Alumina Insulation Type SALI SALI has been serving 1700C low mass furnace users longer than any other alumina fiber board available today. SALI is a premium grade rigid fiber board with superior hot strength.
                                1700C (3092F)

AL-30AA Insulation

Alumina Insulation Type AL-25/1700 AL-25/1700 is a rigid medium duty grade of alumina fiber board. Not as strong as SALI but capable of delivering years of service.
                                 1700C (3092F)

AL-30AAH Insulation

Alumina Insulation Type AL-30AAH AL-30AAH was developed for use in copper vapor lasers where the ultimate in low mass alumina purity is required.
                                 1700C (3092F)

SALI

Alumina Insulation Type ZAL-45 & ZAL-45AAZAL-45 is an exceptionally strong low density alumina fiber product. Alumina bonded ZAL-45AA is useful in reducing conditions.
                          ZAL-45: 1650C (3002F)
                        ZAL-45AA: 1500C (2822F)

Alumina Insulation Type AL-30 & AL-30AA AL-30 and AL-30AA are rigid alumina fiber boards characterized by uniform open porosity and high machinability. Alumina bonded AL-30AA is used in fuel cell reformers.
                            AL-30: 1600C (3002F)
                          AL-30AA: 1500C (2822F)

AL-30AA Insulation

Alumina Insulation Type ECO-20AAECO-20AA is most commonly utilized as hotface insulation in furnaces with hydrogen rich atmospheres such as bright annealing furnaces.
                                    1600C (3002F)

Alumina Insulating Boards SALI-2

Alumina Insulation Type ZAL-15 & ZAL-15AAZAL-15 is a low thermal conductivity uniformly bound fiber board. It is ideal for machining into precision thermal insulators.
                            ZAL-15: 1550C (2822F)
                          ZAL-15AA: 1550C (2732F)

AL-30AAH Insulation

Alumina Insulation Type ALC & ALCAA ALC is the same material as ZAL-15 - but brings exceptional uniformity in an insulation material in cylindrical form.
                                ALC - 1550C (2822F)
                             ALCAA - 1550C (2732F)
