Wide Range Of Use: Graphite molds are commonly used in experiments and metal smelting, suitable for smelting alloy tool steel and smelting non ferrous metals and alloys. 5. Portable Design: Light weight and in small size, easy to store and carry, suitable for metallurgy, foundry, machinery, chemical industry and other industrial sectors. Specification: Item Type: Graphite Mold Material: Graphite Shape: Rectangle External Size: Approx. 42 x 22 x 10mm / 1.7 x 0.9 x 0.4in Internal Size: Approx. 35 x 15 x 5.5mm / 1.4 x 0.6 x 0.2in Introduction: The graphite crucible melting material is crystalline graphite. Therefore, the original graphite with various physical and chemical properties is retained. Using special high purity graphite materials, high strength, high density graphite materials; can provide excellent performance of graphite crucible smelting, casting crucible, graphite groove, mold and other graphite products. The selection of special special materials can make our graphite crucible products more durable than ordinary materials, with longer service life and better resistance to high temperatures above 2000℃.. Package List: 1 x Graphite Crucible Note: Please allow slight error due to manual measurement. Thanks for your understanding.
