Different Kinds Of Coil Winding Design You Must Know

coil winding design

Coil winding technology is an integral part of modern medical devices. Since the miniaturized devices require connectivity, micro coil winding design based on copper wire has become prevalent. The thickness of the coils is as less as 8 microns which are even thinner than the size of the human hair.

The materials of which the micro coils are generally made of are:

• Aluminum
• Copper
• Titanium
• High purity elements.

As per the parameters being listed out, the manufacturers make their own coils that eventually as per quality standards. Enough precision and quality of the coils are maintained since they are used in medical technologies.

Let us explore in detail about the various materials that are used for the manufacture of the coil winding.

Features of different materials used


One of the extensively used raw materials when it comes to making micro-coils. The micro-coils use copper since they have higher conductivity, reliability and excellent physical properties. The durability of the material gives them an upper hand compared to the other raw materials.

Stainless Steel:

Using stainless steel as one of the raw materials is due to their heat resistance nature and anti-corrosive nature. The recyclability of steel makes it a better alternative to copper. Though the cost might pose a challenge, yet using them in specific applications is always a better choice. In applications where corrosion could be a potential problem, stainless steel can be used.


The lightweight of the aluminum play a major role in making them a great resource for more micro-coil windings. In the case of equipment that requires portability, they find a greater application. But, the main problem is that they are expensive, thus are not used extensively.

Precious elements:

Elements like gold and silver play a major role when it comes to medical technology. The rare elements are resistant to chemical changes and are highly conductive in nature. It is one of the reasons why they are used in medical applications. Yet, their use is in a limited sphere to the exorbitant cost of the metals. As the metals are rare, only in cases when direct contact with the body is required, as these precious metals used.


The last element which is also used in the coil winding design is the titanium. A highly resistant metal, its great strength, and excellent conductivity make it a unique metal. Used in specific areas in the domain of medical technology, they find applications in the dental and medical domains.

Changing trend in medical technology

As medical technology is shifting towards the use of micro-coil windings, it is important to know the manufacturers of the same. Since it is a medical application it becomes important to maintain quality standards and customization of the product. Micro-coil windings are thinner than the size of the hair, hence extreme precision and excellent manufacturing skills are needed to get it done. Instead of delaying it further, it is better to implement it in your clinics soon.
