Induction Annealing Copper Wire

Induction Annealing Copper Wire

Objective:ย Induction Annealing a brazing copperย wireย for preform production.

Material: Copper Nickel Silver 2774 Alloy rod 0.070″ (1.8mm) diameter.

Temperature 650ยบF(343.3ยบC)

Frequency 580 kHz

Equipment: โ€ขย DW-UHF-6kW-III induction heating systemย equipped with a remote workhead with one 1.0 ฮผF capacitor, and a 4-20 mA input controller to aid in voltage ramping. โ€ข Anย induction heating coilย 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 650ยบF (343.3ยบC) for annealing.

Results/Benefitsย Induction heatingย provides: โ€ข Higher productivity of 27′ (8.2m) per minute โ€ข Reduction in surface oxidation & scaling โ€ข Consistent, repeatable results
