depending on base metal. Will tarnish easily. Hardness varies from
90 Brinnell to about 135 Brinnell depending on process and plating
Solderability is excellent, but deteriorates with age.

excellent lubricity and smear characteristics for anti-galling uses on
static seals, bushing, etc. Stress relieve steel parts at a minimum
±25°F or more prior to cleaning and plating if they contain
or are suspected of having damaging residual tensile stresses.
