Drawn Wire Manufacturers

Drawn wire is created by pulling metal through a die to reduce its diameter and improve surface finish. At California Fine Wire Company, we specialize in precision cold drawn wire manufacturing using a wide range of materials, including stainless steel, copper, nickel alloys, precious metals, and refractory materials. All of our wire is cold drawn at room temperature to preserve material strength and deliver exceptional dimensional accuracy. Our cold drawn l wire is available in diameters ranging from 0.0003″ to 0.040″, with tolerances as tight as ±0.000025″. Formats include round, ribbon, bifilar, and stranded configurations.

To meet specific application requirements, we provide a range of finishing options such as strand and batch annealing, electroplating, and enamel or PTFE coatings. CFW Co. offers a wide range of wire packing solutions to meet your specific application needs. Options include standard spools, bonding spools, cut-to-length pieces, and cleanroom-compatible blister packaging.

Dimensional inspections reach down to ±0.00005″. Electrical and mechanical testing is available to meet industry-specific requirements. California Fine Wire is ISO 9001 certified and complies with DFARS, RoHS, REACH, and ITAR.

California Fine Wire supplies cold drawn for a variety of specialized uses. Our products are known for precision and consistency, making them a strong choice for applications requiring tight tolerances and reliable performance.

• Medical: Used in catheters, implantable devices, and sensor leads where fine diameters and clean finishes are essential.
• Aerospace: Supports avionics, satellite systems, and guidance equipment that require lightweight, high-strength materials.
• Electronics: Common in semiconductors, bonding wire, and fine electrical connections in compact assemblies.
• Defense: Applied in communication systems, surveillance devices, and mission-critical electronics that demand consistent performance under extreme conditions.
• Instrumentation: Used in thermocouples, RTDs, and other precision measurement devices for lab and industrial settings.

Our wire is produced with application-specific needs in mind, helping manufacturers meet strict quality and performance targets.
