Flexible Copper Busbar
A Copper Nickel Busbar (CuNi Busbar) is a specialized electrical conductor made from copper-nickel alloy, typically CuNi 90/10 or CuNi 70/30 compositions. These Busbars combine the excellent electrical conductivity of copper with the superior corrosion resistance and mechanical strength of nickel, making them ideal for harsh and corrosive environments.
Manufacturing a copper nickel busbar involves several precision processes:
Material Preparation: Selection of high-quality CuNi alloy sheets or foils (commonly 90% copper and 10% nickel or 70% copper and 30% nickel).
Cutting & Forming: CNC machining or stamping shapes the busbar to exact specifications, including slots, holes, or bends.
Surface Treatment: Depending on requirements, surface plating or additional coatings may be applied to enhance corrosion resistance.
Quality Inspection: Dimensional accuracy, conductivity, and mechanical integrity are strictly tested to meet industry standards.

Nickel Plated Copper Busbars are widely used where both electrical performance and resistance to corrosion are critical:
Marine Industry: Power distribution in ships and offshore platforms where saltwater corrosion is prevalent.
Chemical Processing: Equipment and panels exposed to aggressive chemicals and corrosive atmospheres.
Heat Exchangers: Busbars in HVAC and cooling systems requiring thermal and corrosion resistance.
Power Distribution Systems: Industrial electrical panels and switchgear operating under harsh conditions.
Other Corrosive Environments: Electrical components in coastal, petrochemical, or mining installations.
Excellent Corrosion Resistance: Copper nickel alloys resist oxidation and degradation in saltwater, acidic, and alkaline conditions.
Good Electrical Conductivity: While slightly lower than pure copper, CuNi busbars provide sufficient conductivity for demanding electrical loads.
High Mechanical Strength: Nickel addition improves durability and wear resistance.
Thermal Stability: Suitable for elevated temperature applications without significant loss of performance.
Customizable Dimensions: Thickness, width, and shape can be tailored for specific installation needs.
Design considerations for Nickel Plated Copper Busbars include:
Current Load and Conductivity: Adjust cross-sectional area based on amperage requirements.
Environmental Conditions: Select alloy grade (90/10 vs. 70/30) based on corrosion level.
Mechanical Requirements: Consider bend radius and mounting methods.
Thermal Management: Ensure sufficient surface area or cooling mechanisms.
Compliance: Design to meet relevant electrical and safety standards.
