Our medical fine wire is produced from high-quality materials such as platinum, titanium, stainless steel, and gold alloys, ensuring performance and consistency in critical, life-saving applications. In addition to our standard offerings, we provide custom, made-to-order solutions tailored to unique specifications and specialized requirements.
With over 60 years of wire manufacturing experience, our team delivers reliable, precision-engineered solutions backed by exhaustive documentation and full material traceability.
Research and Prototyping
For research-driven applications, having a partner that can adapt to evolving requirements is essential. At California Fine Wire Company, we specialize in scalable ultra fine wire solutions, supplying both small and large quantities to bridge the gap between concept, prototyping, and commercialization. This enables engineers, researchers, and product developers to access high-performance materials without the constraints of high-volume production or cost barriers typical of mass-market manufacturers.
We work closely with customers during early-stage development, offering a wide range of capabilities, including PTFE coated wire, bonding wire, and custom alloy configurations. This flexibility supports everything from feasibility studies to iterative prototyping and scale-up.
Since 1961, we have built a reputation for precision, consistency, and technical expertise. Our team understands how to translate requirements into reliable, real-world solutions, supported by rigorous documentation and full material traceability. Every product reflects decades of experience supporting demanding, research-driven applications.
Temperature Measurement TC Wire
Many applications requiring ultra fine wire depend on precise temperature measurement using thermocouple (TC) and Resistance Temperature Detector (RTD) materials. These technologies are widely used across industries such as aerospace, medical, and automotive, where accuracy and reliability are critical.
RTDs are among the most accurate temperature-sensing devices available. Unlike thermocouples, which rely on two dissimilar metals, RTDs typically use a single pure element with a well-characterized and predictable resistance-to-temperature relationship.
California Fine Wire Company manufactures high-precision wire for temperature sensing applications, including DIN grade platinum, pure TC platinum, high and low TCR nickel, and high-purity copper. We offer a wide range of wire diameters and tolerances to support both standard and custom requirements. With decades of experience producing precision wire, we support customers with consistent, reliable materials backed by full documentation and traceability for critical temperature measurement applications.
Semiconductor Bonding Wire
Bonding wire plays a critical role in semiconductor devices, creating the electrical connections within integrated circuits that enable signal transmission. As devices continue to shrink and performance demands increase, consistency and reliability at this scale become essential.
At California Fine Wire Company, we manufacture high-purity bonding wire using gold and aluminum materials designed for semiconductor applications. We offer a range of wire diameters, spool configurations, and custom solutions to match specific customer requirements.
With decades of experience in precision wire manufacturing, we understand what it takes to produce consistent, reliable material for demanding environments. Our bonding wire is produced with careful control and backed by thorough documentation and full material traceability, giving our customers confidence in both development and production.
Resistance Wire
Resistance wire is used in a wide range of applications, from medical devices such as cochlear implants to aerospace instrumentation and research environments. Designed with controlled electrical resistance, resistance wire is commonly used in heating elements, resistors, and other precision electronic components where performance must remain consistent.
At California Fine Wire Company, we manufacture resistance wire using materials such as nickel-chromium (NiCr), nickel and nickel alloys, copper, platinum, and platinum alloys. We offer a range of wire diameters and configurations to support both standard and custom application requirements. Our products are backed by thorough documentation and full material traceability, ensuring reliability in demanding applications.
Precious Metals Fine Wire
Precious metal wire is used in high-performance applications where conductivity, corrosion resistance, and reliability are critical. Materials such as gold, silver, platinum, and platinum alloys are commonly used in electronics, medical devices, and bonding wire applications.
At California Fine Wire Company, we manufacture precision fine wire from a range of precious metals with controlled purity levels to meet demanding specifications. Our robust supply chain allows us to source and process high-quality materials consistently, supporting both standard and custom requirements.
