CA102 is an aluminium bronze traditionally used for decorative work due to its rich 18 carat gold colour, its excellent cold rolled surface finish and its ability to be deep drawn.

In addition to its high strength, it also features excellent corrosion resistance in various acid and saline waters. CA102 is highly resistant to wear, abrasion and tarnishing and is the only truly cold workable aluminium bronze available.
