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
