Applications of Copper Bullion :
The copper bullion is used in many industrial applications despite its main purpose being an investment asset.
- Electrical and Electronics Industry Since copper is a very good conductor of electricity, the bullion is used as electrical wiring, busbars, and motor windings in power generation, transmission lines, transformers, circuit breakers, switchgear, and household wiring. It is also found in printed circuit boards (PCBs), connectors, microchips, semiconductors, and integrated circuits, where 99.9% commercially pure copper is required.
- Construction Industry The high corrosion resistance and durability of copper bullion make it useful for potable water supply lines, heating systems, gas lines, and fire sprinkler systems as tubes. It can also be used as roofing materials, gutters, downspouts, flashing, domes, spires, decorative facades, doors, window frames, handrails, and other architectural details.
- Transportation Sector Electric motors in cars and industrial machines use heavy amounts of it. Next to these, car manufacturers use it in radiators and wiring systems. Apart from these, it is also used in alternators, brake tubing, bearings, electric vehicle batteries, charging infrastructure, sensors, connectors, relays, switches, navigation systems, and infotainment modules.
- Renewable Energy Technologies Solar panels and wind turbines use it to move electricity from the source to the grid. You will also find bullion used as copper foils in Energy storage solutions like batteries.
Types of Copper Bullion
- Copper bars These are a very common shape. We make the solid copper bullion bar in many weights, including the copper bullion bars 1 kg size. They are easy to stack and store in a warehouse.
- Copper rounds These are flat and circular. They look like large coins and lack a face value. They are often very shiny and show the metal’s quality.
- Copper coins These are similar to rounds but often have specific designs or markings on them. Investors like them because they are easy to trade and store.
- Copper bullets These are shaped like real ammunition. They are unique pieces for collectors. We ensure every pure copper bullion bar and bullet meets our strict purity levels.
- Copper cubes These are solid blocks with six equal sides. They feel heavy in the hand and look good on a desk. They show off the natural colour of the metal well.
