Music wire is a common high-carbon steel alloy used for spring manufacture. It is cold drawn and offers uniform tensile strength.
Music wire springs are not recommended for applications where the temperature exceeds 121º C (250º F.)
Music Wire is highly magnetic.
Stainless Steel Type 302 exhibits good corrosion resistance for all applications. Lee Spring passivates all Stainless Steel Stock Springs to remove contaminants and improve resistance to corrosion. Stainless steel springs are not recommended for applications where the temperature exceeds 260º C (500º F). Type 302 stainless steel is slightly magnetic. Surface of stainless steel may have a residue of nickel on the surface. This is normal and will not affect the function of the part.
Stainless Steel Type 316 exhibits superior corrosion resistance due to the presence of molybdenum in this alloy. Lee ultrasonically cleans all Type 316 Stainless Steel Stock Springs, as well as passivating them as described above. It also resists chloride attack and is often selected for use in marine atmospheres. Continuous use of 316 in 800 – 1575°F range not recommended but often performs well in temperatures fluctuating above and below this range
HEFTY™ Die Springs are manufactured using either Music Wire or Chrome Silicon.
Stress Relief
All springs are stress relieved to remove coiling strains.
Plating
All Lee Music Wire and Oil Tempered Standard and Heavy Duty Stock Springs are zinc plated in accordance with specification ASTM B633 Class Fe/Zn 5 Type III (.0002” thick with clear chromate) and baked for hydrogen embrittlement relief. All Lee Music Wire Instrument Compression and Extension Springs are zinc plated or tin coated without supplemental zinc plating. All Lee Music Wire Continuous Length Extension Springs are furnished with a light oil coat.
All Lee Spring Stainless Steel Standard and Heavy Duty Stock Springs or Instrument Series Springs are passivated in accordance with specification ASTM A967 (supercedes QQ-P-35).
Nickel Plated Music Wire
Lee Spring manufactures its unique line of battery springs using nickel coated music wire. Since most alkaline batteries have nickel plated containers, a nickel coating for the contacts is preferable. The use of similar materials removes the possibility of galvanic corrosion and aids in wear resistance. Nickel will also tend to wipe and aid in breaking down the oxide that can form on the battery contact surface. In addition, a nickel coating will provide general corrosion resistance and is an excellent conductor of electricity.
Custom Spring Materials
include stainless steel (17-7 and 316), high carbon steel wire, alloy steel or music wire, nickel base alloy wire, brass, and hard drawn wire. Exotic metals and their alloys with special properties and applications can also be specified for custom compression springs. They include such materials as beryllium copper, phosphor bronze, elgiloy, hastelloy®, inconel 600, 718 and x750 and many others.
