Cost-optimized, ultra-flexible 50-Ohm RG174 CCA coaxial cable certified by ISO9001, CE, and RoHS. Engineered by Zhenjiang Worldpeak on a 2.60 mm copper-clad aluminum platform, it features a bare copper braid shield and a tight 15 mm bend radius, offering up to 40% BOM savings for indoor IoT devices and routers.
The Worldpeak RG174CCA coaxial cable is a highly cost-optimized, ultra-compact 50-ohm coaxial cable engineered on a durable copper-clad aluminum (CCA) conductor platform. With a slim 2.60 mm outer jacket diameter, this specialized RG174 CCA cable preserves the exact physical form factor of premium tinned copper variants. This makes the Worldpeak coaxial cable a perfect, seamless mechanical drop-in substitute for high-volume RF projects prioritizing bill-of-materials (BOM) cost reductions. It serves as a reliable solution for consumer electronics, indoor RF jumper links, and moderate thermal environments.
To optimize production costs, this RG174CCA coaxial cable balances cost efficiency with solid performance. Incorporating a copper clad aluminum cable core alongside a bare copper braided shield (BCBS) lowers raw material expenses by 30% to 40% compared to traditional tinned copper models.
This smart structural design introduces three critical engineering tradeoffs that B2B buyers must evaluate:
Electrical Conductivity: The aluminum core of the RG174 CCA cable delivers approximately 60% IACS conductivity compared to the 100% standard of pure copper.
Galvanic Corrosion Risk: Humidity at the conductor-shield junction can trigger galvanic reaction over long periods.
Braid Oxidation: The bare copper braid gradually oxidizes under humid conditions.
To address these parameters, Worldpeak designs this specialized 50-ohm coaxial cable strictly for indoor, climate-controlled environments where these specific material properties align perfectly with your product's target lifespan.
Optimal Cost-to-Performance Ratio: Selecting this RG174CCA coaxial cable reduces manufacturing expenses by up to 40% over standard copper cables.
Drop-In Mechanical Fit: The exact 2.60 mm outer diameter allows immediate integration into current assembly lines without tooling changes.
High Shielding Effectiveness: The robust bare copper braided shield guarantees stable signal integrity for short-run connections.
Flexible Deployment: The solid PE dielectric coupled with a flexible PVC jacket ensures a tight static bend radius of 15 mm.
Certified Manufacturing: Every batch of Worldpeak coaxial cable complies with CE, RoHS, FCC, and UL94 standards.

Processing a copper clad aluminum cable demands stringent quality control protocols. The thin copper cladding on the aluminum core accounts for 10% of the wire cross-section. Worldpeak utilizes cross-sectional metallography at the raw material inspection stage to verify cladding uniformity. A variation in cladding thickness below 8% can cause high-resistance zones, creating localized hot spots under continuous RF currents.
Additionally, the tensile properties of the RG174 CCA cable must be monitored. Aluminum exhibits lower tensile yield strength (~55 MPa) than copper (~210 MPa), leaving the strands vulnerable to necking during high-speed twisting. Worldpeak measures strand elongation after every production run to ensure the outer copper layer remains unbroken.
For the bare copper braided shield, oxidation is natural when exposed to ambient humidity. While this copper oxide layer is self-limiting, it increases the surface contact resistance of the braid over 6 to 12 months in unconditioned storage. For applications requiring long-term shelf storage without performance changes, Worldpeak recommends using tinned copper versions.
This premium RG174 RF cable is ideal for several B2B sectors:
Consumer Electronics Interconnects: Ideal for internal jumper assemblies in routers, modems, and set-top boxes.
Low-Cost IoT Sensor Nodes: Serves as a budget-friendly internal link in smart meters, security systems, and environmental sensors.
Automotive Cabin Accessories: Excellent for short, indoor GPS, DAB, and cellular antenna routing.
Prototyping & Educational Kits: Widely utilized in university engineering labs, hobbyist kits, and amateur radio setups.

Q: Does the RG174CCA coaxial cable perform differently than tinned copper models?
A: At frequencies under 500 MHz and runs under 2 meters, the difference in signal loss is less than 0.3 dB. The RG174 CCA cable performance variation only becomes noticeable at lengths over 3 meters or frequencies above 1 GHz.
Q: Is this 50-ohm coaxial cable compatible with Power-over-Coax (PoC)?
A: Yes, but only for low-power setups below 500 mA. Because this copper clad aluminum cable has higher DC resistance than solid copper, higher current causes a larger voltage drop.
Q: Can I dual-source and mix this product with tinned copper alternatives?
A: Yes, both variants maintain a stable 50-ohm rating. However, because bare copper braid can oxidize faster than tinned copper, we advise checking long-term EMI shields when switching. Contact Worldpeak to obtain complete testing data for your system qualification.
