Does anyone know where I can buy small quantities of Manganin wire or
sheet for making homebrew current shuts ?

In the past I've use 304 stainless steel but Manganin is  better.

            304 SS        Manganin    Copper
---------------------------------------------------------------
Resistivity (uohm-cm)    72        48        1.7
Temp. coeff (ppm/K)     1040        +-15        4040


Where temperature coefficient is alpha in following the following
equation. R = Rref * (1 + alpha*(T - Tref))
