Solders for Medical Technology – Precision and Biocompatibility in Every Joint
LOT-TEK supplies approved alloys and wire products for implants, catheters and surgical equipment
The field of medical technology demands the highest levels of quality, biocompatibility, and reliability. At LOT-TEK, we offer specially developed solders and joining materials designed for critical medical applications – from pacemakers and catheters to stents and surgical instruments.
Materials such as platinum, gold, platinum-iridium (Pt/Ir) and palladium-iridium (Pd/Ir) are commonly used due to their excellent resistance to corrosion, electrical conductivity, and long-term stability. Depending on the application, additional metals such as rhenium, tungsten, or ruthenium are also employed.
For stent fabrication, extremely fine wires are needed to construct flexible, biocompatible lattice structures. At LOT-TEK, we supply high-precision medical wires in defined diameters and tolerances. When it comes to catheters, ultra-thin platinum marker sleeves are used to ensure radiopacity during diagnostics or surgical interventions – requiring burr-free surfaces and consistent dimensions.
In pacemaker manufacturing, platinum pins must be securely joined using gold solders to create hermetically sealed electrical feedthroughs. These soldered joints are essential for the safety and longevity of active implants and must meet strict regulatory and technical requirements.
