MATERIAL DATA

Copper and copper alloys such as brass and bronze provide versatility and a range of benefits, making an excellent choice for architectural applications. These metals have a natural resistance to corrosion, which ensures longevity and reduces maintenance costs, making them ideal for almost any environment.

Dissimilar Metal Design has developed a number of custom architectural patinas on copper alloys, exhibiting a wide range of expression. These patinas from DMD can produce use a palette of aesthetics from different chemicals, heat, and technique to create gradients, textures, and depth on the metal surface.

Patinas develop in our shop, after fabrication and before installation, so the surface arrives consistent and ready for the field.
