ZhenAn's high-purity Silicon Carbide (SiC) Grain (available in 90% and 88% grades) is a premium deoxidizer and
alloying agent specifically engineered for the precision casting and metallurgical industries. By providing a stable source of silicon and carbon, it ensures
superior melt quality and precise chemical control for
high-performance foundries.
Key Advantages of ZhenAn Silicon Carbide
- Superior Deoxidation Efficiency: Effectively removes dissolved oxygen from molten metal, preventing
gas porosity and improving melt fluidity
- Low Impurity Profile: Strictly monitored for trace elements like aluminum and sulfur,
ensuring integrity of complex castings
- Enhanced Nucleation: Acts as potent inoculant, promoting fine-grained structures and
improving mechanical properties
- Cost-Effective Performance: Provides stable recovery rate compared to traditional
ferrosilicon, reducing production costs
- ISO Certified Quality: Produced under rigorous ISO 9001:2015 standards, guaranteeing
batch-to-batch consistency

Frequently Asked Questions
What is the benefit of using SiC over Ferrosilicon?
SiC introduces both Silicon and Carbon simultaneously and reacts
exothermically, which helps maintain melt temperature and reduces
electricity costs.
Can I customize the grain size?
Yes, ZhenAn provides custom screening. Common sizes include 0-10mm,
1-5mm, and 200 mesh powder.
How does SiC affect the slag in my furnace?
It creates a more fluid slag, making it easier to remove and
protecting the furnace lining from premature erosion.
Is your material tested for moisture?
Absolutely. We ensure all grain is stored in dry environments and
tested for low moisture content to prevent hydrogen pickup in the
melt.
What is your minimum order quantity (MOQ)?
Our standard MOQ is 20-25 tons (one full container), but we can
discuss smaller trial orders for specific casting projects.
Do you provide third-party inspection?
Yes, we support SGS, BV, or any other third-party inspection
required by the client prior to shipping.
