New Protection For YOUR EquipmentAt Temperatures Up To 3300 F ALUNDUM1" costobles offer unusual advontoges to oil industries using high temperature installations
The new Norton ALUNDTJM Castables are made in two types: 33-1 Insulating and 33-HD Heavy Duty. At t e m p e r a t u r e s up to 3300°F both types have been extremely successful in protecting high temperature processing — in many industries and many different installations. ALUNDUM 33-1 Insulating Castable is made up primarily of pure aluminum oxide bubbles, tiny and countless. Forming a network of air spaces, it assures excellent insulation, even at highest commercial temperatures. ALUNDUM 33-HD Heavy Duty

Castable is chiefly composed of dense grains of pure aluminum oxide. It is recommended for forming dense monolithic surfaces in many types of furnaces where high temperature conditions are particularly severe. Both 33-1 and 33-HD Castables are very easy to store, mix and use. With them you can cast simple or complex shapes quickly and economically, replace more expensive pre-fired shapes, and cut maintenance and replacement costs to very lowest.
