What is a standard nickel-coated copper conductor?
Standard nickel-coated copper conductors used in electrical applications are divided by ASTM-B355 in five classes (Class 2, 4, 7, 10, 27) representing the minimum percentage (by weight) of nickel coating with respect to that of the wire (i.e., Class 4 means that the nickel-coating weight is at least 4% of the total weight of the coated wire).
A standard nickel-coated copper conductor refers to a copper wire that has been coated or plated with a layer of nickel. This type of conductor combines the excellent electrical conductivity of copper with the beneficial properties of nickel, such as corrosion resistance and improved solderability.
The nickel coating serves several purposes:
Corrosion resistance: Nickel provides a protective barrier against corrosion, making the copper conductor less susceptible to oxidation and degradation in various environments. This is especially important in applications where the wire may be exposed to moisture, humidity, or other corrosive elements.
Solderability: The nickel coating enhances the solderability of the copper conductor, facilitating the soldering process during assembly or installation. It helps to prevent the formation of copper oxide on the surface, allowing for better solder wetting and improved electrical connections.
Wear resistance: Nickel is a relatively hard and durable material compared to copper. The coating provides a protective layer that can help withstand abrasion, friction, and mechanical stress during handling or operation.
Standard nickel-coated copper conductors are commonly used in various applications, including:
Electrical and electronic wiring
Printed circuit boards (PCBs)
Connectors and terminals
Coils and inductors
RF and microwave components
Automotive wiring harnesses
Aerospace and aviation applications
It's worth noting that the thickness of the nickel coating can vary depending on the specific application and requirements. Thicker nickel coatings may offer higher levels of corrosion resistance and durability, but they can also affect electrical conductivity to some extent.
