ENBO ™

A HIGH HARDNESS, ELECTROLESS NICKEL - BORON ALLOY PLATING PROCESS

The ENBO system is a bright electroless nickel - boron alloy process designed to deposit a uniform, nickel - boron alloy onto a great variety of metals, alloys, and non-conductors.

  • The ENBO system is available in convenient packaging where ENBO A and ENBO B are used for bath make-up, and ENBO R and ENBO Z are used for replenishment.

Some advantages of the ENBO system are:

  1. High as-plated hardness
  2. Low bath operating temperature
  3. Low electrical resistivity

The ENBO system electroless nickel processes meets or exceeds AMS 2399
