What sets us apart is our use of high-quality oxygen-free copper alloys and consistent welding products that customers can rely on to keep their production going. Superior Welding Performance With decades of expertise, Luvata is known for producing copper alloy adapters and shanks in any shape or size. Whether the need is for a straight adapter or a bent shank to reach difficult areas of a vehicle, we have the solution available. Our products are designed to fit your exact requirements and can be assembled directly into welding guns. We also offer the compatible welding caps for flawless welding performance. We offer the following alloys: Kova®: Copper, Nickel, Silicon and Chromium (CuNiSiCr) Z-Trode®: Copper Zirconium (CuZr) A-Trode®: Copper Chrome Zirconium (CuCrZr) Copper Nickel Silicon (CuNiSi) Nitrode® and Cupal®: Dispersion Strengthened Copper (DSC) New Solution for Longer-Lasting Adapters In addition to traditional adapters, we offer patented intermediate threaded adapters. These smaller adapters screw onto the end of the shank and can last up to three times longer than regular ones. The intermediate connector saves time and money by reducing the frequency of shank replacements.

Our technical support for Luvata welding products is highly regarded, and we have assisted numerous customers in enhancing their production processes with Luvata products. Kova®: the Berylliym-Free Alloy Luvata’s own alloy Kova® is a ‘beryllium-free’ alloy made of copper, nickel, silicon and chromium (CuNiSiCr). Kova® is a high-strength, beryllium-free precipitation hardening alloy with medium-high electrical and thermal conductivity. It is the perfect replacement for harmful beryllium copper alloys. Benefits: Easy to machine Extended use due to hardness High strength with moderate thermal and electrical conductivity Easy disposal Applications: Adaptors Shanks Projection welding electrodes Weld wheels Technical Information AlloyKova® NK203 is a RWMA Class III alloyChemical compositionNi 1.8 – 3.0%; Si 0.4 – 0.8%; Cr 0.1 – 0.8%; Fe 0.15% max;.
