What is Music Wire?

Posted on May 31, 2017

Music wire is a highly versatile type of wire, however as the name implies, it is best known for only one of its uses. It is made from high carbon steel, making it ideal for high-stress applications such as piano strings. In this particular application, the wire is stretched to an extreme amount of tension and it is continuously struck by hammers to create the piano’s sound. This example provides a great illustration of the strength of music wire.

In addition to its high and consistent tensile strength, music wire is also able to handle severe bends. These characteristics make this type of wire a widely used choice for coiled springs. Another advantage music wire offers is its cost, which is comparable to the lower quality carbon steels, especially when the wire diameter is small and the quantity needed is low.

For all of its advantages, there are some drawbacks to using music wire:

Lack of corrosion resistance – application of a protective coating such as zinc plating is an option however it will just slow the corrosion.

Inability to withstand high temperatures – For high temperatures above 250 degrees F, 302 stainless steel is a better option.

Loss of high tensile strength as the wire diameter increases – In most cases spring designers will recommend oil temper at these large wire diameters.

Not cost effective in low stress and large quantity applications – Hard drawn carbon steel is a better choice for large production needs and low stress applications.

When you need springs, it is best to speak with an experienced spring manufacturer that can help you determine which type of spring and which material will provide you with the best application fit and performance. If you are not sure whether or not music wire springs are the best choice for your application, contact us to speak with one of our spring experts.

Understanding Steel Springs

Posted on April 28, 2017

A wide variety of industries depend on steel springs. Some of these include electronics, medical, military, automotive, oil and gas, telecommunications, textiles, agriculture, and aerospace. Applications for steel springs include power equipment, fitness machines, retractable tape measures, timing devices, gardening equipment, toys, as well as a variety of safety mechanisms.

Steel springs are fabricated from tempered wire. Different wiring drawing processes are used to create distinct wire diameters. Starting as a 100 to 1000 pound bar about 2” in diameter, the wire is continually drawn through smaller dies, reducing it to the required diameter and enhancing the tensile strength of the metal.

The most widely used steel types used in the fabrication of steel springs are carbon steels and stainless steels. Music wire is commonly used due to its high carbon content, and results in better quality and more uniform steel springs. A drawback to the use of music wire and other carbon steels is that they rust.  Stainless steel is a better option for steel springs that will be used in wet environments, due to the corrosion resistance of stainless steel. When creating springs from stainless steel, it is important to keep in mind that some types of stainless are slightly magnetic in spring tempered form.

W.B. Jones manufactures a variety of steel springs to meet a variety of needs:

  • Compression Springs
  • Extension Springs
  • Torsion Springs
  • Custom Springs

We offer expertise and capabilities that include the fabrication of steel springs made to precise specifications.

Understanding Extension Springs

Posted on March 9, 2017

Extension springs are commonly used  in automotive assemblies, garage door mechanisms, hand tools,  toys, trampolines, washing machines, farm equipment, and more. They are available in a wide range of sizes, from tiny extension springs for medical devices to larger sizes for industrial machinery. Extension springs are attached to other components on both ends. As the components move apart, the spring provides a force that brings them together again.

By design, extension springs are engineered to absorb and store energy by offering resistance to a pulling force. When the extension spring is slowly stretched the tension force is resisted because the spring is attempting to return to its coiled resting position. The farther the spring is extended, the greater the degree of resistance it will have.

Extension springs are usually cylindrical in shape and closed wound. End styles vary based on the application for which they are being used. By varying the diameter of the coil, wire thickness, and length of the extension spring, they can be designed to accommodate a variety of loads and application conditions. As with most spring types, extension springs can be fabricated from a number of different materials to suit individual application needs. Temperature, stress, and corrosive environments are examples of factors that will influence material selection.

W.B. Jones is a specialized and experienced manufacturer of high quality springs. Our expertise and capabilities include the fabrication of custom extension springs made to precise specifications. We assist our customers in ordering custom extension springs that meet all application requirements and work within the customer’s  established budget.  All W.B.

