Straight Copper Tube

Copper Tube: Premium Conductor with the Widest Size Range in China for Diverse Applications

Product Overview

Our Copper Tube (also known as Pure Copper Tube) is a high-performance metal conduit crafted from high-purity copper (purity ≥ 99.9%) through advanced extrusion, drawing, and annealing processes. What sets us apart is that we offer the widest product size range in China—covering almost all common and customized specifications to meet every possible demand from industrial, construction, and consumer sectors. Beyond its exceptional electrical conductivity, thermal conductivity, and corrosion resistance, our Copper Tube’s extensive size options eliminate the hassle of sourcing from multiple suppliers, making us your one-stop solution for copper conduit needs. Whether for large-diameter industrial pipelines or micro-diameter precision components, we have the right size to match your project requirements.

Core Features & Advantages

• Widest Size Range in China: We lead the market with an unparalleled size portfolio—outer diameter from 2mm to 300mm, wall thickness from 0.3mm to 20mm, and length from 0.5m to 6m (customizable up to 12m for special orders). This comprehensive range covers micro-tubes for electronics, standard tubes for plumbing, and large-diameter tubes for industrial engineering, ensuring we can fulfill any size request in China.
• Superior Material Purity & Performance: Made of 99.9% high-purity copper, our Copper Tube delivers exceptional electrical conductivity (≥ 98% IACS) and thermal conductivity (≥ 380 W/(m·K)), outperforming alloy tubes in energy transmission and heat dissipation. It is ideal for applications requiring efficient current or heat transfer, such as HVAC systems and electrical busbars.
• Excellent Corrosion Resistance: The dense copper structure forms a natural protective oxide film on the surface, effectively resisting moisture, acidic/alkaline substances, and atmospheric oxidation. Even in harsh environments like marine or industrial areas, it maintains long-term structural integrity, with a service life of over 50 years in standard applications—far exceeding that of steel or plastic tubes.
• High Mechanical Strength & Ductility: Through precision annealing, our Copper Tube balances mechanical strength (tensile strength ≥ 200MPa) and ductility (elongation ≥ 35%), enabling easy bending, cutting, and welding without cracking. It can withstand moderate pressure (up to 2.5MPa for standard wall thickness) and mechanical vibration, adapting to complex installation scenarios.
• Eco-Friendly & Recyclable: Copper is 100% recyclable without loss of performance, and our production process adheres to green manufacturing standards (compliant with RoHS and REACH). Using our Copper Tube reduces environmental impact, aligning with global sustainable development goals for construction and industrial projects.
• Consistent Quality & Precision: Each Copper Tube undergoes strict quality control, with dimensional tolerance as tight as ±0.01mm for micro-tubes and ±0.1mm for large-diameter tubes. The smooth inner/outer surface (Ra ≤ 0.2μm) minimizes fluid resistance (for plumbing) and ensures stable signal transmission (for electrical applications), avoiding performance issues caused by uneven dimensions.

Technical Specifications

Typical Applications

With the widest size range in China, our Copper Tube serves diverse industries and scenarios:

• Plumbing & HVAC: Standard-size tubes (OD 15mm - 50mm) for residential/commercial water supply, heating, and air conditioning systems—leveraging corrosion resistance and thermal conductivity.
• Industrial Engineering: Large-diameter tubes (OD 100mm - 300mm) for chemical pipelines, oil/gas transmission, and power plant cooling systems—handling high pressure and harsh media.
• Electronics & Precision Components: Micro-tubes (OD 2mm - 10mm) for electronic device cooling, sensor casings, and PCB heat dissipation—meeting miniaturization requirements.
• Construction: Medium-size tubes (OD 20mm - 80mm) for architectural handrails, decorative structures, and solar water heater pipelines—combining durability and aesthetic appeal.
• Automotive & Aerospace: Custom-size thin-wall tubes (OD 5mm - 30mm, WT 0.5mm - 2mm) for automotive fuel lines, brake systems, and aerospace hydraulic pipelines—withstanding vibration and extreme temperatures.

Quality Assurance

Our Copper Tube is produced in ISO 9001 and ISO 14001-certified facilities, with a strict quality management system covering raw material selection (high-purity copper ingots), production (precision extrusion/drawing), and final inspection. To ensure the accuracy of our wide size range, each batch undergoes:

• Dimensional testing (using laser diameter gauges and thickness meters) to confirm compliance with the ordered size;
• Material purity analysis (via X-ray fluorescence spectrometry);
• Mechanical performance testing (tensile strength, elongation) and pressure resistance testing;
• Corrosion resistance testing (salt spray chambers) and surface quality inspection (optical microscopes).

As the provider of the widest Copper Tube size range in China, we offer full customization—including non-standard outer diameters, wall thicknesses, lengths, and surface treatments (e.g., tin-plated, nickel-plated). Our technical team provides one-on-one pre-sales consultation to help you select the right size, and after-sales support to address any application issues.
