Zinc Spooled Wire

Zinc Spooled Wire is a drawn metal filament composed of high-purity zinc or zinc alloys, designed for spooling and precision application. With moderate tensile strength, high elongation (~40%), and good biocorrosion behavior, it excels in biomedical, electronic, and surface finishing applications. This wire exhibits low stress relaxation post-deformation and retains mechanical integrity when tied or bent, a critical trait for surgical thread research. Primary applications include EDM (electrical discharge machining), thermal spraying for corrosion protection, and emerging use in biodegradable surgical sutures. Specific technologies include FEM-modeled fine wire drawing for defect-free surfaces, electrode wire in automated cutting, and alloyed variants for coating pipelines in chloride-rich environments. Zinc’s ability to maintain surface quality post-drawing while offering a tunable corrosion profile makes it an ideal choice in advanced manufacturing, especially where biodegradability or precise erosion is desired.
