Premium quality aluminium bronze a21 forms coherent compact grain structure – achieved in unique forging technique
– different from standard rough grain structure of typical bronze alloys.
2. Chemical Composition
Aluminium (Al) – 13,10%
Iron (Fe) – 4,40%
Other (max) – 2,50%
Copper (Cu) – balance
3. Chemical and physical properties
4. Lubrication
Requires efficient lubrication system.
