Ultra-fine wire, unmatched consistency
At Alleima, fine wire drawing is more than a process—it is the foundation of our ultra-fine medical wire and advanced wire-based components. Decades of metallurgical expertise and continuous innovation drive our ability to deliver ultra-fine wire with exceptional precision and consistency for critical applications in medical devices, electronics, thermoelectric systems, and electromechanical components.
Our drawn wire is more than a material — it’s a solution. Whether for a life-saving implant or a precision sensor, our custom wire products are engineered to meet the tightest tolerances, cleanest finishes, and most demanding application requirements.With Alleima, you move forward with confidence—supported by technical excellence and a commitment to advancing your possibilities.
Our expertise
Precision drawing across alloys and geometries
Alleima delivers fine wire solutions in round, flat, ribbon, and rectangular geometries, with round wire diameters from 0.010 mm to 10 mm and ribbon wire thicknesses from 0.013 mm to 0.75 mm. Aspect ratios up to 10:1 or higher are achievable. With more than 200 standard alloys and custom compositions, we provide the precise mechanical and physical properties required for your application.
Surface quality and tolerances you can trust
Surface integrity begins with our in-house diamond die production. Crafted by expert hands, these dies enable us to achieve ultra-smooth finishes and tight dimensional control. Our processes are engineered to meet or exceed ASTM, NEMA, and customer-specific standards. We offer a range of coatings, finishes, and heat treatments to optimize performance and integration.
Complete supply chain control and flexibility
Alleima maintains full control of the value chain—from alloy melting to final wire drawing. This ensures rapid response times, consistent quality, and flexible delivery. We offer a variety of delivery forms, including spools, coils, braider bobbins, and straightened lengths, all tailored to your requirements.
