42 Swg Tinned Copper Wire

42 SWG (Standard Wire Gauge) tinned copper wire is an ultra-fine electrical conductor with a nominal diameter of 0.1016 mm (approximately 0.004 inches). It consists of a high-purity copper core coated with a thin layer of tin, which protects against corrosion and oxidation while significantly improving solderability.Key Specifications Diameter: 0.1016 mm (approx. 0.1 mm). Material: High-quality EC grade copper (typically 99.8% to 99.95% purity). Surface Treatment: Tinned (hot-dip or electro-tinned) for a glossy, silver-coloured finish. Density: Approximately Applications and Usage Electronics & Telecommunications: Ideal for intricate circuit repairs, jumper wires, and fine-gauge connections. Small Motor Windings: Used in the manufacturing of miniature solenoids, inductors, and small transformer coils. Harsh Environments: The tinned coating makes it suitable for applications exposed to moisture or high temperatures where bare copper would quickly oxidise. Fuses: Sometimes employed as a precise tinned copper fuse wire.
