0.5ml wall thickness pure nickel seamless precision capillary

Pure nickel pipe is a seamless or welded pipe made from high-purity nickel (Ni≥99.5%) as raw material through vacuum melting, extrusion, cold drawing/cold rolling, heat treatment and precision machining. The core grades are N4 (N02201) and N6 (N02200), corresponding to the American standard UNS N02201/N02200, and complying with standards such as GB/T 2882 and ASTM B161
