Materials
Prime Aluminum (Alloy #356) ingots are used for all
aluminum plaques. Plaque faces are stroke-sanded
with baked enamel backgrounds before being
clear-coated and oven-baked with a two-part hardened
clear matte lacquer.
Prime Bronze (FederalAlloy) ingot 89833 are used
for all bronze plaques. This alloy is lead and
mercury free. Plaque faces are stroke-sanded with
baked enamel backgrounds before being clear-coated
and oven-baked with a two-part hardened clear matte
lacquer. Optional finishes include oxidized or patina.
Bronze castings are the
material of choice for interior as well as exterior
applications. Although the finish of bronze will
naturally patina over time, the material itself will
not deteriorate. Objects made from bronze have been
found submerged in seawater for over 3000 years still
in excellent condition.
The weight of a bronze plaque may be roughly estimated
by calculating the plaque's volume in inches (height x
width x depth) x .31. For most smaller plaques (under
36" x 30") allow .25" as the approximate depth. Use
.375" for plaques over 36" x 30".
Example: For a 36" x 24" plaque calculate 36" x 24" x
.25" = 216 cu. inches x .31 = 66.96. The plaque's
estimated weight would be 67 lbs.
An aluminum plaque is approximately 1/3rd the weight
of a comparable sized bronze plaque. In the above
example, simply divide the answer by 3. A 36" x 24"
aluminum plaque weighs approximately 23 lbs.
