SINT-A50 Sinterbronze (Sintered Bronze)

SINT-A50 is a low-density tin bronze sintered bearing material per DIN 30910-3. Standard material (preferred grade). High porosity provides maximum oil retention for self-lubricating bearing applications.

Chemical Composition (per DIN 30910-3 (Sintered Metals for Bearings))

Element	Content
Cu	Rest (Balance)
Sn	9–11%
C	< 0.2%
Other	< 2%

Properties (per DIN 30910-3 (Sintered Metals for Bearings))
