Aluminum and Copper Rectifiers on Large Case 6G Series Alternators

We now offer two different styles of heavy duty bridge rectifier for our 6G series large case alternators.

Copper Rectifier

Pros

  • Higher thermal mass
  • Better electrical and thermal conductivity

Cons

  • Doesn’t dissipate heat to air as well (.65 emissivity coefficient)
  • 8x 70A diodes
