ASTM B187 Copper Round Rod High Conductivity 99.9% Pure Copper Rod

ASTM B187 Copper Round Rod - High Conductivity 99.9% Pure Bars Custom Lengths

ASTM B187 Copper Round Rods are crafted from 99.9% pure electrolytic copper, delivering unmatched electrical and thermal conductivity for critical applications in power transmission, renewable energy, and precision engineering. Compliant with ASTM B187, EN 13602, and JIS H3250 standards, these rods are available in custom lengths (100mm–6m) and diameters from 5mm to 200mm, ensuring versatility for OEMs and contractors.

Key Advantages:

Ultra-High Purity: Cu ≥99.9%, oxygen ≤0.04% (ASTM B187) for minimal resistance and optimal performance.
Superior Conductivity: 101% IACS (International Annealed Copper Standard) at 20°C.
Precision Machinability: Tight tolerances (±0.03mm for ≤50mm, ±0.1% for >50mm) for CNC and lathe work.
Corrosion Resistance: Anti-oxidation surface treatment for harsh environments.
Global Compliance: RoHS, REACH, and ISO 9001-certified production.
Custom Solutions: Cut-to-length, polished/brushed finishes, and bulk packaging.
