Foundry

In modern metallurgy and foundry technology, high-temperature raw materials of Georg H. Luh GmbH play an important role:

as a covering material and a carburising medium in foundry applications, graphite improves the end properties of the metal both in pure form and in combination with other raw materials.

Graphite and mica improve the structural characteristics as central components in moulding sands and facing materials and also act as separating agents.
