For nearly 5,000 years, copper was the only metal known to man. Today, it remains one of the most widely used metals.

Copper is an excellent conductor of electricity and heat. Precision flat copper wire is versatile, making it ideal for use in a wide variety of industries, such as:


Flat, copper wire applications have soared in recent years due to the rising production of consumer electronics. Durable, lightweight, and compact, flat copper wire is ideal for use in smartphones, laptops, tablets, and other devices.


Flat copper wire’s flexibility and ability to resist heat and vibrations make it an excellent choice for the automotive industry. It’s used in cars, trucks, and buses due to its unique electrical and mechanical properties. You can find flat copper wire in automotive wiring harnesses, electronic braking systems, and other vital vehicle systems.

Medical Equipment

Flat copper wire is also used in medical equipment, such as ECG machines, defibrillators, and other monitoring devices. Its slender profile allows for easy navigation. Medical professionals use flat copper wire to ensure patients are accurately monitored and fitted with lifesaving equipment.


The aerospace industry uses flat copper wire in multiple applications, including satellites, communication devices, radar systems, and avionics. The flat shape makes it ideal for fitting into small spaces without interference or loss of signal.


Flat copper wire is also used in general electrical applications, like transformers and inductors. Its unique shape allows for better heat dissipation, which can lead to improved efficiency and lower energy use.

Precision flat copper wire has many advantages over other materials. It has excellent electrical conductivity, high thermal conductivity, and good corrosion resistance. It can be easily formed into different shapes and sizes to meet specific applications.

At Radcliff, we precision roll our flat copper wire from round wire. This process offers numerous advantages over the traditional slit strip product. For example, flat wire can be produced in longer continuous lengths which result in larger coil packages, eliminating welds and reducing set up time for our customers. Rolling flat wire typically has burr-free edges, which can be advantageous in applications where deburred edges are required.

Finally, a word of caution! When deciding between flat wire or slit strip (which is a metal strip slit from a wider coil), be sure to consider factors such as packaging, current capacity, material availability, width, thickness, and tolerances. Ultimately, your specific application requirements should direct your choice.

Radcliff Wire hasn’t been around as long as copper has, but we’ve learned a great deal about copper wire – and all other types of wire – since opening our doors more than six decades ago.
