About Spangle
Master Alloys for
Jewellery Manufacturing
Consistent. Predictable. Built for real production conditions.
Who We Are
Built for predictable manufacturing outcomes
Jewellery manufacturing depends on consistency — across melts, batches, operators, and timelines. Small variations at the alloy stage often show up later as rework, finishing delays, or inconsistent output.
SPANGLE master alloys are developed with a focus on reliable performance under real jewellery manufacturing conditions, helping reduce variation and support repeatable results in everyday production.
Formerly operating under our legacy name, we are now Spangle Alloys Private Limited — a formal step that reflects our growth and commitment to the jewellery manufacturing industry.
