Zhangzhou Zhenda New Material Co., Ltd., a leading global supplier of silicon metal, today announced the official launch of a new portfolio of advanced silicon metal products and integrated application solutions. Designed to address critical technical challenges in aluminum alloy casting, these innovations aim to help customers improve casting quality, optimize melting efficiency, and significantly reduce overall operating costs.
In aluminum alloy production, the purity and stability of silicon metal are key factors that determine both product performance and cost control. However, the industry has long faced persistent issues such as unstable melt fluidity, excessive slag and dross formation, inconsistent alloy composition, and accelerated wear of furnace linings — all of which limit production efficiency and casting consistency.
Drawing on a deep understanding of these pain points, Zhenda has developed a comprehensive, optimized approach that goes beyond the limitations of traditional material solutions.
“We understand that the challenges aluminum foundries face go far beyond what meets the eye,” said a spokesperson from Zhangzhou Zhenda New Material. “For example, even slight fluctuations in silicon metal purity can affect melt fluidity and lead to the formation of invisible micro-shrinkage pores within the casting — potential defects that compromise downstream processing and service life. Similarly, trace levels of reactive impurities in silicon can accumulate during melting, reducing melt cleanliness and altering slag wettability, which in turn increases metal loss.”
In response to these industry-wide challenges, Zhenda is offering the following key solutions:
1. High-Purity, Low-Impurity Silicon Metal
Zhenda supplies specified silicon grades, with tightly controlled levels of reactive impurities such as calcium, aluminum, and iron. This ensures cleaner melts, reduces slag and dross formation, and significantly enhances the quality and consistency of the final casting.
2. Outstanding Batch-to-Batch Consistency
Through a robust quality management system, Zhenda ensures high stability in chemical composition and physical properties across batches. This allows customers to maintain precise control over alloy compositions, minimizing production adjustments and scrap rates caused by raw material variability.
3. Customized Particle Size Options
To suit various melting processes and equipment configurations, Zhenda offers tailor-made silicon granule sizes, helping to optimize dissolution rate and alloying efficiency in molten aluminum.
4. Responsive Technical Support
Zhenda’s team of technical experts is readily available to provide professional support in areas such as melt process optimization, casting defect analysis, and silicon application guidance — ensuring stable and efficient operations for customers worldwide.
5. Stable and Cost-Effective Global Supply
Leveraging its self-owned production base and flexible CIF delivery terms, Zhenda guarantees stable, on-time, and competitively priced silicon metal supply to customers around the globe.
These solutions have already delivered significant benefits for international clients:
-
A Vietnamese aluminum foundry reported a 23% reduction in slag formation after switching to Zhenda’s low-calcium silicon metal.
-
A Korean alloy wheel manufacturer achieved markedly improved casting consistency and a 17% reduction in downtime.
-
A customer in the UAE noted a higher silicon recovery rate and a 1.5% decrease in overall melting cost.
Zhangzhou Zhenda New Material Co., Ltd. remains committed to driving quality and efficiency across the global aluminum casting industry through technological innovation and premium materials. We look forward to collaborating with partners worldwide to overcome challenges and achieve excellence — together.
