Product Description

Graphite Casting Crucible and Stopper for Yasui K2/KT17
We adopt special high-purity, high-strength, and high-density graphite materials. The selected specialized material can make our graphite crucible more durable than graphite products made in ordinary material, with a longer service life and can bear high temperature 2000 ºC. The graphite crucible adopts high-precision CNC machining equipments, which can provide customers with high-performance graphite melting crucibles, casting crucibles, graphite ingot molds, tube pulling, rod pulling and plate pulling molds, etc.

6 reasons to use our graphite crucibles and stoppers:
High Purity
High Density
Good Acid and Alkali Resistance
High Temperature Resistance
High Strength
Longer working life

Product Features:
1. Thermal stability: Specially designed for the use conditions of graphite crucibles for rapid heating and cooling to ensure the reliability of product quality.
2. Corrosion resistance: The uniform and fine substrate design delays the corrosion of the crucible.
3. Impact resistance: graphite crucible can withstand extremely high thermal shock strength, so any process treatment can be carried out with confidence.

4. Acid resistance: The addition of special materials significantly improves the quality of the crucible, performs excellently in acid resistance indicators, and greatly extends the service life of the graphite crucible.

5. High thermal conductivity: The high content of fixed carbon ensures good thermal conductivity, shortens dissolution time, and significantly reduces energy consumption.

6. Control of metal pollution: Strict control of material composition ensures that the graphite crucible does not contaminate the metal during melting.
