Product Overview
Nickel wire is a thin metal filament primarily composed of nickel, produced through rolling and drawing processes. Common forms include solid round wire or clad wire. Depending on purity and alloy composition, it can be categorized into various types such as pure nickel wire, nickel-chromium alloy wire, and nickel-iron soft magnetic alloy wire.

Key Advantages
Corrosion Resistance: Forms a dense passive film in media such as strong alkalis, acids, and seawater, offering corrosion resistance second only to silver among common metals.
High-Temperature Performance: Maintains good strength at temperatures above 600 °C, suitable for high-temperature applications like heating elements and vacuum lamp filaments.
Good Electrical Conductivity: Low resistivity and stable resistance-temperature coefficient, ideal for precision resistor wires and temperature compensation components.
Excellent Workability: Can be cold-drawn to fine diameters like 0.025 mm, offers high bend cycle count, high surface finish, and ease of welding.
Tunable Magnetic Properties: Alloying (e.g., Ni-Cr, Ni-Fe) enables high electrical resistance or soft magnetic characteristics to meet various functional needs.
