Nickel and Copper Plated
Jarden Zinc’s nickel-plated and copper-plated coin blanks are made using our proprietary high-speed electroplating process, producing a bright, high-quality finished coin blank. We can plate in single or multiple layers with various combinations of plated surfaces, typically using either steel or zinc as the base material. Zinc-based blanks require less plating thickness to achieve desired performance and require fewer processing steps. When copper is used for plating, it gives the coin blank a red finish. Jarden Zinc is commissioned to produce the Royal Canadian Mint’s multi-ply, nickel-copper-nickel technology.
Brass and Bronze Plated
We utilize our patented alloy-plating technology in both brass- and bronze-plated blanks, yielding a more consistent, reliable product for most typical commercial coinage applications. For brass plating, we combine copper and zinc; and for bronze plating, we combine copper and tin. The finished alloy is then deposited onto the blank surface in a plating bath. Other companies use a diffusion process that results in a less consistent and reliable product. Our capabilities include single- and multiple-plating layers for our brass-plated blanks, as well as bronze finishes in yellow, red and white. Typical base materials for our bronze-plated blanks are zinc, steel or nickel. The substrate is plated with a copper layer followed by a bronze layer.
