Sliding bearings a21

1. Structure

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

a21 - Sliding bearings a21
4. Lubrication

Requires efficient lubrication system.
