Palladium · 16% IACS

Palladium-Plated Contact

Palladium plating over nickel underplate, used on connector contact surfaces in industrial / instrumentation applications. Higher mating-…

Composite · n/a% IACS

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…

Composite · depends on base metal% IACS

Litz Wire Construction

A construction style, not a material: each strand is individually enamel-insulated then twisted with other insulated strands. Forces curr…

Alloy · 98% IACS

Gold-Plated Copper

Copper conductor plated with gold. Used where corrosion resistance dominates (humid environments, marine, military) rather than for raw c…

Alloy · 103% IACS

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…

Silver · 106% IACS

Monocrystal Silver

Pure single-crystal silver, typically 6N (99.99997%) purity. The highest-conductivity conductor in routine audio use (~106% IACS), but ex…

Copper · 102% IACS

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…

Copper · 101% IACS

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%…
