Phosphor Bronze Wire

Phosphor Bronze is used in a variety of traditional instruments such as the sitar, surbahar, santoor, and cimbalom.

Alloy: 510 - Grade A spring temper phosphor bronze wire (95% copper, 5% tin, nominally); meets industrial specification ASTM B 159
 
Chemical Composition:
Sn (tin) 4.6-4.9%, P (phosphor) 1.6-2%, traces (<.01%) of Fe(iron), Pb (lead) and Zn (zinc)
balance is Cu (copper)
 
Tensile Strength:
145,000 PSI minimum .025" diameter or less
135,000 PSI minimum (9490 kg/sq cm) over .025" diameter
 
Diameters: .008" (.20mm), 009" (0.23mm), .010" (0.25mm), .011" (0.28mm), .0125" (0.32mm), .014" (0.35mm), .016" (0.40mm), .018" (0.45mm), .020" (0.51mm), .0225" (.057mm), .025" (0.63mm), .0285" (0,71mm), .032" (0.80mm), .036" (0.90mm), .040" (1.0mm), .045" (1.12mm), .048" (1.20mm), .051" (1.27mm), .057" (1.42mm). These diameters are rounded to the nearest thousandths from the diameters of the B&S gauge system.
 
Quality available:
Industrial Quality - from China, Mexico and the US; meets industrial specifications; diameters .016" and up
Premium Quality - custom drawn in the US to more stringent specifications as to ductility and tensile strength as demanded by the use in musical instruments; diameters .008" - .0285", .048", .051"