Selecting the Right Spring End Type for your Project

Posted on February 13, 2017

A wide range of spring end types are used in modern spring design. The spring end type you choose will depend on the job the spring will be doing. In some cases a spring will have two different end types. To best select the right end type or types for your spring, you’ll need to understand each end type and how they function. A spring’s end type affects its pitch, solid height, number of active and total coils, free length, and seating characteristics of the spring. Selecting the right end type for your springs begins with identifying the basic end types available for the different types of spring design:

Extension Spring End Types

The two end types most commonly used with extension springs are hooks and loops. Hooks have a gap, while loops are fully closed all the way around. Typically stock extension springs are made with loop ends. If a hook is required, a gap is cut in the loop to create the hook. Hooks and loops can be customized to meet specific application needs. The most commonly used end styles for extension springs are crossover, machine style, side style, and double loop ends.

Understanding extension spring end types

Compression Spring End Types13

The two common end type options in compression springs are open and closed. With each of these, either ground or not ground ends can be specified. A closed or squared off end type is most often used for compression springs. For closed ended springs, the space between the last two coils is so minimal the coils actually touch and it sits flat. In contrast, open ended springs are not squared off and tend to need some type of support, such as a rod. Open ends are usually only used in special applications. Grinding the ends of compression springs helps springs sit more flat to reduce buckling.

Understanding compression spring end types

See compression spring end types video

Torsion Spring End Types

When it comes to torsion springs, the most typical and versatile end type is a plain straight leg, with no bends. Customized designs can be created for applications that require a torsion spring with bends.

3 Common Adjustments to Prevent Extension Spring Failure

Posted on February 2, 2017

Spring failure can cause costly and damaging problems for your extension spring application. In most cases of extension spring failure, the cause is stress or force that exceeds what the spring is designed to handle. For example, extension springs that are designed for strength usually have reduced elasticity, and will fail if stretched too far.  The spring breakage can occur at the ends or within the body. Other reasons for failure besides a flawed spring design are unforeseen environmental issues and improper installation.

Characteristically, extension springs are more vulnerable at the ends than within the body. When the loops or hooks are formed, the wire is bent upward and the diameter of the ends is slightly decreased. This bend and reduced diameter create a considerable concentration of stress. A well-engineered spring will take this concentration into account as it leads to premature failure.

If extension spring failure occurs due to overstressing, the spring design probably needs to be adjusted. These three common changes can decrease the likelihood of breakage:

  1. Increase the Outer Diameter
  2. Decrease Wire Diameter
  3. Add More Coils

Obtaining accurate information about what will be required of the spring while you are in the design phase will greatly reduce the chances of extension spring failure. Such information may include the required extended length to the necessary load or the full measurements of an existing spring. The more exact the details are the less likely spring overstressing and breakage will occur.

Spring Life: How Long Do Springs Last?

Posted on December 13, 2016

Spring life expectancy depends much on the application in which the spring is being used. Factors such as force involved, materials used, and environmental conditions all have an impact on spring life. The design of the spring also impacts how long the spring will last. When premature spring failure occurs, it is typically due to a flaw in the design of the spring.

In many cases, springs are not properly designed for the job they are doing, which leads to reduced spring life. The application of more stress or force than the design allows can lead to spring breakage or cause the spring to take set. For instance, a spring that is designed for high strength will have minimal elasticity. Damage to an extension spring can occur in the body or at the ends if the spring is extended too far.

Spring life will also be impacted by the quality of the spring wire used to fabricate them. Low quality wire can have surface or inner defects, which curtail spring performance by reducing spring fatigue strength and increasing the possibility of breakage. Choosing springs developed from high grade materials will enhance spring performance and extend spring life. It is also important to choose the right spring material for the application. For example, hard drawn wire is most commonly used for low stress applications, while high stress applications need a stronger choice, such as music wire. Since hard drawn wire is cheaper than music wire, hard drawn may be a better choice if high strength is not required.

For many applications, achieving optimal spring life requires a custom spring design. The right spring supplier will assist you in evaluating your process and determining the best, most-cost efficient design for your project.
