Not all bronze is the same. Bronze is defined by what's mixed with copper, and the specific blend determines its character. We work exclusively with 90-10 tin bronze — 90% copper and 10% tin — which is widely regarded as the gold standard for cast plaques and architectural metalwork.

This traditional alloy delivers:

• Rich, warm color — the classic golden-amber tone people associate with timeless, prestigious metalwork
• Exceptional durability — tin bronze resists corrosion, oxidation, and weathering, even in coastal or high-humidity environments
• Fine casting detail — the alloy flows smoothly when cast, capturing sharp lettering, fine borders, and intricate artwork with precision
• Long-term stability — properly cared for, a tin bronze plaque will last generations without structural degradation
