Made by JISPLHigh alumina bricks manufacturer and supplier
High alumina refractory bricks from about 45% up to 85% Al₂O₃ for the hottest and harshest zones, made in our own units.
About high alumina bricks
High alumina bricks contain more alumina than fireclay bricks. That brings higher refractoriness, better strength at temperature and better resistance to slag, chemical attack and abrasion. We manufacture high alumina bricks in a range of grades, so each zone of your lining gets the brick it needs instead of over-specifying the whole lining.

Common questions
Which alumina grade do I need?
It depends on temperature, slag and abrasion in each zone. Higher grades cost more, so we usually recommend them only where conditions are harshest. Read our guide on fire bricks vs high alumina bricks.
Do you supply mortar with the bricks?
Yes, matching high alumina mortar can be supplied with the bricks.
Do you share technical data sheets?
Yes. Detailed data sheets with grades and properties are shared on request. Use the WhatsApp or email buttons on this page.
Do you provide test certificates?
Yes, a material test certificate comes with every consignment.
Do you supply outside Rajasthan and export?
Yes. We supply across India from Bhilwara and our offices in Jaipur, Wankaner and Ahmedabad, and we also export.
