Lead-free materials suitable for plumbing components applicable to water supply devices and plumbing facility equipment parts!
We offer lead-free "environmental materials for plumbing parts." "Biwalite," which is ideal for large water meter bodies through sand casting, does not use expensive and rare chemicals (Bi or Se), resulting in minimal cost increases. Additionally, it has a low occurrence of shrinkage cavities and good fluidity in casting. We also have materials such as "Ecobras," which excels in machinability, and "Cricabronze," which has almost no lead leaching and is suitable for various components of water supply devices and plumbing facilities. 【Features (Biwalite)】 - Does not use expensive and rare chemicals (Bi or Se), resulting in minimal cost increases - Low occurrence of shrinkage cavities and good fluidity in casting - Can accommodate required strength and elongation by adjusting the amount and ratio of chemical components - Easy to cast with good yield - Recyclable and can be remelted *You can also view our e-commerce site from the link below. *For more details, please refer to the PDF document or feel free to contact us.
