Replacing a Graphite Hot Zone with a Metal Hot Zone

Graphite hot zones are more durable, less expensive, lower maintenance and more energy efficient than their metal counterpart. Graphite is also more resilient against certain brazing processes. If your process doesn’t meet the above considerations for a metal hot zone, replacing it with a graphite one can save you time and money in the long-run.
