How Many Types of Coil Springs are there?

Coil springs or metal wonders which are used to supply support and manage the flexibility in different mechanical systems are created through a very sophisticated process. The metal is wound around a specific tool, mandrel, until the length of the coil is reached. Although all the coil springs are shaped in a helical form, the number of coils per inch can highly impact their specific characteristics.

 

1. Closed End Coil Springs

These coil springs, having closed ends, are commonly applied to compression tasks. They provide stability, but it turns out that their tips penetrate very deeply into the ground before they fail prematurely. Though they have the ability to produce stability, their tendency to soil in is their downside.

2. Volute Coil Springs

As a member of the compression coil spring family, volute coil springs feature a cone-like shape. This exclusive format makes them great for heavy loads. They are able to stand higher pressures much more than other coil springs do. Nevertheless, it should be taken into account that excessive concentrations could cause higher stiffness.

 

3. Arc Coil Springs

The load bearing capacity of the arc coil springs makes them ideal for today's vehicles and machines. Arc coil springs are contrary to open coil springs in that they are curved in the middle, taking the arc shape. They are used for this purpose to bring two objects together therefore making them move closer.

 

4. Variable Coil Springs

The coil springs with the variable coil, called also the progressive coil springs, perform their screwing function with respect to the distance. The differently arranged number turns to produce variable levels of spring compression.

 

5. Torsion Coil Springs

Torsion coil springs are exclusive in that they can bear rotational forces. A famous example is the mousetrap made by a tension coil spring. What will happen is that – energy will be kept inside the solenoid and magnetic energy will be released when the captive is set into motion.

 

6. Open End Coil Springs

Open-end coil or Tangential springs which have a pitch out to the end of their coil and are the most commonly used type of spring in automotive applications. One of the cons of open end coil springs is that they won’t stand square without a seat or other help.

 

7.  Pigtail End Springs

Spiral shaped springs with eccentrically ground pigtails are used as vibrating conveyor springs. These springs for vibrating conveyors have the unique feature of being able to be bolted to the structure and work in either extension or compression modes.


8. Music Wire Coil Spring

Music Wires are an example of material used most frequently for spring manufacturing. It can withstand the maximum temperature of 250ºF (121ºC). These springs are famous for their solidness, toughness and the ability to withstand high pressure and repeated load.

They are frequently used in many applications, such as automotive suspensions, industrial machinery and musical instruments and thus the name coined for them is "music wire."

 

9. Carbon Steel Coil Springs

The type of steel that coil springs are mostly made from is high carbon steel, a tough, springy, durable and cheap material.

This type of steel comes in two alloy grades: 1045 and 1095. Carbon steel springs are made of 1 % carbon, 0.9 % manganese content, and a fine pearlite layer structure which makes them very hard, less ductile and more brittle. This steel is very often used in machinery, springs and engineering construction.

 

10. Chrome Silicon Coil Springs

Tougher than Music Wire, a chrome silicone spring is suitable for temperature fluctuations. Unlike Stainless steel, they have slightly higher tensile strength, though not as strong as chrome silicon steel.

Nevertheless, they can be degraded under humid conditions because they rust when they are exposed to moisture. A maximum endurable temperature of 475ºF (246ºC) has been determined. This coefficient gives silicon coil springs a high tensile strength which makes them suitable for long term use in elongation.
