Primary Metallic Elements of Casting ZGCr24Ni7N Aluminum Melting Crucible |
||
| Element Symbol | Typical Content (wt.%) | Primary Function |
| Cr | 23.0 - 26.0% | Forms a dense chromium oxide layer for superior resistance to high-temperature oxidation and corrosion from molten aluminum. |
| Ni | 6.0 - 8.0% | Enhances high-temperature strength (creep resistance) and toughness, stabilizing the austenitic structure. |
| C | ≤ 0.35% | Strengthens the steel matrix. Content is precisely controlled to balance hardness and corrosion resistance. |
| N | 0.15 - 0.25% | Acts as a potent solid solution strengthener, improving strength and pitting corrosion resistance cost-effectively. |
| Si | ≤ 1.5% | Acts as a deoxidizer during melting and enhances scale resistance. |
| Mn | ≤ 1.5% | Improves hardenability and contributes to solid solution strengthening. |
| P | ≤ 0.04% | Impurity element. Strictly controlled to prevent grain boundary embrittlement. |
| S | ≤ 0.03% | Impurity element. Strictly controlled to prevent the formation of brittle sulfides that reduce toughness and fatigue life. |
| Fe | Balance | Base element of the alloy matrix. |

01
Exceptional Resistance to High-Temperature Oxidation & Corrosion
The high Chromium content (approx. 24%) forms a robust, self-regenerating chromium oxide layer on the crucible's surface.
This powerful shield provides outstanding defense against both atmospheric oxidation at extreme temperatures and the corrosive attack of molten aluminum, ensuring minimal scale formation and a purer melt.
02
Superior High-Temperature Strength and Deformation Resistance
Fortified with Nickel (approx. 7%) and Nitrogen, this crucible maintains remarkable structural integrity and creep resistance under heavy thermal and mechanical load.
It resists softening, warping, and bulging at operating temperatures, guaranteeing consistent performance and geometric stability throughout its long service life.
03
Outstanding Thermal Shock Resistance
Manufactured via precision casting, the crucible is designed to withstand the severe stress of rapid temperature cycling-from repeated heating and cooling cycles.
This superior resistance to thermal fatigue drastically reduces the risk of cracking and premature failure, ensuring reliable operation from the first heat to the last.
04
Extended Service Life and Superior Cost-Efficiency
By combining all the above properties, our ZGCr24Ni7N crucible delivers a significantly longer operational lifespan compared to conventional alternatives.
This durability translates directly into reduced downtime for changeovers, lower frequency of purchases, and a higher return on your investment, providing unparalleled long-term value for your operation.
Everything You Need to Know
What is the maximum safe operating temperature of this crucible?
The ZGCr24Ni7N material can safely withstand a maximum continuous operating temperature of 1100°C in an oxidizing atmosphere. This is significantly higher than the typical melting and working temperature range of aluminum and its alloys (700-900°C), providing a generous safety margin to effectively prevent crucible damage caused by occasional temperature fluctuations.
What dimensions and capacity specifications do you offer? Can they be customized?
We offer a range of standard dimensions and capacities (e.g., from 10kg to 500kg capacity) to meet the needs of various melting furnaces. Additionally, we provide professional customization services. You can share your furnace dimensions, required capacity, or specific drawings with us, and our engineering team will tailor the most suitable solution for you.
What is the approximate service life of this crucible?
Service life depends on several factors, including operating temperature, melting cycles, the type of aluminum alloy being melted, and maintenance practices. Under normal industrial operating conditions, our customers typically report a service life that is 3 to 5 times longer than that of ordinary crucibles. Proper preheating and avoiding sudden temperature changes can further extend its lifespan.
Is there room for a better price? Or do you offer bulk discounts?
Our pricing reflects the exceptional material costs and manufacturing processes, ultimately offering a lower Total Cost of Ownership. Yes, we highly value long-term partnerships and provide competitive discount schemes for large-volume purchases. Please let us know your estimated order quantity, and we will prepare a customized, preferential quotation for you.
