Music Wire Spring Constant

Iano wire is intended to vibrate hence their material selection and design results in a relatively low spring constant which cannot be readily altered after the fact.

Music wire spring constant. Calculation of spring force at a given length is travel s r. Music wire is cold drawn. Music wire springs can withstand high load stresses compared to other materials which makes this material best suited for cyclic applications. Spring constant depends on several values wire diameter spring diameter number of coils the choice of material also plays an important role in coil compression spring design shear modulus is a variable in spring constant of coil compression spring.

Music wire is the toughest and most widely used of all spring materials for small springs. Although this material is versatile it s not recommended for service temperatures above 250 f 121 c. High carbon spring wire includes music wire astm a228 also known as spring steel and hard drawn astm a227. The formula to figure out your spring constant from a known load and distance traveled is.

Calculate a required spring constant the other way to calculate the extension spring constant on your spring is if you know the load you want to achieve at a certain distance traveled. Their rockwell hardness may vary between c31 and c60 depending on the high carbon spring wire type and the formula in which the material type is made. There are many benefits associated with music wire including. Music wire is cold drawn and it has a high and uniform tensile.

A spring is compressed 16 mm and the spring constant is 3 n 16 mm 3 n 48 n a spring that travels 16 mm thus produces 48 n which equates to approx. Differences between music wire and chrome vanadium stainless steel applications. It has the highest tensile strength and can withstand higher stresses under repeated loading than any other spring material. Rate load initial tension distance traveled for example.

Calculate a required spring constant the other way to calculate the extension spring constant on your spring is if you know the load you want to achieve at a certain distance traveled. Fn for spring steel music wire is approx 12 stronger than fn for the exact same model in stainless steel. M s spring company s music wire springs meet astm a228 standards. 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.

These material types are made from different portions of carbon c and manganese mn.
