Rigid Alumina Products

ZIRCAR Ceramics Rigid Alumina Insulation products comprise a broad range of products available as boards, cylinders and custom shapes. Made of high purity raw materials these products bring significant utility to the high temperature applications they serve. A few features include:

Dimensional stability and superior hot strength to temperatures as high as 1825°C.
Low thermal conductivity
Uniform tightly bonded fine structures facilitate precision machining to tight tolerances.
Prefired, free of organics, NON RCF compositions.
Long life in severe refractory applications

	Alumina Insulation Type SALI-2 • SALI-2 is a premium grade rigid insulation board used as hotface insulation or a precision machined furnace fixtures. 1800°C (3272°F)
	Alumina Insulation Type SALI • SALI has been serving 1700°C 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. 1700°C (3092°F)
	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. 1700°C (3092°F)
	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. 1700°C (3092°F)
	Alumina Insulation Type ZAL-45 & ZAL-45AA • ZAL-45 is an exceptionally strong low density alumina fiber product. Alumina bonded ZAL-45AA is useful in reducing conditions. ZAL-45: 1650°C (3002°F) ZAL-45AA: 1500°C (2822°F)
	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: 1600°C (3002°F) AL-30AA: 1500°C (2822°F)
	Alumina Insulation Type ECO-20AA • ECO-20AA is most commonly utilized as hotface insulation in furnaces with hydrogen rich atmospheres such as bright annealing furnaces. 1600°C (3002°F)
	Alumina Insulation Type ZAL-15 & ZAL-15AA • ZAL-15 is a low thermal conductivity uniformly bound fiber board. It is ideal for machining into precision thermal insulators. ZAL-15: 1550°C (2822°F) ZAL-15AA: 1550°C (2732°F)
	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 - 1550°C (2822°F) ALCAA - 1550°C (2732°F)
