Is there any special wires for low resistance (1m ohm) for 1A DC.
 

hello

Yes , Shunt for Current measuremnt use
manganin, un alliage spécial de manganèse, cuivre et nickel..
Click to expand...

If you use Copper only..you will have to correct the value f(Temperature)...
depend of what accuracy you need..

example: length= 88 mm copper wire 1,5mm² => 1.009 mOhm at 20°C (1,088 at 40°C)

You can use also "Laiton" wich Temperature coefficient is 3 times better than Coopper
