Dural-G's Applications
 

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:

Abrasion coefficient
μ

Compression strength
MPa (N/mm2)

Hardness
HB

CuAl10Ni5Fe5
0.280
540
160
DURAL-G
0.187

Testing result:

  1. DURAL-G is working on same durability parameters as bronze CuAl10Ni5Fe5
  2. 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
  • Mechanical properties
Compression strength
Mpa (N/mm2)

Hardness
HB

CuSn12

Testing result:

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