Conductor materials
OCC copper, OFC copper, monocrystal silver, silver-plated copper, litz construction and more.
Palladium-Plated Contact
Palladium plating over nickel underplate, used on connector contact surfaces in industrial / instrumentation applications. Higher mating-…
MIL-Spec PTFE Insulation
PTFE (polytetrafluoroethylene, Teflon) jacket per MIL-W-16878. Lowest dielectric constant of the practical wire insulators (2.1 vs PVC’s…
Litz Wire Construction
A construction style, not a material: each strand is individually enamel-insulated then twisted with other insulated strands. Forces curr…
Gold-Plated Copper
Copper conductor plated with gold. Used where corrosion resistance dominates (humid environments, marine, military) rather than for raw c…
Silver-Plated Copper (SPC)
Copper conductor with a thin silver plating (typically 3–15 μm). At audio frequencies the skin effect concentrates current in the outer f…
Monocrystal Silver
Pure single-crystal silver, typically 6N (99.99997%) purity. The highest-conductivity conductor in routine audio use (~106% IACS), but ex…
OCC Copper (Ohno Continuous Casting)
Single-crystal copper produced by the Ohno continuous-casting process — a heated mold pulls the casting in a way that lets each grain gro…
OFC Copper (Oxygen-Free Copper)
Oxygen-free copper per ASTM B49 — multi-crystal copper with oxygen content held below 10 ppm. Baseline conductor for audio cables; ~101%…
