Basically, we take a high-purity aluminun core and bond a copper outer layer to it using a cladding process—it's not just plating, the metals are fused together under pressure and heat, which is why the conductivity stays consistent through bends and draws down to 0.08mm or so.
The real trick with this stuff is skin effect, where high-frequency currents hug the outer surface of a conductor, so the copper layer does all the work while the aluminum core keeps the weight down by roughly half compared to solid copper wire.
You'll see this used a lot in CATV systems and RF applications, but it's not ideal for low-frequency power transmission where bulk conductivity matters more—stick to solid copper there if you don't want votage drops.
our company offer the copper percentage from 10% to 40% depending on your batch, and most buyers go with 20% or 30% for a good balance of cost and performance, but the 40% version has tighter tensile strength at about 180 MPa if you need more durability.
Custom spools or reels are avaliable, though we usually have stock in standard sizes like 1mm or 2mm diameters, but confirm lead time for anything below 0.5mm or above 10mm since those require a different drawing setup.
Also, the density runs about 2.85 g/cm³ for the 10% copper mix up to 3.63 for the 40%, which is pretty much half of pure copper's density—handy if you're running long cable runs in tight spaces.
Lead time is usually 2-3 weeks for custom copper percentages, depending on the volume. If you need a rush order, let us know and we can check if we have stock on standard 20% or 30% blends.
Yes, we include ISO9001, CE, and RoHS certificates with every bulk order. If you need specific mill test reports or resistivity verification, just mention it when placing your order.
Absolutely—we can send a small sample spool of any diameter from our range, including 0.08mm. There's a nominal fee for shipping, but we'll deduct it from your first bulk order.
For diameters 5mm and above, the MOQ is typically 100 kg. Smaller gauges like 0.08mm have a lower MOQ of 10 kg. We can adjust based on availability, so just ask.
We package on spools or reels based on the diameter and quantity you order. For storage, keep it in a dry, temperature-controlled area—our standard wrapping prevents oxidation for up to 12 months.
Excellent experience overall. The shipping was remarkably fast, arriving several days ahead of the estimated schedule, which was a very pleasant surprise. The packaging was secure and professional, ensuring the spools arrived in perfect condition without any damage or tangling. Regarding the quality, the wire itself appears to be manufactured to a high standard; the cladding is consistent and the spooling is neat. The service provided was responsive and helpful when I had a pre-order inquiry about bulk pricing. They answered promptly and clarified the discount structure. While I have not yet used the product in an application, my initial inspection based on handling and visual check is very positive. The transaction was smooth from start to finish.
