This product has high technical content, especially the extremely low oxygen content, which can reach below 5ppm, and the copper+silver content is above 99.99%. It has high electrical conductivity, and the electrical conductivity reaches 101 (IACS%). The diameter is 18 mm and can be bent for 120 degrees without any crack.
Oxygen Content: ≤ 5 ppm — Virtually oxygen-free, eliminating hydrogen embrittlement risk
Copper + Silver Purity: ≥ 99.99% — Near absolute purity
Electrical Conductivity: 101% IACS — Exceeds international annealed copper standard
Diameter: 18 mm
Bend Capability: 120° bend without surface cracking
The "(Big)" designation indicates this is the larger diameter variant within our trapezoidal copper product family, suitable for high-current applications.

FAQs
Q1: What does 101% IACS conductivity mean?
IACS (International Annealed Copper Standard) sets the benchmark for pure annealed copper at 100%. Achieving 101% IACS indicates conductivity 1% higher than the standard reference — a result attainable only through extreme material purity and optimized processing.
Q2: Why is oxygen content below 5 ppm critical?
In hydrogen-rich or high-temperature environments, copper with higher oxygen content can undergo hydrogen embrittlement, causing internal cracking and failure. Maintaining oxygen ≤5 ppm eliminates this risk entirely.
Q3: Can the 18 mm diameter wire truly bend 120° without cracking?
Yes. Our specialized annealing process imparts excellent ductility, allowing a 120° bend under standard bending practices without surface cracking or internal defects.
Q4: What does "(Big)" signify in the product name?
"(Big)" designates this as the 18 mm diameter variant within our trapezoidal copper product line. Smaller diameter options are available under the standard "Trapezoidal Copper Platoon" designation.
Q5: Is custom diameter or true trapezoidal cross-section available?
Yes. We can produce custom diameters and true trapezoidal cross-sections per customer drawings. Please contact our engineering team with your specific requirements.
