with excellent resistance to chemical
and corrosive attack by all but the
most severely oxidising agents. Tests
to ASTM-B117 show Neutral Salt Spray
corrosion resistance up to 1000 hours.

LOW COEFFICIENT OF FRICTION
T h e
Ph os ph o r ous
co n t ent
of
Electroless
Nickel provides
natural
lubricity
and helps minimise
heat
build-up, reducing galling and scoring.
The coefficient against Steel of 0.13
lubricated
( 0.14
dry)
proves
the
excellent frictional properties, being
approx.
one
half
that
of
steel.
