The following sizes are too large to wind onto
wire cards.
They are shipped as free coils taped together.
These sizes don't have nearly as much tendency
to get tangled as the small sizes do.
|
The
following are on plastic spools and are shipped in a small Priority
Mail box. $5.50 postage is charged for orders from this section
and covers from one to 16 spools of 1/8 lb or 1 to 8 spools of 1/4 lb
for the same $5.50. Note: this is for USA only. Please
contact for international
shipments. |
Click on this button (only once) to add the
$5.50 shipping for order with spools (items below).
Failing to add this will delay your order while we contact you
to tell you that you need to add the $5.50 shipping. The
shipping is not added automatically. |

There is a huge difference between 40
gauge wire and 14 gauge. The larger the gauge number, the
smaller the wire diameter. 40 gauge is hair fine. 14 gauge
is about the size of a wire coat hanger and very stiff. The
difference between 40 gauge and 38 gauge is very little. The
difference between 14 gauge and 16 gauge is significant. The
smaller the wire size, the less difference between similar gauges and
the larger the gauge, the more difference between similar gauges
Small diameters, typically 34 gauge to
40 gauge are used for igniters because a low voltage and current will
cause a short piece of these sizes to get so hot they will vaporize
and in the process ignite a pyrogen which will ignite a model rocket
motor or an ejection charge. It is also used to ignite other
things such as smoke or flash powder in magic acts.
Heater elements use a variety of gauges
but will often be in the range of 26 to 32 gauge. Electric
heater or heating elements are coiled. Coiling will increase the
temperature over straight lengths of the same size and length due to
the heating affect of neighboring coils.
26 gauge is probably the most common
size used for foam cutting but may range from 22 to 28 gauge.
The heat generated depends on the length of the wire and the voltage.
18 gauge is a common size nichrome wire
used for heat sealing poly bags. Flat nichrome ribbon is also
often used (we don't carry the ribbon...yet).
The largest size, 14 gauge to 18 gauge
is normally used in kilns for firing ceramics because of its high heat
resistance. It can be used to hold up pieces sitting on the
bottom of the kiln or used to suspend items while firing. 14
gauge copper wire is the most common size of house wiring in Romex
wire.
You might see gauge also spelled gage.
Either are correct. AWG is also used in place of gauge when
specifying size so you might see 14 AWG rather than 14 gauge or 14
gage. AWG stands for American Wire Gauge and is the
standard for non ferrous wire sizes.
