NEW PRODUCT RELEASE - Bromalloy® Castings
Franklin Bronze & Alloy Company is an established
manufacturer of high-quality nickel-boron alloy and Bromalloy glass mold accessory
castings. Parts manufactured include guide rings, baffles, plungers,
inserts, thimbles, blowheads, and top-plates, and all parts are
investment-cast to shape and size from customer drawings. Parts
are then finished in-house or shipped to the customer in as-cast
condition for machine finishing.
Tooling
All tooling required for glass mold casting is made
in-house, allowing quick delivery and substantial customer savings.
In addition, Franklin Bronze has immediate access to efficient,
competitive air freight service, allowing us to economically deliver
our product throughout the world.
Bromalloy Castings
Franklin Bronze now offers all these same castings in Bromalloy.
Bromalloy is a new stainless steel alloy that has been developed
specifically to replace the higher cost nickel based alloys.
In addition to significant savings in purchasing the castings, parts
made in Bromalloy are actually out performing the nickel based
castings when put in service. Bromalloy castings are 100%
corrosion resistant and are readily repairable when worn out.
Bromalloy castings are shipped from Franklin Bronze in the annealled
condition at a hardness of 36-40 Rc ready to be machined. See
below for information on this product.

Nickel-Boron Alloy Castings
Franklin Bronze has been a manufacturer of Nickel-Boron Alloy
Castings for over 20 years. These alloys have been well proven
and accepted in the glass industry for use in accessory castings.

The Advantages of Nickel-Boron
The advantages of nickel-boron alloy castings over traditional machined
and hard-faced cast iron parts are significant to both mold manufacturers
and glass container factories.
Container Mold Shop Advantages
• A one-step machining process to finished part
allows a much quicker throughput
• Vent, blow holes, and other details are cast and
require no machining
• All welding operations are eliminated
• Less chance of defects which cause part rejection
at end of process
Other Advantages Realized in Glass Production
• Improved part life
• Improved wear resistance
on parts' non-glass contact surfaces
• Improved thermal operating
conditions
• Nickel part can be repaired
six to eight times
• Worn-out or discarded
parts can be sold for valuable scrap nickel
