Tin-titanium alloy sand is a specialized granular material composed of tin (Sn), titanium (Ti), and their alloys, engineered for unique industrial applications. Produced via smelting, atomization, or mechanical alloying, its particles vary in size from fine powders to coarse granules, offering tailored performance for specific needs.

In metal casting and welding, the sand’s heat resistance allows it to function as a mold filler or protective layer in high-temperature processes, ensuring dimensional stability. Additionally, its moderate hardness and malleability make it suitable for polishing and finishing applications in the marine and jewelry industries, where it enhances surface smoothness without scratching. Though niche, tin-titanium alloy sand addresses critical needs in precision engineering, hazardous environments, and high-tech manufacturing, balancing durability with gentle performance.
