Brass exhibits about 28% the conductivity of copper.

But note that low silicon bronze (the material in question) has 12% of the
conductivity of copper. High silicon bronze (2.8 - 3.8% Si) is only 7%.

Red brass is 37%. "High conductivity bronze," also known as "penny bronze,"
is 41%.

Conductivity of copper alloys ranges all over the map. You really have to
check the conductivity of the particular alloy to know what it is.
