UABRONZE LLC is the manufacturer of rolled products and billets of copper-based alloys (bronze and brass) mainly for machine building industry and for companies that repair the equipment.
We carry out the following types of casting:
-
centrifugal casting (pipes, bushings, crowns, liners and other rotating objects with internal bore)
-
gravity sand casting (plates, linings, housings and other shaped parts)
-
gravity casting in coke (bars and simple shaped parts)
The employees of our company have many years of experience, thanks to which we manufacture high quality products.

CENTRIFUGAL CASTING
Centrifugal casting is a method to produce castings that have the shape of rotating object, such as pipe, bushing, ring, worm gear, liner, motor-axle bearing, etc.
The molten metal is poured into a rotating mold during centrifugal casting, where it is pressed against the mold wall by centrifugal forces, cooled, and crystallized. This produces a hollow casting with high quality properties, without porosity, sinks and other defects.
There are two ways to cast the parts at the facilities of UABRONZE LLC:
-
With a vertical axis of rotation. This method is used to cast short parts: crowns, gears, washers, bushings.
-
With a horizontal axis of rotation. This method is used to cast long parts: pipe billets, bushings, liners.
We have the technical ability for centrifugal casting of parts with diameter of up to 550 mm and length of up to 500 mm, with total casting weight of up to 400 kg.

GRAVITY SAND CASTING
Sand casting is used to produce castings that are impossible or difficult to produce by centrifugal casting. These are such parts as plates, linings, housings and other shaped parts. In this casting method, a model (a copy of the part) is first made of wood or polystyrene, which is molded with a sand mixture. After releasing the model, the voids are created and filled with liquid metal through a sprue system. After approval, the casting is released, the sprues and profits are cut off, cleaned, and delivered to the machining section.
SPRUE CASTING
A sprue is a collapsible steel or cast iron mold into which liquid metal is poured and where it takes on the required geometry of the casting.
This method is used at UABRONZE LLC to make castings of simple configuration, such as rods, bars, circles and shaped parts of small weight. This method is also used to surfacing bronze crowns on steel hubs, bushings, shafts, etc.

ALLOYS
Aluminum bronze:
CuAI10Fe3, CuAI10Fe3Mn2, CuAI10Ni5Fe4
Tin bronze:
CuSn5Zn5Pb5-C, CuSn11P-C, CuSn10Pb10
Brass:
CuZn37Pb2, CuZn38Mn2Pb2, CuZn25Al5Mn4Fe3-C
In the future, it becomes clear that it is possible to prepare other alloys.
MACHINING
After receiving the castings, they are delivered to the machining department, where preliminary turning or milling machining of parts is carried out according to customer drawings.
UABRONZE LLC turns parts with diameter of up to 1000mm and mills parts up to 1000x400mm.
