With over 50 years of expertise, Jyoti Ceramic Industries is a leading name in the world of technical ceramics. Our dedication to innovation and quality has made us a trusted name in the industry, providing precise and excellent solutions for diverse needs.
At Jyoti Ceramic Industries, we offer a wide range of Alumina Oxide tubes and rods, ideal for manufacturing resistors. Known for their excellent properties, Alumina Oxide materials provide high electrical insulation, mechanical strength, chemical resistance, high thermal conductivity and uniform heat dissipation. These properties of ceramic allows the cores of these resistors to endure low to moderate power electrical current flowing through them without overheating and becoming damaged. Thus making them the top choice for technical ceramic components.
Duralox 92W is a ceramic composition made of 92-92.5% alumina oxide and a small amount of silica. This unique mix offers excellent electrical, mechanical, thermal, and chemical properties. Its high alumina content ensures superior durability and corrosion resistance.
Duralox 96W contains ≥96% alumina oxide with minimal silica. This ceramic composition is exceptionally pure, offering outstanding mechanical, electrical, thermal, and chemical properties. Its high alumina concentration ensures remarkable strength and wear resistance, making it ideal for demanding applications.
Efficiency is key at Jyoti Ceramic Industries. Our modern facilities allow us to quickly move from prototype development to high-volume production without compromising on quality. Our streamlined processes and stringent quality controls ensure every product meets the highest standards.
Our tubes and rods are carefully manufactured from special Alumina ceramic 92 and 96% compositions. Using advanced techniques like high-pressure extrusion and isostatic pressing, we ensure uniformity and precision in various sizes. Each component is then precisely machined and sintered at high temperatures to ensure best performance and durability.
Join our many satisfied clients who have experienced the Jyoti advantage. Whether you need custom solutions or standard components, trust Jyoti Ceramic Industries to deliver excellence every time.
