Natural silica sand "T5-F" for organic self-hardening molds.
While suppressing mold thermal expansion, it demonstrates sufficient refractoriness for the pouring temperature of cast iron!
"T5-F" is a natural clay sand for organic self-hardening molds, originating from Amagasaki, with a proven track record in cast iron casting. Due to its moderate SiO2 content, it suppresses mold thermal expansion that causes veining while providing sufficient refractoriness for the pouring temperature of cast iron. Additionally, it exhibits high mold strength in both the furan and alkaline phenolic self-hardening processes. 【Chemical Composition (Typical Values)】 ■SiO2: 92.16% ■Al2O3: 4.44% ■Fe2O3: 0.25% *For more details, please download the PDF or feel free to contact us.
