BRASS AND BRONZE CASTINGS
Many foundries only run a handful of common alloys. At Warner Bros. Foundry Company our reputation is on running a wide range of aluminum and copper based alloys. If you don’t see any alloy of interest, listed below, please let us know. We are happy to quote other alloys.
Only the highest quality Certified Ingot is used for the production of our Brass and Bronze casting, continue reading to learn about the properties of these alloys.
