What Is the Difference Between Copper-Clad and Copper-Bonded Steel?

When discussing components in an electrical grounding system, terms like "copper-clad steel" and "copper-bonded steel" are often used interchangeably. Though they might seem similar, each term actually refers to different processes in which copper is applied to a steel core. This article delves into these distinctions.

Both copper-clad and copper-bonded steel incorporate a steel core surrounded by a layer of copper. This gives both materials the high tensile strength of steel, along with the corrosion resistance of copper. However, their conductivity is lower than that of pure copper, requiring adjustments in diameter and copper thickness for different applications.

Key Differences Between Copper-Bonded and Copper-Clad Steel

Forming Process

Copper-bonded steel is made through continuous electro-plating, which results in a molecular bond between the copper and steel. This technique is often used for steel products like ground rods and solid conductors. The thickness of the copper layer is crucial and typically measured in mils.

Copper-clad steel involves applying copper strips over a steel core using heat and pressure. The copper’s thickness is adjusted according to the required conductivity level, which is often around 40% of pure copper.

Performance and Applications

Copper-bonded steel is primarily used in ground rods, solid wires, and solid conductors. It is highly valued for its robust molecular bond and consistent performance. Conversely, copper-clad steel finds frequent use in stranded and solid conductors. Both types are frequently utilized in environments requiring theft deterrence due to their high tensile strength and similar corrosion resistance to pure copper.

Application in Products

Understanding the material differences is crucial for selecting the right type of ground rod for connecting electrical installations to the earth. Ground rods are vital for effective grounding in electrical systems. Companies like nVent ERICO provide dependable ground rod solutions, and various resources can offer additional insights into material selection.

Tin Plating of Copper Busbars - What You Need to Know

Tin plating is prevalent for various copper products like busbars, battery connectors, and electrical terminals due to its cost-effectiveness, conductivity, and solderability. As electrical systems advance, the demand for efficient, durable tin coatings rises.

What are Copper Busbars used for?

Copper busbars distribute high current and dissipate heat in electrical applications. Typically made from C110 copper, known for its high conductivity and formability, busbars support a range of industries from automotive to power equipment.

Why are Copper Busbars Tin Plated?

Tin plating enhances copper busbars by improving corrosion resistance, electrical conductivity, and solderability. The tin layer prevents oxidation and maintains performance better than raw copper, although it will gradually lose some conductivity over time.

Applications Across Industries

Tin-plated copper busbars are utilized in electrical power transmission, manufacturing, construction, transportation, and renewable energy sectors. The tin layer boosts reliability and lifespan by protecting against corrosion and improving conductive efficiency.

Types of Tin Coatings

When specifying tin for busbars, key options include:

• Electrolytic Bright Tin: Ideal for electrical conductivity and corrosion resistance but not for soldering.
• Electrolytic Matte Tin: Best for solderable applications, offering a functional but less visually appealing finish.
• Hot-dip Tin: Suitable for complex shapes but can result in inconsistent coating thickness.
• Tin/Lead Alloy: Used for improved chemical resistance and prevention of tin whiskers, ideal for critical electronics.

Choosing the right type depends on specific application requirements like corrosion resistance and solderability. Consulting with a plating specialist is recommended.

Benefits of Tin-Plated Copper Busbars

Tin plating offers multiple benefits including:

• Solderability: Especially effective with matte tin coating.
• Corrosion Protection: Tin offers superior barrier protection against corrosion.
• Enhanced Electrical Conductivity: Tin’s conductive properties withstand oxidation better than bare copper or aluminum.
• Thermal Conductivity: Facilitates efficient heat transfer.
• Lubricity: Naturally resists galling and reduces wear.
• Cost-Effectiveness: Affordable compared to precious metals, with efficient plating processes.

Conclusion

As industries advance, the need for efficient, cost-effective, and conductive metals like tin-plated copper busbars grows. Tin plating offers numerous advantages such as improved conductivity, solderability, and corrosion resistance. Companies like Advanced Plating Technologies, with decades of experience, can help optimize your tin plating needs for various applications.
