Constantan Wire, 25 Gauge
For Hot Wire Cutting, Resistance Elements, Thermocouples. High-resistance alloy of approximately 40% nickel and 60% copper with a very low coefficient of thermal expansion (measure of expansion on heating). It is used in electrical resistors and other electrical applications because of its constant resistance under variations of temperature.

40 gauge 304V Stainless Steel Ribbon
by Fort Wayne Metals |
 |
This wire is actually a ribbon made of 304 stainless steel. It works
perfect for bridgewire applications and is actually easier to solder
than nichrome. This alloy is the most popular for medical appliances.
The ease of joining with solder or welding, combined with excellent
strength makes it desirable. This alloy is also one of the least expensive
medical materials. Some examples of end products are stylets, catheters,
guide wires, springs and needles.

Aerocon HotHead Electric
Match Heads
These small printed circuit board chips have a 50 gauge nichrome
bridge wire wrapped and soldered to the tip. The hard work has been
done for you! This will give a resistance similar to a Daveyfire or
Oxral electric match. No LEUP required!
50 pieces - $10.00
Easy to Make Matches:
Cut your shooter's wire to desired length.
Solder wire to both sides of the HotHead.
Dip HotHead into a pyrogen
Presto, an electric match for pennies.
38 gauge wire HotHeads available by special order, requires more current
for firing.

About Manganin®
From Wikipedia: Resistance alloy with moderate resistivity and low temperature coefficent. The resistance/temperature curve is not as flat as the constantans nor are the corrosion resistance properties as good. Manganin is a trademarked name for an alloy of copper, manganese, and nickel. Typically, the alloy contains 12% manganese and 2% nickel, with 86% copper. It was first developed by Edward Weston. Manganin foil and wire is used in the manufacture of resistors because of its superior temperature coefficient and long term stability. Several Manganin resistors served as the legal standard for the ohm in the United States from 1901 to 1990. Manganin is also used in gauges for studies of high-pressure shock waves (such as those generated from the detonation of explosives) because it has low strain sensitivity but high hydrostatic pressure sensitivity.
