Stranded Bare Copper Wire – Copper nickel alloy, which has low electric resisitance, good heat-resistant and corrosion-resistant, easy to be processed and lead welded. It is used to make the key components in the thermal overload relay, low resistance thermal circuit breaker, and the electrical appliances. It is also an important material for electrical heating cable. It’s similar as s type cupronickel. braided bare copper wires
The more composition of Nickel,the more silver white the surface to be.
Size dimension range:
Wire: 0.01-10mm
Ribbons: 0.05*0.2-2.0*6.0mm
Strip: 0.05*5.0-5.0*250mm
Bar:10-50mm
Copper nickel alloy series:
CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
Also named NC003, NC005, NC010, NC012, NC015, NC020, NC025, NC030, NC035, NC040, NC050.

This Bare Copper Conductor Wire is suitable for use in crafts or for electrical grounding wire use. This single-strand wire is annealed for improved ductility and meets QQ-W-343 standards for uninsulated copper wire. It also meets ASTM B3 standards for annealed copper wire and complies with Restriction of Hazardous Substances (RoHS) regulations. This copper wire is suitable for use in crafts such as jewelry and weaving or for uninsulated wiring applications.

Electrical wire carries an electric current or grounds an electrical device. The amount of current a wire can carry is proportional to its size (gauge), and the wire is generally sheathed with coatings and coverings to insulate and protect it from moisture, chemicals, heat, and abrasion. Copper is the primary material for electrical wire, but alloys are sometimes used to increase its strength or its resistance to chemicals and the environment. Wire can be composed of a single strand or of many smaller strands, depending on its use, and is typically annealed to improve its ductility. Electrical wire is commonly used in industrial, electronic, and automotive applications.
Application of Bare copper wires play a critical role in the manufacturing of overhead transmissions and distribution applications, whereas stranded conductors are generally used for uninsulated hook up, jumpers, and grounds. It is also well suitable for the making of the wires used for electrical grounding.
