Induction Annealing Copper Wire

Induction Annealing Copper Wire Objective: Induction Annealing a brazing copper wire for preform production. Material: Copper Nickel Silver 2774 Alloy rod 0.070" (1.8mm) diameter. Temperature 650ºF(343.3ºC) Frequency 580 kHz Equipment: • DW-UHF-6kW-III induction heating system equipped with a remote workhead with one 1.0 μF capacitor, and a 4-20 mA input controller to aid in voltage ramping. • An induction heating coil designed and developed specifically for this application. Process A unique helical coil consisting of four consecutive coils connected in parallel with a quartz tube lining is used to heat the wire to 650ºF (343.3ºC) for annealing. Results/Benefits Induction heating provides: • Higher productivity of 27' (8.2m) per minute • Reduction in surface oxidation & scaling • Consistent, repeatable results https://dw-inductionheater.com/induction-annealing-copper-wire.html?feed_id=253201&_unique_id=668c020c5b0d0
