Recrystallized Alumina and Alumina Ceramics

Recrystallized Alumina Alsint 99,7 is an impervious material. It provides the basis for one of the most important technical oxide ceramic materials in the group. Alsint 99.7% Al2O3manufactured products have established themselves as the material of choice for a wide range of product types including Tubes, Rods, Crucibles, Thermocouple protection tubes, Insulators and machined components. With all products we have available such manufacturing techniques as Extrusion, Cast, Isostatically pressed and CNC machining.

Alumina or aluminium oxide leaves a low environmental impact on all kinds of aluminium products. Synthetic processes are used to produce aluminium oxide. We also offer a wide range of ceramic products. Alumina acts as an activation agent in high-quality chemical processing which is supervised by our trained professionals.

Most of our alumina products are produced by melting bauxite in an electric furnace. This method was introduced in the early 20th century, but these days several brands are extracting alumina through the Bayer process. We keep up to date with current marketing trends, allowing us to provide truly exceptional products.

Alumina Key Aspects:
  • Low conductivity
  • High Resistance to chemical corrosion
  • High mechanical strength and extreme rigidity
  • High melting point

Multi lab’s expert team focus on using the latest methods to produce high-quality alumina products. Aluminium is extracted into several varieties of tubes. It will be heated and pressed through several shaping tools to allow us to use it for other products. Aluminium is becoming more popular than copper for tubing in conditioners and many similar products. We can provide any type of aluminium products you need.

Alumina is widely used in ceramics, and we use it in our vast range of ceramic products. Multi-lab can provide technical alumina ceramics at reasonable prices. We always maintain efficiency in our quick services to produce high volume. Our broad range of products includes tubes, rods, crucibles, Thermocouple protection tubes, Insulators and various machined components.

Multi Lab has been leading the market for over 30 years. We take pride in being the number one choice for our clients. Continuous improvement and the dedication of our professionals is key to our growth. We work closely with our customers to create products that perfectly meet their requirements. Our professional team are available anytime. You can get in touch either by phone or by email and we will be happy to discuss your requirements with you.
