Our Cathode

At CAID, we understand that your tankhouse is an important asset and that your plant’s production is critical to your company’s success. Far too often, we see clients treat cathodes as an interchangeable commodity. With millions of dollars invested in your facility, you want the best-performing cathode to maximize your throughput. We have been optimizing our cathode design and construction for over 50 years. The CAID cathode is a premium product designed to get the most out of your tank house.

  • Solid copper bar ensures maximum current efficiency, reduces heat generation and wasted energy.
  • Every bar is labelled with its year of manufacture and a serial number, allowing operators to track the cathode’s history.

  • Patented I-TACC-XL weld creates a seamless bond between the solid copper bar and stainless steel sheet while allowing ease of repair.

  • A laser marked QR code allows full traceability of each cathode, from initial assembly through each repair cycle. 

  • Highest quality Stainless Steel sheet developed specifically for cathode use. Increases plating rate, improves separation of plated copper while reducing pre-strip.

  • We will apply your preferred type of edge strip. 2-sided or 3-sided. We supply all major brands and styles of edge strip. If you prefer to install them yourself, we will prepare them to accept your preferred brand.

  • Fully customizable.  We will build your cathode to fit your plant. Customized features include: v-groove, corner notches, side holes, bar dimensions, sheet dimensions, window size and position

Cathode for every occasion:

Our tankhouse experts have seen it all and the CAID cathode has been optimized for every environment.  It performs equally well in electrowinning as electrorefining plants. Our cathode’s conductive efficiency reduces the generation of heat, but it can also withstand the heat when the inevitable occurs.

We also manufacture cathodes for different needs. Do you run a starter sheet facility?  CAID has mastered the production of mother blanks. We will work with you to determine the best solution for your specific needs.


Repairs & Maintenance

What really sets us apart is that our cathode performs consistently from the day it is shipped; it is simply the longest lasting cathode. This is due to its ingeniously simple and rugged design and the fact that it is the most repairable cathode on the market.

Tankhouse environments are tough. Cathodes are put through their paces. They are constantly exposed to heating and cooling cycles, violently flexed and bent in stripping machines, exposed to corrosive environments and many other challenging conditions. It is normal for them to require some TLC on occasion.  We guarantee that the CAID cathode is longest lasting cathode on the market and will perform the best. But even our cathodes need some attention once in a while.

Cathode repairs can be divided into two categories:


To maintain peak performance, cathodes need to be maintained. A minor repair may consist of:

  • Washing
  • Sheet Levelling (flattening)
  • Buffing
  • Straightening
  • Repairing/replacing edge strips
  • Bar straightening

When a cathode needs a bit more attention, this is where we stand apart from the competition. For a fraction of the cost of a new cathode, CAID can disassemble your existing cathode, treat the components to get them back to our specifications, and reassemble it. A repaired cathode performs in the same way as a brand-new one.

When we perform a major repair, we include :

  • Washing
  • Removing the bar from the sheet
  • Sheet Levelling (flattening)
  • Buffing
  • Straightening
  • Repairing/replacing edge strips
  • Bar straightening
  • Bar re-machining
  • Welding a bar

Our Clients

CAID works with all of the world’s major copper companies. Since we started making cathodes in 1974, we have supplied cathodes to all major tankhouses in the US Southwest and Mexico as well as other locations around the world.

With nearly 2 million cathodes supplied around the world, we support projects of all sizes. Whether it is a small order to replace some poor performing cathodes, or a greenfield project with tens of thousands of cathodes, we have the capacity to support you.

Our History

Founded in 1947, CAID industries has been a stalwart of the mining industry for more than 70 years and providing fabrication services across the Southwest USA. In 1974, CAID built its first cathode for the copper industry. And the rest, as they say is history.

CAID cathodes have been in continuous operation at facilities around the world for more than 50 years. This is a testament to the reliability of the cathode as well as to high level of service provided by CAID. We are obsessed with producing quality cathodes. We are convinced that you will see a dramatic improvement by using the CAID cathode in your tank house. You will see:

  • Lower power consumption
  • Better current efficiency
  • More even plating
  • Easier stripping
  • Long-term value due to repairability
  • Longer life

We are so confident in our product that we are willing to let you sample them at not cost.  Give us a call today to see how we can send you sample cathodes for you to test in your plant. We know that you will be impressed!
