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".
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.
Cast plaques are manufactured using sand molds in our state-of-the-art foundry from raw
ingot alloyed in the following materials:
Equivalent to Copper Development
Association Alloy. C92200, 88%
copper, 6% tin, 4% Zinc, 2% lead.
Cast from Aluminum Association Alloy
Designation C443.2.
(Aluminum is approximately 1/3 the weight
of bronze.)
