Physical Properties
Low Phosphorus, High Hardness Electroless Nickel
Process Low Phosphorus Electroless Nickel-NI-426 is design
for functional engineering applications that require
increased hardness as well as the standard corroion
protection of Electroless Nickel.
Deposits of Low Phosphorus Electroless Nickel NI-426
have very high as-plated hardness value (650 to 700
HV100) similar to thoses of electroless nickel-boron
and provide superior wear preformance compared to otehr
electroless nickel-phosphrus depo sits. Low Phosphrus
Elkectroless Nickel NI-426 deposits are uniquely suited
for many engineering applications. In addition, this
process has a high melting temperature(-2000 degrees
F.) which ads to its functionality for many applications
including those requiring improved erosion resistance.
The high hardness, low stress, high melting temperature
and improved conductivity makes Low Phosporus Electroless
Nickel NI-426 ideally suited for electronic compent
application that require solderability, brazing, or
welding capabilities.
This Process chemically deposits a uniform nickel
phosporus alloy and is capable of plating a wide variety
of substrates
Low Phosporus Electroless Nickel NI-426 meets MIL-D-26074E
and AMS 2404C specifications.
Features of the Low Phosphorus Electroless Nickel

UNIFORM DEPOSIT
One big advantage that "Electroless Nickel" has
over electrolytic plating is that there is virually
no build-up on edges. Build-up occurs on parts being
electroplated due to the high current density at these
points. This is evident with heavy de position when
precautions are not taken for masking and special anoding.
Because our process is autocatalytic, no current is
required. As a result, edge build-up is eliminated.
In addition, post plating, grinding and polishing are
minimized thus effect ing labor savings.
