WIRES: Copper, Constantan, Nichrome, Insulated, Uninsulated

A variety of copper, constantan and nichrome wires both Insulated-Uninsulated, 50g-125g-250g, tinned: 20M-25M for use in the science laboratory.

(Wikipedia excerpt: "...A wire [W] is a flexible, round bar of metal. [W] are commonly formed by drawing the metal through a hole in a die or draw plate. [W] gauges come in various standard sizes, as expressed in terms of a gauge number or cross-sectional area. [W] are used to bear mechanical loads, often in the form of [W] rope. In electricity and telecommunications signals, [W] can refer to electrical cable, which can contain a solid core of a single [W] or separate strands in stranded or braided forms.

Usually cylindrical in geometry, [W] can also be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-wound coil springs, such as the Slinky toy, are made of special flattened [W] ....")
