Anderman Industrial Ceramics offer reaction sintered aluminium titanate, which is a material most commonly used in non-ferrous metal melting. It has also found applications in iron and steel, chemical and medical sectors.
The majority of our supply to date is aluminium titanate formed parts to non-Ferrous cast houses and foundries. The extraordinary properties of Alumina Titanate include high thermal shock resistance, low thermal conductivity and exceptional non-wettability to most Non-ferrous molten metal.
These properties are achieved by combining high purity alumina and titania in a precision controlled reaction sintering process. This enables us to engineer a micro-porous microstructure provides the benefits as seen in application including a longer service life and negates the need for any pre-heating as it is able to be exposed directly to molten metal.
Our valued customers have referenced our Alumina Titanate material offers them increased process reliability, reducing the risk of metal freeze-offs and Improving production yields when compared to alternative material options.
Other significant benefits in addition to increased service life are the non-contamination of the melt improving product quality and plant efficiency.
Dosing tubes up to 200mm in diameter and 590mm in length, riser tubes used in low pressure die casting, spouts, retainer rings, pouring nozzles, thimbles for billet casting as a technology advancement of historically used fused silica thimbles are all parts Anderman are regularly supplying.

FAQs
Frequent technical questions
Why does aluminium titanate work so well with molten aluminium?
It is non-wetting to molten aluminium, so the melt does not adhere or react with the part. Combined with very low thermal conductivity, this protects against freeze-offs and prevents melt contamination — the part stays clean and the metal stays where it should.
What replaces fused-silica thimbles in billet casting?
Aluminium titanate. It outlasts fused silica significantly, reduces inclusions in the billet and tolerates the same thermal cycling without the dimensional change historically seen as fused silica devitrifies. The technology shift is well underway across non-ferrous foundries.
Why doesn't it need preheating?
The reaction-sintered microporous microstructure has a very low apparent thermal expansion. A part can be plunged from ambient directly into molten aluminium without cracking — eliminating preheat ovens, shortening cycle time and reducing operator exposure to high-temperature handling.
