As a fine wire manufacturer, Luma Wire Tech plays a vital role in the medical device industry. Our gold-plated tungsten wires are widely used in stents, guide wires, catheters, and surgical instruments. Thanks to tungsten’s high density, the wires are visible under X-ray, enabling surgeons to navigate with precision during minimally invasive procedures. The gold plating protects against corrosion and ensures biocompatibility for temporary use inside the human body. Beyond cardiovascular devices, our wires are used in neurosurgical needles, deep brain stimulation research, and diagnostic detectors. For medical OEMs and researchers alike, we provide fine wire solutions that meet the strictest regulatory standards
In the aerospace and space industries, every gram and every micron counts. Luma Wire Tech is a trusted fine wire manufacturer for companies building satellites, spacecraft, and advanced avionics. Our gold-plated molybdenum wires are the material of choice for self-deployable reflector antennas, combining lightweight properties with thermal stability and RF conductivity. During launch, our wires withstand vibration and mechanical stress, while in orbit they resist radiation and extreme temperature fluctuations. In aerospace, our wires support sensors, actuators, RF modules, and avionics systems, ensuring reliable performance where failure is not an option.
As a fine wire manufacturer serving the electronics industry, we deliver wires that enable miniaturization and high performance in semiconductors, microchips, and advanced electronics. Our tungsten and molybdenum fine wires are used in bonding, wafer probing, probe needles, and interconnects. Gold plating ensures stable conductivity, corrosion resistance, and reliable soldering—critical for integrated circuits and next-generation 5G and RF systems. Fine wires from Luma are also used in supercapacitors, batteries, and quantum computing research, where extreme accuracy and material stability drive innovation.
The future of textiles is functional, and as a fine wire manufacturer, we enable the integration of gold-plated tungsten and molybdenum wires into fabrics. These smart textiles combine strength, flexibility, and conductivity, creating new possibilities for wearables, protective gear, and industrial fabrics. Applications include medical garments with integrated sensors, protective suits with EMI shielding, and sportswear with biometric monitoring. In aerospace and defense, woven fine wire textiles deliver both protection and connectivity. By providing fine wires for e-textiles and technical fabrics, we support the growing demand for IoT-enabled materials and multifunctional textile systems
For over nine decades, Luma Wire Tech has supported innovation by combining advanced coating technology with micron-level manufacturing expertise. Whether you need ultra-thin wires for medical implants, aerospace systems, or next-generation electronics, we deliver fine wire solutions that perform where failure is not an option.
