I recently needed some specialist wire (0.1 mm enamelled copper, with self-bonding coating), and came across The Scientific Wire Company. Very helpful, fast, and happy to do small orders. They do a huge range of stuff, some of which will be of interest to model engineers (e.g, stainless steel wire, silver wire, gold wire, tungsten wire, nichrome wire, flexible wire with high temperature silicone coating, woven meshes and much more).
My order, which was a special, took just 2 days from the time I phoned.
Address is 1 Raven Road London E18 1HW. Phone 020 8505 0002
