Music Wire

Music wire, also known as piano wire or spring wire, is a high-carbon steel alloy famous for its high tensile strength and high elastic limit. Music wire derived its name from one of its most popular applications, piano strings. However, this versatile steel alloy has many different high-stress applications. The components that make this material type include Carbon (C) and Manganese (Mn). The maximum temperature it is able to resist is of 250º Fahrenheit (121º Celsius) and it is not corrosive resistant so if you wish to use this material type in a moist or corrosive environment, you might want to have the springs go under plating.

Music wire has high tensile strength, high ductility and excellent fatigue life. Our music wire meets the latest revisions of ASTM A228/A228M-16._x0007_Type I : wire shall be directly drawn from either as-rolled rods or from air patented rods or wire to the final wire diameter._x0007_Type II : wire shall be drawn from either patented rod or patented wire to the final wire diameter. All patenting is not allowed.

ASTM A228/A228M-18 Standard Specification For Steel Wire, Music Spring Quality This specification covers high quality, round, cold-drawn steel music spring quality wire for the manufacture of springs subject to high stresses or requiring good fatigue properties. The steel shall either be ingot cast or strand cast. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, sulfur, and silicon. Steel specimens shall also undergo tension test, wrap test, and torsion tests This specification covers two types of round, cold-drawn steel music spring quality wire, uniform in mechanical properties, intended especially for the manufacture of springs subject to high stresses or requiring good fatigue properties.

ASTM A228 music wire is a carbon (non-alloy) steel formulated for primary forming into wrought products. Cited properties are appropriate for the cold worked (strain hardened) condition. ASTM A228 is the defining standard for this material. K08500 is the UNS number. It has the highest tensile strength among wrought carbon or non-alloy steels. In addition, it has a fairly low ductility and a moderately low thermal conductivity.

Music Wire Spring Properties Definition

Wire spring which is manufactured using Music Wire; the American Standard of Trade and Measure (ASTM) for this material type is A228. It is a high carbon spring steel and it is the most commonly used. It offers uniform tensile strength which, when coupled with a good wire spring design, will offer many thousands of cycles of spring life. Used to manufactured several types of wire spring types.

Table of Music Wire Properties

Music Wire Spring

A spring made of music wire can resist the maximum temperature of 250ºF (121ºC). minimum tensile strength between 230*10^3 and 399*10^3 psi, its modulus of elasticity is 30*10^6 psi, and a rockwell hardness of C41-60. This specific material type will NOT resist a corrosive environment for it shall not be exposed to a moist/humid atmosphere.

Music Wire ASTM A228 is the most common and economical material type. This material type is also very basic which is why it runs the risk of rusting in corrosive environments or burning under very high temperatures. This is why we have provided you with the Music Wire Spring Properties chart, so that you may see if music wire will work for you or if you must go with a more exotic material type.

Our spring calculator includes Music Wire ASTM A228 as one of the material types you may use to generate a spring design. Whether it is a music wire compression spring, music wire extension spring, or music wire torsion spring; the above values shown on the table are part of the spring calculation software so that all of the values, like spring rate and maximum safe travel, are highly accurate. This way, you’re able to generate a music wire spring design and know which are its capacities and its limitations.

The spring calculator is also programmed to provide you with an instant quote if you use either Music Wire ASTM A228 or Stainless Steel 302 A313. As you enter your spring dimensions, pick either one of these material types, and click on “Calculate”, the calculator automatically takes all of the music wire spring properties and generates a live spring quote so that, not only do you get to work on your design, but you also get to buy it once you’re done. This isn’t it, though. Spring Creator will additionally provide you with stock spring suggestions in case you’re interested in buying small quantities of springs.

Last, but not least, generate a live blueprint of your music wire spring design. It is a live drawing made in proportion to the inputs you entered. You may email it to yourself or request a quote in case your parameters were out of the instant quoting range and the spring calculator didn’t automatically provide you with one. The file you will receive in your email will be in PDF format. It will include the music wire spring’s full analysis as well as the instant quote and the stock spring suggestions.

Use high carbon steel alloy music wire for applications that demand high strength and durability, such as springs, jewelry and piano and guitar strings. Music wire can withstand high tension and rugged use and still last a long time. Also find spring steel in smaller thicknesses to help fabricate lockpicks, spring clamps, antennas, and small aircraft landing gear. today for high-quality music wire in a variety of thicknesses and tensile strengths.

Benefits of Music Wire Compression Springs

Music wire is a frequently used material for compression springs because it can bear repeated heavy loads while maintaining its shape and elasticity. There are many benefits associated with music wire, including:

High tensile strength

High elasticity

Affordability

Availability

Easily worked

Limitations of Music Wire Compression Springs

Although there are many benefits of choosing music wire compression springs, this material does have its disadvantages. Music wire compression springs should not be used in extreme temperatures, and they can give way under shock loads. Our team of specialists can help you decide if music wire compression springs are the right choice for your application.
