SAE-863 Iron-Copper Alloy (Cu20-Fe80) Sintered Bearing Material

SAE-863 is an iron-copper (Cu20-Fe80) base, oil-impregnated sintered self-lubricating bearing material per Soperb FZ14 standard. Equivalent to SAE 863 / MPIF FC-0205-K35 specifications. Combines the strength of iron with the conductivity and corrosion resistance of copper. Ideal for electrical motors, textile machinery, and high-speed bearing applications.

Chemical Composition (Soperb FZ14 / SAE 863 / MPIF FC-0205-K35)

Element	Content
Cu	18~22%
Fe	Balance
C	≤0.3%
Other	≤2.0%

Mechanical & Physical Properties

Property	Value
Oil Retaining	17%~19%
Radial Crushing Strength	>210 MPa (at 19% oil), >280 MPa (at 17% oil)
Max. Linear Speed	15 m/s
Max. PV	8 N/mm² · m/s
Hardness	HB 30~60

Products Standard: ISO 2795 (DIN 1850 Part 3). Radial crushing strength values are shown at corresponding oil retaining levels — higher oil content reduces crushing strength. All materials are oil-impregnated via vacuum soaking process.
