Pinion wire is sold in 1, 3, and 5 foot lengths with unfinished ends and a ±0.5 inch length tolerance. It is available in brass and steel with 14-1/2° and 20° pressure angles, 64 pitch, and tooth counts from 10 to 26. The 12-tooth variant in 20° pressure angle and 5-foot length is cataloged as A 1B 9-Y64 012 for brass and A 1C 9-Y64 012 for steel. The part number A 1C 9-Y645012 is not listed; the correct designation for 12 teeth is A 1C 9-Y64 012 without the '5' digit. Material is limited to brass and steel as stated, with no mention of carbon steel.
The material of pinion wire is dragged through the dies; it is referred to as "drawn" steel, a process that begins with melting several metals together, typically iron plus an additional metal type that is a crucial part of the alloy (smelting). After being slightly cooled, the metal is then coated with a drawing lubricant and pulled through the dies, which form its teeth. The metal cannot be dragged through the dies that shape it without this lubrication.
When a stock gear is not available, spur gears can be made using SDP/SI pinion wires. Available in the following pitches: 64, 48, 44, 32, and 24 (modules 0.4, 0.5, and 0.8) in steel and brass. Other lengths are available upon request.
Steel spur gear stock is also offered in pitches 48, 32, 24, and 20 (modules 0.8 and 1) and is used to make spur gears.
