Metal Melting Crucible

Material Composition and Key Properties

Our Metal Melting Crucibles are made from a premium blend of graphite and silicon carbide (SiC), materials chosen for their excellent thermal conductivity, mechanical strength, and resistance to corrosion.

• Graphite-Silicon Carbide Composition: This combination ensures the crucibles can withstand extreme temperatures while maintaining structural integrity, making them perfect for melting a wide range of non-ferrous metals.
• High Thermal Conductivity: The thermal conductivity of graphite allows for efficient heat transfer, resulting in faster melting times and uniform heat distribution, crucial for achieving consistent metal quality.
• Resistance to Thermal Shock: Our crucibles offer outstanding resistance to thermal shock, meaning they can endure rapid temperature changes without cracking or warping, making them ideal for high-intensity metal casting processes.

High-Temperature Capabilities

Non-ferrous metals often require high temperatures to melt properly. Our crucibles are designed to handle temperatures up to 1600°C, making them suitable for a wide range of melting operations.

• Operating Temperature Range: These crucibles can melt metals like aluminium (660°C), copper (1085°C), and zinc (419°C) while maintaining consistent performance even at extreme temperatures.
• Longevity in High-Temperature Environments: The use of silicon carbide ensures that the crucible remains durable over multiple melting cycles, reducing the need for frequent replacements and keeping operational costs low.

Chemical Stability and Corrosion Resistance

In the smelting of non-ferrous metals, the crucible must be able to resist corrosion and chemical reactions with the molten material. Our Metal Melting Crucibles are designed with this in mind, offering excellent chemical stability and non-reactivity.

• Non-Reactive to Molten Metals: The crucible’s graphite and SiC composition prevents unwanted reactions with molten metals, ensuring that the final product remains free from contaminants.
• Corrosion Resistance: These crucibles resist oxidation and corrosion, which can occur when exposed to the aggressive environments of molten metals, thus extending the life of the crucible and maintaining metal purity.

Applications in the Non-Ferrous Metal Casting Industry

Our Metal Melting Crucibles are versatile and can be used in various applications within the non-ferrous metal casting industry:

• Aluminium Casting: Suitable for melting and casting aluminium and its alloys, ensuring high-quality molten metal for casting components.
• Copper and Bronze Casting: Perfect for use in copper, bronze, and brass melting operations, ensuring consistent and precisely controlled melts.
• Precious Metal Casting: These crucibles are widely used in melting gold, silver, and platinum, offering smooth, contamination-free melts, critical for high-value metal casting.
• Zinc Casting: Highly effective in the melting of zinc and its alloys, particularly for die casting applications in the automotive and electronics industries.

Benefits for Metal Casting Professionals

• Faster Melting Cycles: The superior thermal conductivity of our crucibles ensures that metals melt faster, allowing for increased production efficiency.
• Long Service Life: Our crucibles’ thermal shock resistance and corrosion resistance lead to longer lifespans, reducing downtime and costs associated with frequent replacements.
• Improved Metal Quality: The non-reactive materials and smooth interior surfaces of the crucibles prevent metal adhesion and contamination, ensuring high-purity molten metal ready for casting.
• Energy Efficiency: The high heat retention properties of graphite and silicon carbide reduce the energy required to maintain molten metal, leading to lower energy consumption in large-scale operations.
