I am seeking the material properties of nickel with the use of electroless nickel plating process. The desired data is similar to the table below

TABLE I — Material Properties of Hard Gold, Palladium and Palladium Alloys
Materials Properties	Hard Au	PdNi* Pd*	PdCo* (20 wt%)	(20 wt%)
Grain Size (Å)	200-250	60-2000	50-220	50-150
Density (g/cm³)	17.3	11.7	10.7	10.8
Thermal Stability (C)	150	‹450	380	395
Hardness (KHN₂₅)	140-200	150-500	450-550	590-640
Ductility (E% @ 2.5mm)	‹3	3-‹10	3-‹10	3-7
Porosity Index
--Connector Pins (1.5mm/2.5mm Ni)	0.7	--	0.11	0.02
--Laboratory Coupons (on 1cm² surface, 1mm GFPdX)	3.7	0.7	0.4	0.2
Wear Properties (load: 100g)
--Cycles to failure (x1K)	20	‹80**	35	‹80
--Coefficient of Friction @ 10K cycles	0.60	31**	0.55	0.43
Relative Cost (Pd/Au)	1.00	0.63	0.46	0.47
