Silicon Bronzes are part of the subgroup of high-strength
brasses. They contain less than 20% zinc and up to 6% silicon
and are solid solution strengthened. Silicon red brasses
are used for valve stems where corrosion resistance and
high strength are critical. Included in this category are the
silicon red bronzes, which are similar to silicon red brasses
except for their very low concentrations of zinc. They are
used to make bearings, gears and intricately shaped pump
and valve components.
Nickel Silvers, also called nickel brasses, are alloys containing
copper, nickel, and zinc. Though they do not contain
silver, they have an attractive silver luster, moderately high
strength and good corrosion resistance. They are used to
make food and beverage handling equipment, decorative
hardware, electroplated tableware, optical and photographic
equipment and musical instruments.
