Engineered Conductor
Using a proprietary high-heat, high-pressure process, we permanently join high-strength steel or aluminum and the world’s highest quality copper (OFC). The copper protects the core metal from corrosion, and the core strengthens the copper. Offering the same electrical performance as solid copper and the strength of steel or aluminum, Copperweld is the best choice for demanding applications.
Distinctly Different
The reliability of a conductor depends on its core strength. Copperweld wire combines the strength of steel with the conductivity and corrosion resistance of copper. These properties are achieved by permanently welding a thick copper covering to a steel core — making Copperweld wire ideal for real world application threats like hammer blows, axe strikes, door pinches, and the punishing effects of mother nature.
Cost-Conscious
When used size-for-size (as in signal wire and rural grounding applications), Copperweld is both lighter and more reliable than copper, saving money. Whether you're protecting your power network, construction project, vehicle components, or your pocket, Copperweld's long life means big savings over time. Our conductors maintain spec-compliance long after most competitors' are replaced.
Bimetal Recycling
How do you beat a copper thief? Take away his financial incentive. Copper recyclers pay top dollar for solid copper scrap because it can be easily melted and sold at almost the market price of copper. Copperweld’s permanently-bonded copper covering can never be returned to virgin copper — making our conductors unattractive to recyclers and unprofitable for copper thieves.
Relieving Stress
Copperweld bimetal wire is annealed to relieve the mechanical stresses introduced from drawing the wire down to size. Annealing can make even steel-core wire bend like copper while remaining as strong as steel in tension and shear. Our finished products are ready to survive real-world application threats like hammer blows, axe strikes, door pinches, or the punishing back-and-forth abuse of wind.
Soft Bending
Copperweld is not stiff anymore — it feels better. (Yes, we've heard the complaints from linemen, too.) Today’s product offering includes stranded solutions that are soft to bend or train in the field and are even more flexible than copper. Of course, we can manufacture stiff, solid bimetallic for replacement of legacy material. Whether new or old, all of our products fit industry-standard copper connector sizes, too.
Continuous improvement
'Better' is not the accident of chance; it's the outcome of purpose. That's why we're always revisiting performance tests, improving manufacturing processes, expanding our product offering and diversifying market reach.
Dedicated support
With over 100 years of experience supporting and specifying mission-critical applications, the Copperweld sales, support and leadership teams are among the most knowledgeable subject matter experts in their fields.
Faster lead times
Made in the USA, Copperweld offers more than the quality and dependability that often comes with domestic manufacturing. Our strategic location allows us to offer bundled custom orders and provide lead times as short as 2 days shipped.
