Wire Products

Medical Wire Information
Component Supply carries several wire products including: 304 stainless steel straightened wire, music wire, guide wire assemblies, PTFE guide wire assemblies, Nitinol wire, PTFE coated stainless steel wire, PTFE monofilament and lab kits. While a brief description and application examples for each of these products are provided on this page, please visit each individual product page for even more detailed information.

304V STAINLESS STEEL MANDREL WIRE is spring tempered, drawn and straightened with a bright finish. It is strong, flexible and easily welded or soldered. This wire is available in 0.001-inch increments for diameters ranging from 0.003-inch to 0.150-inch. 304 always is designated with a V (Vacuum Arc Remelted) for diameter sizes of 0.040-inch and down, but sizes larger than that may not be designated with a V.

MUSIC WIRE is straightened, hardened spring steel wire originally intended for strings in musical instruments, but now primarily used in manufacturing spiral springs. It can endure high tension and stress repeatedly without losing its strength or elasticity. As the highest grade of spring wire, it is low in sulfur and phosphorus. Though its tensile strength when hard drawn is 225,000 to 400,000 psi, it is flexible enough to bend 180° without cracking. Additionally, it can wind into a close helix with an inside diameter 1 to 1.5 times the diameter of the wire.

GUIDE WIRE ASSEMBLIES consist of hypodermic tubing and straightened wire. A 36-inch length of 304V (or 304 depending on the diameter) stainless steel straightened wire is selected to fit as closely as possible to the inside diameter of a 30-inch length of 304 stainless steel hypodermic tubing. The stainless steel material of both components make guide wire assemblies effective for applications requiring strength, uniformity and corrosion resistance.

PTFE GUIDE WIRE ASSEMBLIES consist of PTFE light wall tubing and straightened wire. These assemblies are made with a 72-inch length of PTFE light wall tubing and a 72-inch length of 304V (or 304 depending on the wire diameter) stainless steel straightened wire, giving customers plenty of material to make their own specific cuts. The stainless steel material of the wire coupled with the lubricity of the PTFE makes these guide wire assemblies effective for applications requiring precision tolerances and temperature and corrosion resistance.

NITINOL or Nickel titanium is a corrosion resistant, paramagnetic metal alloy of nickel and titanium named for its composition and place of discovery: Naval Ordinance Laboratory. Nitinol alloys possess two unique but closely related properties: shape memory and superelasticity (also known as pseudoeslasticity). Component Supply currently stocks the super elastic alloy, which is kink resistant and flexible. The superelasticity occurs in a narrow temperature range slightly higher than its transformation temperature. Component Supply's offering of Nitinol can be strained up to eight times more than ordinary spring steel without permanent deformation.

PTFE COATED STAINLESS STEEL wire provides dielectric protection and enhances lubricity of stainless steel wire. Component Supply stocks wire in stainless steel 304, which possesses a minimum of 18% chromium and 8% nickel with a maximum of 0.08% carbon. It is in the chromium-nickel austenitic alloy family, and with its low carbon, it is preferable over 302 for applications requiring welding. The coating thickness is between 0.00016" and 0.00039" and is typically green. However, other colors such as gray, blue, black, white and clear are available through special order. This product can withstand heat up to 195°C (390°F) and can be ETO sterilized.

PTFE MONOFILAMENT is used in a wide range of applications requiring precision extrusion, lubricity, high tensile strength, optical clarity, temperature resistance and abrasion resistance. This flouropolymer component effectively serves applications in demanding environments. It is strong, lightweight and flexible tubing with a high dielectric strength over a wide range of frequencies. PTFE (polytetrafluoroethylene) has the lowest coefficient of friction of all polymers making it an ideal choice for applications needing lubricious material. PTFE, also known as Teflon®, is chemically inert, has low extractables and is chemically resistant to acids, bases and all common solvents. This tubing is resistant in the temperature range of 500°F (260°C) to -454°F (-270°C). The melting point is between 635-650°F, the tensile strength is between 2,500-4,000 psi and the specific gravity is between 2.13-2.24.

STAINLESS STEEL STRAIGHTENED WIRE LAB KITS provide a selection of wire in a range of wall thicknesses to labs and shops. Each lab kit offers three pieces of 12-inch long wire in every diameter separated into plastic storage tubes, which are individually labeled with a description and dimensional specifications. These tubes are organized in a high-quality plastic, divided storage box.

Application Examples
MEDICAL: Stainless steel wire is often used in catheter mandrels, stylets, introducers, push pull rods and guide wire assemblies. Guide wire assemblies have various applications in the following areas: coronary, gastroenterology/renal/urology, obstetrics/gynecology, radiology and peripheral vascular. They are used in actuators and push rod assemblies as well. Nitinol also has numerous applications in the medical field including wire mandrels, mechanical switching devices, prosthetics, catheters, superelastic needles, robotic actuators and stents.
INDUSTRIAL: 304 stainless steel, which is spring tempered, is often used to make springs. Music wire is used for compression, extension and torsion, withstands repeated high-stress applications.
LABORATORY: There are many uses for hypodermic tubing in the lab including chromatography tubes with special fittings. Another is needles, both sharp and blunt, for collecting samples or dispensing.

Stock and Customization
Component Supply distributes production quantities of wire products but also offers small quantities for testing purposes. Secondary operations for wire include multiple and compound bend options, cutting to customer-specified lengths, beveling bullnosing, chamfering and various tip options as well as deburring and cleaning.
