High-Efficiency Metallurgical Silicon Carbide 88% (0-5mm) for Advanced Foundry Casting
This premium metallurgical silicon carbide is engineered specifically for foundry applications, delivering superior performance in deoxidizing and conditioning molten metals.
  • Stabilize Casting Quality: Significantly reduce porosity and gas defects in gray and ductile iron with superior deoxidizing power.
  • Optimize Melt Chemistry: Achieve precise Silicon and Carbon recovery simultaneously, eliminating the need for multiple expensive additives.
  • Superior 0-5mm Sizing: Engineered for rapid dissolution in induction furnaces and cupolas, ensuring 90%+ recovery rates.
  • Extend Refractory Life: Reduce FeO levels in slag to minimize chemical erosion of furnace linings and ladles.
  • Factory-Direct Reliability: Sourced directly from ZhenAn with consistent batch-to-batch chemical stability and ISO-certified quality control.
The Strategic Role of SiC 88% in Foundry Operations
In high-end foundry applications, the purity and grain size of silicon carbide are critical. The 0-5mm SiC 88% grade is specifically designed for metallurgical "conditioning." Unlike coarser lumps, this fine-to-medium granular distribution provides the perfect balance of surface area and density to penetrate the melt.
When added to the furnace, the silicon carbide reacts with metallic oxides, not only cleaning the metal but also releasing a significant amount of heat, assisting in temperature maintenance and reducing energy overhead.

Core Applications and Foundry Benefits
Inoculation and Nucleation
SiC 88% acts as a powerful long-term inoculant. It increases the number of eutectic cells and promotes a high "A-type" graphite flake count in gray iron, which is essential for pressure tightness and machinability.
Induction Furnace Charging
The 0-5mm sizing is ideal for "sandwich" charging in induction furnaces. By placing the SiC between layers of scrap, you maximize the contact time and ensure that the Carbon and Silicon are absorbed before the slag layer fully forms.
Slag Management
Foundries using SiC 88% report much "thinner" and more manageable slag. By reducing the iron oxide content, the slag becomes less sticky, making it easier to skim and reducing the risk of slag inclusions in the final casting.

Why Foundry Professionals Choose ZhenAn 0-5mm SiC
  • Zero Dust Loss: Our advanced screening process ensures that the 0-5mm range has minimal ultra-fine dust, preventing material loss through furnace extraction systems.
  • Enhanced Machinability: By promoting uniform graphite distribution, our SiC helps foundries produce castings that are easier to machine, reducing tool wear for the end customer.
  • Cost-Benefit Leadership: SiC 88% provides the most competitive "cost-per-point" of Silicon and Carbon for large-scale foundry operations compared to higher purity grades.
FAQ: Frequently Asked Questions
Why is 0-5mm the preferred size for foundry use?
The 0-5mm range provides an excellent blend of fine particles for immediate reaction and medium grains that survive long enough to deoxidize the entire melt volume. This ensures a consistent "inoculation" effect throughout the pouring process.
Can SiC 88% replace my current graphite recarburizer?
Yes, partially. While you may still need a dedicated recarburizer for final adjustments, SiC 88 provides a highly stable source of carbon (approx. 25-30% by weight) that is often more consistently absorbed than synthetic graphite.
Does using SiC 88% increase the risk of gas holes?
Actually, it does the opposite. By aggressively removing oxygen from the melt, SiC 88 reduces the potential for CO gas formation during solidification, which is a primary cause of pinholes and blowholes in castings.
How does Silicon Carbide improve the mechanical properties of iron?
By increasing the nucleation sites for graphite, it prevents the formation of massive iron carbides (cementite). This results in a tougher, more ductile iron with better tensile strength and vibration-damping properties.
What is the typical addition rate for gray iron?
Most foundries add between 0.5% and 1.2% by weight of the total charge. However, the exact amount depends on your scrap quality and the target Silicon/Carbon Equivalent (CE).
Is ZhenAn SiC 88% compliant with international standards?
Yes. Every shipment from ZhenAn is tested to meet international metallurgical standards. We provide Certificate of Analysis (COA) and can arrange for third-party testing (SGS/BV) to verify chemical and sizing specs before the material leaves our facility.
