Compositions characterized by an improved performance on:
• metal flowability in liquid phase
• increase of filling on complex shapes,
• optimization of scraps reusage without problems,
• minimization of solidification shrinkage.

Legor Group alloys for casting allow you to get the most from each type of casting system (traditional, in closed systems, with or without stones). Once correctly chosen the code depending on the type of machine and product to be obtained, simply follow the values given in the data sheets for best results.

The so-called all-purpose alloys are a good solution for those who have the need to use an alloy in both types of process, or do not want to multiply the number of alloys useful in a single colour and carat. Considering that these are alloys with low levels of deoxidizers, it is preferable to use all-purpose alloys in case productions are for the most part of mechanical processing and only in part of casting.

The variety of types of processes dedicated to the production of jewellery is made possible by the great intrinsic ductility and malleability of gold and silver alloys. It is up to the Research to provide solutions that push this characteristic to the limit, increasing the maximum levels of deformation and toughness, together with shininess, corrosion resistance, weldability.

Production of sheet: requires alloys that ensure high lustre and compact surface, combined with an excellent colour. The range goes from very soft alloys for the production of stamped items, to others with a certain stiffness for blanking. For the production of extremely thin sheets, age-hardenable alloys are recommended to improve processing and final quality of the piece.

Production of wire: the basis for the production of chainware. In addition to great flexibility and softness, excellent solderability is a key element. Other uses of this semi-finished product must ensure toughness and ductility, especially for productions in very thin diameters and minimum grain size to prevent the phenomenon of orange peel.

Hollow jewellery: production of tube by means of TIG welding, or for the production of hollow chainware, or production of tubes from continuous casting. The characteristic feature of these alloys is a great resistance to thermal and chemical treatments.
