Alcatel Magnet Wire Inc. has
combined established abilities in
magnet wire engineering and
production with large scale
manufacturing facilities to provide a
source of outstanding copper and
aluminum magnet wires.
The data presented in this booklet is
consistent with NEMA MW 1000
specifications and is applicable for all
film and insulation types. The data is
given to help in the application and
design choices of copper and
aluminum magnet wire.
All information contained herein is
believed to be reliable and accurate.
Note that it may not be all inclusive
nor entirely suitable to all local codes
and practices; and therefore they
should first be confirmed by the user.
The information found is this guide is
given and accepted at the user’s risk
and Alcatel Magnet Wire Inc. assumes
no responsibility for results obtained or
damage inherent from use of the
information in whole or in part.
It should also be noted that metric
units, given in this catalogue, are
approximate equivalents to those of
the English system of measures, and
thus are given as information only.

AWG SIZE
* These diameters are rounded numbers calculated from the inch value.
** The nominal areas of AWG wires have been calculated in square inches and then converted to square millimeters.
† The differences in diameter and area have been calculated from values more precise than those shown in the table.

Resistance Variation with Temperature
The resistance of a conductor varies
with temperature as follows:
Rt = Rt1 (1+αt 1(t-t1))
where:
Rt is the resistance at any
temperature t, Rt1 is the known
resistance at the stated temperature t1.
αt 1 is the temperature coefficient of
resistance at the stated temperature.
Because it is most practical to measure
resistance at room temperature, it is
convenient to choose 20°C as the
stated temperature t1. The formula thus
becomes:
Rt = R20 (1+α20 (t - 20))
The temperature coefficient of
resistance varies with conductivity n,
as well as temperature.
α t1
=
1
(1/na) + (t1 - 20)
Where a is the temperature coefficient
of resistance for the given conductivity,
n, at 20°C.
n
Conductor
a
(I.A.C.S)
Copper
0.00393
100%
Aluminum
0.00660
61.8%
Thus the resistance formula for copper
becomes:
Rt = R20 (1+.00393 (t - 20)
= 234.5 + t × R20
254.5
For aluminum
Rt = R20 (1+.00408 (t - 20)
= 245.1 + t × R20
245.1
Thus conversion of resistances at
operating temperatures to resistance at
20°C is achieved by multiplying by the
inverses of the factors.
That is:
R20 =
254
234.5 + t
R20 =
x Rt for CU
1
245.1 x Rt for AL
1
225.1 + t
These factors for converting resistance
to 20°C are listed from 0 to 250°C in
the following tables on the next two
pages.
For a temperature of 20°C the
coefficient becomes:
α 20 = .00393 for Copper
= .00408 for Aluminum

Variations in Conductor Resistance Due to Diameter Tolerance
The resistance of a given length of
wire is inversely proportional to its
cross-sectional area, and thus for
round wire the square of its diameter:

where: D is the diameter in inches
d is the diameter in millimeters
A is the cross-sectional area in square inches
a is the cross-sectional area in square millimeters
It is easily seen that the resistance will
reach its maximum when the wire
approaches its minimum diameter.
The wire diameter corresponding to
any resistance measurement is given
by the following formulae:

Wire and Cable Metric Calculations
Dimensions
Mass
Force or Tension
Length
mils x 0.0254 = mm (millimetres)
inches x 25.4 = mm
feet x 0.3048 = m (metres)
miles x 1.609344 = km (kilometres)
pounds x 0.45359 = kg (kilograms)
tons (2000 lb) x 0.907185 = t
(metric tonnes)
pounds (force) x 4.448 = N
(newtons)
mass (in kg) x 9.8066 = N
(weight at or near sea level)
Mass per unit length
lb/1000 ft. x 1.48816 = kg/km
(kilograms per kilometre)
lb/mi x 0.28185 = kg/km
Area
circular mils x 0.0005067 = mm2
(square millimetres)
sq. in x 645.16 = mm2
sq. ft. x 0.092903 = m2
(square metres)
sq. yd. x 0.836127 = m2
sq. mi. x 2.58999 = km2
(square kilometres)
Solid wire weight
mm2 x 8.89 = kg/km (for copper)
mm2 x 2.70 = kg/km (for aluminum)
mm2 x 7.83 = kg/km (for steel)
Temperature Conversion
Volume
cu. in. x 16.387 = cm3
(cubic centimetres)
cu. ft. x 0.028317 = m3
(cubic metres)
gallons x 4.54609 = L (litres)
U.S. gal. x 3.7854 = L (litres)
°F to °C: °C = (°F minus 32) x 5/9
°C to °F: °F = (°C x 9/5) plus 32
Force per unit area
(stress, pressure, tensile strength, etc.)
lbf/in2 = (psi) x 6.895 = kPa
(kilopascals)
lbf/in2 x 0.006895 = MPa
(megapascals)
N/mm2 = MPa
Note
Kilopascals are used generally for fluid
pressures. Megapascals are used
generally for stresses in materials, i.e.
for tensile stress, modulus of elasticity,
etc.SI Prefixes
