Noltina® syncarb z2e2 gives measurable savings through energy efficiency and durability

Syncarb Z2 e2


The metal casting industry is one of the most energy-intensive manufacturing sectors, with the melting process accounting for over half (55%) of its energy consumption. Although high energy expenses have been a significant concern of metal casters, the industry continues to use melting technology offering poor energy efficiency, often sacrificing energy efficiency for product longevity. In this manufacturing environment, where energy costs are driving innovation and productivity, crucible thermal performance is being tested every day.

With a goal of generating longer service life and increased energy savings, extensive lab and field testing was conducted on the new line of Syncarb Z2 crucibles. Through this research, Noltina® are proud to present the newest member of the Syncarb Z2 family, the Noltina® Syncarb Z2 e2 (Energy Efficiency) designed specifically for aluminium melting and holding applications. The results show an operational performance that meets and often surpasses its competitors “energy” crucibles in both reduced energy consumption and durability.

To summarise:

  • The Syncarb Z2 line is composed of iso-statically pressed, hybrid ceramic bonded crucibles with a high silicon carbide and graphite content.
  • The Syncarb Z2 line displays a higher breaking strength due to an improved granulation process. This means they are more resistant to damage and higher stress during operation and handling.
  • The Syncarb Z2 e2 displays higher thermal conductivity at all working temperatures, thereby offering increased savings for customers.


The Noltina product range uses a proprietary processing technology that results in a Syncarb Z2 product with a very homogenous and high density structure. The ceramic-bonded Syncarb Z2 e2 crucible was designed specifically to provide good chemical resistance against fluxes and excellent thermal conductivity in aluminium melting and holding applications. The inherent high mechanical strength allows the production of much larger crucibles. Other properties include outstanding oxidation resistance, high refractoriness and good thermal shock resistance. Other types of Syncarb Z2 crucibles are especially designed for use in zinc distillation applications as well as for melting and holding of copper and copper alloys.

The Noltina range of crucibles are stocked by Ramsell-Naber.
