The Flat Magnet Wire program has been expanded to sizes that range from 30 to 9 AWG (0.25 to 3.0 mm) in five thickness-to-width ratios: 1:2, 1:2.5, 1:3, 1:3.5, and 1:4. All sizes are available on two spool sizes: 10-lb spools (6.0 in. O.D. by 4.0 in. high) or 20-lb spools (6.0 in. O.D. by 8.0 in. high). Wire gauges of 20 AWG and heavier are also supplied on 80-lb spools (12.0 in. O.D. by 8.0 in. high). There are two types of insulation: polyester/polyamideimide (heavy, UL recognized, Class 220 as round wire and also in Class 200 as round wire) and polyester/polyamideimide/bondcoat (heavy, UL recognized, Class 180 as round wire). The cost of 18-AWG wire in 250-lb quantities is $5.50/lb, including the current copper adder of $1.06/lb.
