Solenoid Coil Prices by Type

Solenoid coils can be categorized into various types based on their structure and applications. Different types of coils show significant price differences. Below is an analysis of common solenoid coil types and the factors influencing their prices:

Standard Wound Coil

This type of coil is usually made by winding ordinary copper wire with a simple structure, suitable for general low-power and low-frequency applications. Due to its mature manufacturing process and relatively low raw material consumption, it has a relatively low price and is suitable for large-scale standardized production.

Dense Wound Coil

Dense wound coils have more turns and tighter winding, often used in applications requiring higher magnetic field strength. Due to the more complex winding process, increased material usage, and higher manufacturing difficulty, their price is about 20%–40% higher than that of standard wound coils.

Multi-layer Coil

Multi-layer coils have a complex structure, composed of multiple layers of copper wire wound together, used in high-performance electromagnetic equipment. Their manufacturing process demands are high, with strict insulation material and coating requirements. The price is significantly higher than single-layer coils, usually more than 50% higher than standard wound coils.

Flat Wire Coil

Flat wire coils use flat copper wire winding, which reduces resistance and heat generation, making them suitable for energy-efficient equipment. Due to the higher cost of flat wire material and more demanding winding processes, their price is typically about 30% higher than circular wire coils of the same specifications.

Special Function Coil

This category includes coils that are high-temperature resistant, waterproof, corrosion-resistant, or equipped with special magnetic cores. Because they use special materials and processes, their price is significantly higher than ordinary coils and can be several times that of standard coils. The exact price depends on the materials used and design complexity.

In summary, the price range of solenoid coils varies greatly depending on materials, manufacturing processes, and performance requirements. When purchasing, it is important to balance cost-effectiveness with specific application needs and select the most suitable coil type.If you want to choose a cheap solenoid valve coil, you can refer to: How to choose a cheap solenoid valve coil.
