Application on Pre/post Welding Heat Treatment
95% Alumina for Ceramic Beads is manufactured by dry press method or injection way and is sintered at temperature up to 1650°C. The production is under careful material selection of high grade alumina spray drying granulation from what we call AL2O3, thus the stability is ensured. It enjoys high temperature resistance, excellent insulating property, and efficient thermal conductivity and heat transfer.
Application
As ceramic components of flexible pad and channel heaters at operations of pre and post welding heat treatment; Welding process, stress-relieving, pre-heating & post heating, ship-building, other resistance-heating environment.
Appearance: Pink or White. Other colors can be custom made on bulk quantity request.

Advantages
Compared with hot press method in the market, it proves higher density, better surface finish and better uniformity, and can be repeatedly used much longer. It enjoys excellent thermal conductivity and heat transfer, resistance against thermal shock and mechanical abuse.
Flexible Ceramic Pad Heater
Flexible Ceramic Pad (FCP) heater is manufactured by multi-strand quality 80/20 Ni-chrome heating wire through passages within interlocking ceramic beads, complete with two electrically insulated cam lock, which is protected from being heated by cold pure nickel wire that connects the heating wire. The alumina ceramic beads are made of sintered 95% Alumina Ceramics. It enjoys high temperature resistance, excellent insulating property, and efficient thermal conductivity, which provides FCP heaters with exceptional electrical insulating, and thermal shock resistance and thermal conductivity qualities.
FCP heaters are generally available to two standard volts: 80VAC, and 60VAC and using different connectors among different countries, one choice is Brass Cam lock Connector, the other choice is Welding Cable Plug (System DINSE).
