Master Alloy Product Lines


Product lines are as under :-

1) Master alloy line :-
Alloys are produced in drops engineered to vast range of compositoins , solutions for various titles of gold and silver

2) Silver line :-
A large choice of product in drops both in tilte or master alloy conceived to satisfy all the needs of high qualtiy silver production form optimium resistance in tarnishing ,maximising productivity and workability.

3) Solder alloys :- These are available in drops, powders, paste, liquids and semi-processed wire. This range of alloys are very different in nature in comparison to other alloys. These alloys provides the soldering solution along with high performance and compatibility of use.

4) Ready to use Precious alloys line :-

Dental Alloy


We are offering a wide range of Alloys for Dental Products. These alloys are known for their high-quality and purity that makes it widely demanded in major markets of the world. The most common question would be the durability of the product. Eterna is Legor Group’s answer to the need for innovation expressed through the information gathered from the dental sector and many dental technicians studios, with which our internal Research and Development laboratory has been working for several years. We use high quality raw material and skills to enhance the quality of these products.

Eterna Line:-

Eterna is the first line of high-purity dental alloys: all of the metals employed in the various formulas come from certified suppliers and undergo rigorous quality controls upon acceptance, while our innovative fusion technologies and processing ensure maximum homogeneity; all of these factors guarantee that the production process can be perfectly replicated. Every alloy produced is therefore inspected, analyzed and assigned a lot number, making it traceable even over the long term.

Eterna is a new dimension of work for dental technicians, who can choose from the various families that make up the line:

- ETERNA P alloys for ceramics
- ETERNA C alloys for resin
- ETERNA U universal alloys
- ETERNA S solders for precious alloys
- ETERNA N low Chrome/Cobalt alloys and the relative solders

Alloys are in granules with difference percentage variations.
