Filter Application
After using our ceramic foam filters for magnesium alloy filtration, customers have seen a reduction in internal porosity and inclusion defects in magnesium alloy castings, resulting in lower foundry scrap rates and direct savings in production costs. After filtration, the tensile strength of magnesium alloy castings increased by 15-20%, while ductility also improved. With less rework and post-processing, production cycle times are shortened and productivity is increased.
Frequently Asked Questions
What are the advantages of magnesia ceramic foam filters compared to other filter materials?
The primary advantage of magnesia ceramic foam filters is their excellent chemical compatibility with magnesium alloy melts. Traditional alumina or silicon carbide filters may react in high-temperature magnesium liquid environments, resulting in reduced filtration effectiveness or contamination of the liquid metal. Our product is made of 99% high-purity magnesium oxide, which remains chemically stable at magnesium alloy casting temperatures and does not react with the melt. Furthermore, its three-dimensional network structure provides deep filtration capabilities, achieving filtration efficiencies exceeding 95%, far exceeding the 60-70% of traditional metal mesh filters.
How to Choose a PPI?
The following factors should be considered when selecting the appropriate pore density:
- Inclusion Size: Generally speaking, smaller inclusions require a higher pore density.
- Metal Flow Rate: At higher flow rates, a lower PPI is recommended to reduce resistance.
- Casting Quality Requirements: High-precision castings typically require a 50-60 PPI, while general castings can require a 30-40 PPI.
- Alloy Type: Different magnesium alloys may have specific requirements.
Can magnesia ceramic foam filters be reused?
Our magnesia ceramic foam filters are designed for single use. After a single use, the filter may have trapped a significant amount of inclusions, partially blocking the pores and significantly reducing filtration efficiency. Furthermore, the filter may have undergone trace reactions with the melt, potentially compromising its structural stability. For quality control and safety reasons, we strongly recommend using a new filter for each pour to ensure optimal filtration and casting quality.
Can you provide custom specifications? What is the custom process?
Yes, we specialize in providing customized products. The customization process is as follows:
