PRIMA range of products is the result of a long and deep research made in METALTECH InnovAction laboratories. This range of products specific for investment casting, thanks to the complex composition made of numerous different special elements, ensures an extreme level of deoxidation, an extreme surface quality, an enhanced fluidity and a long lasting of this features also after many reuses of casting scraps, making it the most advanced solution for castings with and without stones in place.PRIMA products have the capability to reduce the weight loss after investment casting, as well as keeping the original alloy color also after pickling, avoiding, so, problems of presence of different shades of colors in the same piece, in eventual presence of areas where the polishing results difficult like concave surfaces or stones pavè.

SPARK range of products are specifically studied for the production of objects obtained by investment casting. SPARK master alloys are indicated in the realization of castings with and without stones in place.The main feature of these products is the high resistance to oxidation and the maintenance of if also during the reuse of the scraps. Through deep specific researches in METALTECH InnovAction laboratories, the composition of SPARK products have been developed to give the highest surface quality, ensuring a substantial smoothness after casting and a consequent easiness of polishing, decreasing the working time spent for it.

DIVINA is a revolutionary range of master alloys for the production of nickel, palladium and manganese free white gold alloys. DIVINA product family comprehends master alloys for the production of objects obtained by investment casting. The main feature of DIVINA range is a very elevated grade of white and the total absence any element which can be could be dangerous for skin health. The casted pieces result with a high surface quality and very clean from oxides. This feature make the castings of objects with stone-in-place particularly clean and shiny under the stones. The extreme low casting temperature and low shrinkage of DIVINA, moreover, gives magnificent results in casting with stone-in-place in the integrity of the stones color and resistance to cracking. The gold alloys obtained with DIVINA master alloys completely respect the UNI EN 1811 regulation in all the fineness’.
