Brass is only 28% as conductive as copper. Some bronzes are as low as 7% as conductive as copper! Copper is the standard by which electrical materials are rated and conductivity ratings are expressed as a relative measurement to copper. These ratings will frequently be expressed as "28 IACS".
A list of the conductivity of metals sorted by resistivity from silver to graphite.
Conductivity of Phosphor Bronze. The most widely used phosphor bronze contains 0.2% phosphorous and 5% tin; It has only half the conductivity of its most popular brass cousin, copper-30% zinc (15% IACS vs. 28% IACS).
Copper, Brass and Bronze, otherwise known as the “Red Metals”, may look the same initially but are actually quite different. Copper. Copper is used in a wide range of products due to its excellent electrical and thermal conductivity, good strength, good formability and resistance to corrosion.

Copper is a non-precious, red-gold colored metal with high electrical conductivity. In fact, the conductivity of copper is so high that it is considered the standard by which other non-precious metals and alloys are compared. The conductivity of copper is affected by the addition of other metals to make alloys.
Conductivity of Brass. This family of alloys, which consists of copper and zinc, demonstrates that the conductivity of pure copper is often not required for connectors. More contacts, terminals, switches, etc. are stamped and formed from copper-30% zinc than from any other copper alloy. Yet its conductivity is only 28% that of pure copper.
The two metals are close on the scale of conductivity, with copper having the more desirable characteristic. The conductivity of copper is about 0.6 megamho/cm while that of aluminum is about 0.4 megamho/cm.
