Hi there,
Do you guys happen to know what’s the difference between brass,
bronze, and white bronze castings? When do you guys use which
material?
Thank you
Best,

The brass is going to be a zinc alloy ranging from reddish to more
yellow. It will tend to be more malleable but not as strong as the
Bronze. It can be touchy to cast, and you need fume control due to
the zinc fumes.
Classic bronze is strong and dense, but can be brittle. The color is
more of that classic rich “bronze” color. It’s (classically) a
copper/tin alloy; but there are a few zinc, silicon, or phosphor
bearing alloys that are also being called “bronze”.
White “Bronze” is a nickle bearing alloy. It’s not as dense as the
other two, and is usually more brittle than the other two.
I don’t generally like the white bronze alloy, and if I need a
non-precious white metal, I’ll go with nickle-silver.

Alloy content. All are coper based but the alloying metals change
things like color, hardness, workability, weldability,
weatherability, etc. I mostly use Everdur, a copper and silica alloy
mostly used in the marine industry for weatherability. Casts ok but
not great but welds with NO color change. Herculoy is more liquidous,
so easeir to get finer detail castings but metal color changes when
welded as one alloy component, zinc, burns out. Just do a search for
bronze allous and brass alloys and you will see what is in them and
their properties. There are copper alloys in the jewelry industry
that are alloyed to closely mimic gold in color. Hope this helps.
