Phosphor Bronze Wire

Phosphor bronze is a copper-tin-phosphorus alloy family available in different tempers, with strength and formability distinct from cartridge brass. Direct data: Density: 8.7–8.9 g/cm³; Wire diameter: 0.08–0.40 mm; Hardness: about HV 120–250; Brush operating range: -20–200°C; Electrical conductivity: about 10–20% IACS.

Electrical contact, resilient conductive brushing and gentle cleaning where steel contamination is undesirable.

Phosphor Bronze Wire changes brush stiffness through filament diameter, free trim, density, crimp, and contact. Use finer filament and longer trim for conformable contact; use coarser filament, shorter trim, or higher density for stronger displacement or cutting.

Compare Phosphor Bronze Wire with Compare with brass for softer copper-alloy contact, copper for conductivity and stainless wire for stronger cutting. Change material when wet stiffness, temperature, chemical resistance, conductivity, particle shedding, or surface marking becomes the limiting factor.
