Copper wire M16 is a highly sought-after product in the electrical and manufacturing industries due to its excellent conductivity, corrosion resistance, and durability. Widely used in power transmission, automotive wiring, and various industrial applications, Copper wire M16 offers a reliable solution for high-performance requirements. With precise M16 specifications, this type of copper wire ensures compatibility and efficiency in demanding environments, making it a preferred choice for engineers and procurement specialists looking for consistent quality and optimal performance.
Copper wire M16 is defined by its metric size classification, where “M16” generally refers to a thread or diameter standard in millimeters. For copper wires, this translates into a substantial thickness suitable for heavy-duty electrical or grounding applications.
Manufactured from high-purity electrolytic copper (minimum 99.9% Cu)
Meets international standards such as ASTM B3, IEC 60228, and JIS H3100
Free from impurities like sulfur and lead that could compromise conductivity
The high copper purity guarantees low electrical resistance, making it an excellent choice for high-current and low-voltage drop applications in both industrial and infrastructural systems.
Nominal diameter: approximately 16 mm
Tolerance level: ±0.05 mm for precision installations

When used with protective coatings or insulation, the lifespan of M16 copper wire can exceed several decades, ensuring long-term investment efficiency.
PVC: Offers cost-effective protection for indoor applications
XLPE (cross-linked polyethylene): Preferred for outdoor and high-voltage use due to heat and chemical resistance
The selection of insulation is crucial depending on the application’s thermal, mechanical, and environmental stress levels.
Bare copper: Standard for most dry or enclosed environments
Tinned copper: Provides added protection against oxidation and chemical corrosion, ideal for marine and underground use
Tinned copper M16 wire is particularly valuable in corrosive settings, extending the operational life of electrical systems significantly.
Supplied in coils, drums, or spools depending on quantity and application
Coil lengths typically range from 50 to 500 meters
Industrial drums available for large-scale infrastructure projects
Proper packaging of Copper wire M16 ensures ease of transport, efficient on-site handling, and prevention of mechanical damage or contamination during storage.
Store in a dry, dust-free environment to avoid corrosion
Avoid direct contact with the ground or chemically active surfaces
Use lifting equipment for heavy drums to prevent personal injury and wire distortion
Maintaining the integrity of the wire during handling is essential for safety and long-term performance, especially in environments with temperature or humidity fluctuations.
Complies with RoHS and REACH regulations (free from hazardous substances)
Fire-retardant insulation options available upon request
Documented material traceability and quality certificates (Mill Test Certificate – MTC)
Copper wire M16 not only meets industrial safety standards but also helps businesses align with environmental and regulatory frameworks, reducing liability and enhancing brand responsibility.
Copper offers 60% higher conductivity than aluminum
Higher tensile strength reduces the risk of breakage during installation
Smaller diameter required for same current-carrying capacity
While aluminum is lighter and cheaper, Copper wire M16 is preferred in critical applications where reliability, heat resistance, and long-term performance outweigh upfront material cost.
Copper carries electrical power; fiber optics transmit data
In hybrid systems (e.g., telecom towers), both are often used in parallel
Copper remains essential for grounding and power circuits
Though fiber optics are revolutionizing data transmission, Copper wire M16 maintains irreplaceable roles in power delivery, surge protection, and structural bonding.
Copper is 100% recyclable without performance loss
