1kg Copper Bullion Bar .999 Fine Copper

One kilogram of copper. One solid bar. A serious piece of metal.

The 1kg copper bullion bar is Williams Bullion's largest single-piece copper product — and there's nothing quite like holding a full kilogram of .999 fine copper in your hands. Solid, weighty, and struck with a clean bullion finish, this bar is a statement piece for any physical metals collection.

Where our 1kg package of 5oz bars gives you flexibility across multiple pieces, the 1kg bar gives you something different a single, unified piece of copper that stores simply, displays impressively, and represents a genuine commitment to physical metal ownership.

For New Zealand investors building a long-term copper position, the 1kg bar is the logical next step after tubes and rounds. At $239, it delivers exceptional weight for the price and sits comfortably in a safe, a display case, or a stack alongside other large-format bullion.

Copper's industrial importance continues to grow globally. Electric vehicles require significantly more copper than combustion engines. Solar panels, wind turbines, and grid infrastructure all depend on it. Owning a kilogram of physical .999 fine copper puts you at the intersection of tangible asset ownership and genuine industrial demand something no paper investment can replicate.
