Methods of Manufacture
Continuous Cast Process
Continuous casting is a process in which
solidifying metal is extracted through an open
ended mold fitted with a cooling unit. Heat is
extracted and the metal exits the mold as a solid
with a constant cross section. It allows lower
cost production of metal sections with better
quality, due to finer control through automation
of the casting process. Generally a saw is set
up after the withdrawal rolls, in order to cut the
casting at constant lengths. The castings are
semi-finished products.

Centrifugally Cast Process
Centrifugal casting is done by pouring molten
metal into a rotating mold. The centrifugal force
acting on the mold helps in feeding and positioning
the metal in the mold. Mold rotation is continued
until after the metal is solidified. Centrifugal casting
results in denser and cleaner metal as heavier
metal is thrown to parts of the mold away from the
center of rotation and the lighter impurities like
slag, oxides and inclusion are squeezed out to the
center. The castings produced have a close grain
structure, good detail, high density and superior
mechanical properties.

Wrought Alloys
Extrusion is the process by which long straight
metal parts can be produced. The cross-sections
that can be produced vary from solid round,
rectangular, to L shapes,Tshapes,Tubes and
many other different types. Extrusion is done by
squeezing metal in a closed cavity through a tool,
known as a die using either a mechanical or
hydraulic press. There are two main types of
Extrusions: Hot Extrusions and Cold Drawn. The
forging process involves working metal parts above
their recrystallization temperature and gradually
shaping them into the desired configuration through
the hammering or pressing of the work piece.

Sintered Bronze Process
Sintered Bronze Process
The process of powder metallurgy has
three basic steps:
1. First, the metal, in this case, bronze or bronze
alloy, is made into a powdered form. This can
be achieved by a number of methods
including grinding, chemical decomposition
and the most common atomization.
2. The metallic powder is then poured into a die
or mold cavity and compacted under great
pressure in order to adhere the particles.
This occurs at room temperature.
3. The metal part is then inserted into a furnace
where the extreme heat fuses the metal
particles together to form a rigid, high strength
and porous component. This part of the
process is called sintering.

Bronze Products
Wrought Products
Brass/ Bronze Plate – Widely used in
industrial, architectural, and marine applications.
Brass sheet is commonly used for door
hardware, tooling, furniture, nuts, gears and
small hardware. Moreover, its variation in alloy
offers a strong, wear resistant and highly
weldable ability.
• C46400 Naval Brass/ Bronze Plate
• C46400 Diamond Cut Naval Brass

Ground Plate
Ground Plate
Ground Plate is Atlas Bronze's specialty product.
This material is a cost saver and time saver. Since
the material is stocked in a ground condition +/- .002
on the thickness (we aim for +/- .000 so if you need a
closer tolerance we will mic material upon request)
Our bronze flat stock is machined from continuous
cast, fine grain plate. Our bars are supplied ground
top & bottom.
Benefits: No milling or grinding necessary on the top
or on the bottom – already done for you!! No need to
block it in, taping it down or toe clamp it anymore!
Sizes: C95400 Aluminum Bronze & C93200 Bearing
Bronze from ¼ to 1” x 12” wide x 144” cut to your size.
Inquire within for larger sizes.
