For investment casting excellence
LUX® is a family of master alloys specifically developed for jewellery production through the lost-wax investment casting process. Its formulations are engineered to ensure clean, defect-free castings with superior surface quality. Designed for precision and reliability, LUX® enables consistent results even in complex geometries and stone-in-place applications.
Clean casting, controlled results
LUX® is engineered to optimise the investment casting process by controlling metal behaviour during solidification. Its advanced deoxidation capability prevents unwanted reactions between molten metal and investment materials, reducing defects and improving surface integrity. The controlled viscosity of the alloy ensures a more stable and laminar metal flow, minimising turbulence and related casting defects. At the same time, the purity of raw materials eliminates issues such as hard spots, supporting consistent finishing and polishing. The result is a cleaner casting process, improved form filling and higher quality final components, even in demanding applications.
- Advanced deoxidation for clean and bright castings
- Reduced porosity and investment-related defects
- Excellent form-filling capacity for complex geometries
- Controlled metal flow to minimise turbulence
- Absence of hard spots for improved finishing quality
Frequently Asked Questions
Yes. LUX® is specifically designed to minimize oxidation and reduce loss during the casting process. Thanks to its optimized silicon-based technology, it forms a protective layer on the surface of the molten alloy that limits reactions with the investment material and reduces zinc evaporation. The result is cleaner castings, brighter surfaces and improved overall casting quality.
Yes. LUX® produces exceptionally clean and deoxidized castings, reducing oxide residues and surface contamination around the stones. This helps preserve the brilliance of the gemstones while minimizing cleaning and finishing operations after casting, making it an ideal solution for stone-in-place applications.
Yes. LUX® is engineered to improve metal flow and mold filling without relying solely on higher casting temperatures. Its optimized composition promotes smoother metal flow inside the investment mold while reducing oxidation and surface reactions. This helps achieve complete filling with cleaner surfaces and fewer casting defects
