A: Standard orders take 4-6 weeks; expedited options available.
Glossary of Terms
IACS: International Annealed Copper Standard (measures conductivity).
ETP Copper: Electrolytic Tough Pitch Copper (high conductivity).
Electrolytic Tough Pitch Copper (ETP Copper – C11000): High-purity Copper (≥99.90% Cu) with excellent conductivity (100% IACS), used in electrical applications.
Oxygen-Free Copper (OFHC – C10100): Ultra-pure Copper (<0.001% oxygen), ideal for high-vacuum and critical electrical systems.
Bare Copper: Uncoated Copper with natural corrosion resistance, used in grounding systems.
Tin-Plated Copper: Copper coated with a thin Tin layer to prevent oxidation in humid environments.
