In all known fields of anti-friction metals (bronzes)
applications.
Fields of application
- tractors (change gears, water pump)
- machine-tools (lathe, cutter, grinder)
- agricultural machines (harvesting-machine,
seeding-machine)
- mining industry (belt-carrier)
- electro-techniques (washing machine, sewing machine)
- textile industry (spinning machine, weaving machine)
- food industry (blending machine, wrapping machine)

Example of extreme applications
a) Strength to high wear and temperature
-
Place of application: Rolling mill 3 MECHEL, Campia Turzii, Romania
-
Naming part: “Guiding jaw for finishing wire rolls”
  
-
Working conditions for casting part: semi-finished temperature : 9500 – 10000C; semi-finished moving speed 35 m/s
-
Used material: bronze casting part CuAl10Ni5Fe5
-
Proposed material: DURAL-G casting part
-
Mechanical properties:

Testing result:
- DURAL-G is working on same durability parameters as bronze CuAl10Ni5Fe5
- Cost price for DURAL-G is with 30% lower price then bronze
b) Resistance to abrasion wear and shocks
- Place of application: “Prototype flanker SCHRADER” for rubber wear tyre crushing, tested to MINESA ICPM - Cluj, Romania
- Naming part: “Crown snail gear”
- Working conditions for casting part: Installed power 90kW, crushing productivity 4 t/h
- Used material: there ware tested several bronze casting part high alloyed with Sn (CuSn12), but the material did not resist to mechanical shocks
- Proposed material: DURAL-G casting part

Testing result:
- Gave up to bronze CuSn12 to Crown snail gear because it nor resist to mechanical shocks
- Dural-G resist to required technical conditions
DURAL-G is with 30% lower price then bronze |
