Federalloy
is Foundry Friendly
Experience with foundrymen since 1993 who have
used a whole variety of Federalloy brass alloys makes it possible
for us to conclude the following:
|
- The desired pouring temperature for heavy or light castings
as is the case with leaded brasses is crucial. However, some
of the Federalloy alloys have a higher melting point (liquidus)
than the leaded brasses they are replacing. Consequently, an
adjustment must be made reflecting the higher pouring temperature
without fear of burning into sand, shrinkage porosity, gas holes
or other defects associated with hot metal.
- Federalloy's "no burn-in" feature enables Federalloy castings
to have more definition which results in crisper markings and
more legible identification numbers.
- The appearance of Federalloy rough castings is noticeably
preferable to leaded brass due to superior microstructural characteristics.
- Federalloy alloys' improved surface finish requires less shot
blast, thereby reducing cleaning costs and shortening cycle
times.
- The uniform distribution of bismuth makes Federalloy alloys
easier to polish and buff.
- Also, due to the uniform distribution of bismuth in Federalloy
alloys, as opposed to the non uniformity of lead in leaded brass
castings, a better surface condition is achieved which may reduce
machining requirements and therefore, machining costs.
- Federalloy alloys will demonstrate a higher luster when plated.
