BALL BURNISHING
Tumbling parts with hardened, highly polished steel balls or other shaped media in a
chemical cleaning solution.
It is especially used to polish softer and malleable metals. Burnishing is sometimes used
to improve the final luster.
BAR CHART
A bar chart is a graphic representation which compares quantities by means
of rectangles ( bars )
of uniform widths and of lengths proportional to the number
being represented. ars make it easy
to recognize small differences in quantities or frequencies, and
compare one category with another.
Easy to construct.

BEARING ALLOY
Bearing Alloy consist of 80% tin, 10-13% antimony, 5-10% copper and 0.5-3% lead
BENCHMARKING
The practice of setting operating targets for a particular function by
selecting the top
performance levels, either within or outside a company's own
industry. In a broader
sense, benchmarking involves searching around the world for new
ideas and practices
for the improvement of processes, products, and services.

BRASS
An alloy consisting of copper and zinc. Yellow brass contains 70% copper and 30% zinc. Red
brass contains 80% copper and 20% zinc.
BRIGHTENER (ADDITIVE)
A chemical added to a plating bath to brighten and improve other deposit characteristics.
BRIGHT PLATING RANGE
The current density range in which a plating solution produces acceptably bright deposit.
BRONZE
An alloy consisting of copper and tin.
BURNISHING
Tumbling parts to be polished with each other or with glazed beads, soap
and a burnishing compound.
BURNISHING COMPOUND
It contains soap and other buffering chemicals to prevent tarnishing. It maintains a
specific range of pH in operation.
BURNT DEPOSIT
A rough, non-coherent deposit produced by plating at high current density. This deposit
usually contains oxides or other inclusions.
