Premium 5kg Graphite Crucible with Ceramic Shield

Experience superior thermal performance and exceptional durability with our Premium 5kg Graphite Crucible. Engineered for professional metal casting, melting, and refining, this crucible combines the excellent heat conductivity of high-grade graphite with the structural integrity of a protective ceramic outer shell.

The dual-layer construction is designed to withstand extreme temperatures while maintaining its shape and preventing oxidation. The dense graphite interior ensures clean, uncontaminated melts for precious metals like gold, silver, copper, and aluminum, while the speckled ceramic exterior provides crucial insulation and protects the graphite from rapid degradation.

Key Features

• Dual-Layer Construction: High-purity graphite inner lining paired with a durable ceramic outer shell for maximum lifespan.
• 5kg Capacity: Perfectly sized for medium to large batch melting and casting projects.
• Flanged Top: Designed with a sturdy 11mm thick top flange for secure lifting and pouring using crucible tongs.
• Excellent Thermal Shock Resistance: Built to withstand rapid heating and cooling cycles without cracking.
• Clean Melts: The smooth graphite interior minimizes metal adhesion and prevents contamination of your alloys.

Precise Dimensions

We know that precision matters when fitting a crucible to your furnace. Please verify these measurements against your equipment:

Usage & Care Instructions

To maximize the lifespan of your crucible, always preheat it slowly to drive out any moisture before its first use. Store in a warm, dry place. Use properly fitted tongs that grip the body beneath the flange, never pinching the rim directly. Use a high-quality casting flux (like borax) to protect the graphite and your melt.

This works with various induction melters such as the Ultraflex, Galloni, Yasui, and other brands. Please double check dimensions to ensure an accurate fit before ordering.
