into wide slabs, refining grain structure and achieving initial thickness.
●Cold Rolling: Multiple passes produce final thickness with smooth surfaces and tight dimensional tolerances.
●Annealing: Protective atmosphere annealing optimizes ductility and conductivity while relieving internal stresses.
●Precision Fabrication: CNC cutting, punching, bending, and edge chamfering create exact lengths, hole patterns, and custom shapes.
●Optional Tin Plating: Uniform tin coating is applied for enhanced corrosion resistance and improved solderability.
●Final Cleaning & Packaging: Busbars are thoroughly cleaned and securely bundled with protective interleaving to prevent damage during global shipping.

Quality control system

● Full traceability from copper cathode to finished busbar
● Material test certificates and conductivity reports provided with every shipment
● Sample retention ≥3 years for third-party verification (SGS, BV, TÜV, etc.)
● 100% inspection of critical parameters:
• Chemical purity and conductivity (eddy current testing; typically >100% IACS)
• Dimensional accuracy (laser measurement; typical tolerance ±0.2mm)
• Surface quality and flatness (visual + profilometer checks)
• Mechanical properties (bend and tensile testing on samples)
• Plating thickness and adhesion (where applicable; X-ray fluorescence)
● Internal standards exceed ASTM B187 requirements. Typical C11000 properties:
Excellent current-carrying capacity with minimal heat generation, Superior flexibility for tight-radius bending, Proven long-term stability in high-vibration environments.
● ISO 9001:2015 certified production ensures every pure copper busbar delivers consistent quality, efficiency, and reliability for your critical power systems.
