PROCESS
Decorative Chrome
Decorative chrome is a multi step process resulting in a highly
reflective finish. All parts are stripped of paint, old plate or
scale, down to the base metal. The next step is to polish with
various grits to obtain a satin finish. The polishing process is
the foundation for an excellent finish. Depending on the type of
metal, the condition of the metal and the configuration, the
price to refinish the part can vary drastically. Once the part
is uniform the copper plate is applied. The next step is to buff
the copper to a mirror finish and inspect for flaws. Once the
part passes inspection it is ready to nickel plate and the final
chrome plate. Decorative chrome is designed to enhance the
appearance and retard corrosion. To retain that high luster it
is important for you to use very soft cloths when washing and
wax the chrome as often as possible after the wash. The waxing
seals the plate, much as it does on painted surfaces and keeps
your parts looking their very best.
Decorative Nickel Plate
Decorative nickel is applied the same way as decorative chrome,
except the final chrome layer is left off. Nickel has a yellow
white appearance where as chrome has a white look. The corrosion
protection is reduced when the chrome is left off and for that
reason the parts should only be used in doors. Cabinet hardware,
guitar parts, piano hinges, and other interior uses are common.
Nickel can be very bright and shiny like chrome or many times
the surface is brushed to get the stainless steel satin look.
Electroless Nickel
Electroless nickel (EN) is a coating applied for corrosion
protection. IT is more expensive to apply than zinc but offers
better protection. The nickel is applied from a chemical
reaction rather than an electrical current like decorative
nickel. For that reason, the plate thickness is uniform
throughout the part where ever the solution touches the metal.
EN is often used in the food industries where rust can not be
exposed to the processing. Other uses are highly corrosive
atmospheres, like salt water or underground in drilling
applications.
Copper
Copper is used as an underlay for many of the decorative
finishes. It is easy to apply and allows for easy work when
buffing closing minor pits and buffing lines. In some instances
copper is used for a decorative finish, often in the kitchen and
fireplace areas of the house. The copper is buffed to a high
shine but will tarnish if not protected from oxidation. Many
times the oxidation is advanced to a greenish black stage,
lightly buffed and sealed to get the "old" or antiqued look.
Copper is also an excellent conductor for electricity and is
used in the circuitry industry.
