FONDERIA PECORA srl

The Alloy Used

The ability of Fonderia Pecora
to produce casts for a wide variety
of sectors, together with the
experience built up in casting
techniques, have enabled us
to increase the assortment of
non-ferrous alloys most commonly
transformed:

Aluminium-silicon alloys

Aluminium-magnesium alloys

Zinc alloys

Copper alloys

Die casting of aluminium alloys
The die casting of aluminium alloy casts accounts for the greater part of our production. In addition to primary and secondary aluminium-silicon alloys, suitable for the most common uses, we also process aluminium-magnesium alloys: the only ones capable of effectively supporting anodising treatment, for both aesthetic and corrosion resistance reasons.

Die casting of brass
Brass is undoubtedly the oldest of the materials used in die casting. It's the high copper content above all that makes this metal particularly suitable for the production of decorative casts, which can be polished to a mirror-like finish, chromium or nickel plated or subjected to bluing treatment. However, as a result of its excellent electricity conduction properties, its high resistance to corrosion and its good general mechanical characteristics, brass is also ideal for the production of casts for a wide range of industrial uses. It's a universal material, provided weight isn't a vital factor.

Die casting of zinc and its alloys
In spite of its excellent casting properties, zinc is mainly used in the production of one-off use anodes for nautical applications. And yet, in combination with aluminium it makes up one of the most widespread alloys in die casting: the zamak. This alloy's preferred for the production of low mechanical stress casts with complex geometrical characteristics, as it can be used to obtain very low thicknesses with limited ejection. In addition, the low cost and limited wear and tear on the moulds makes zinc-aluminium-magnesium alloy suitable for large series production. As the percentage of aluminium increases (>10%), this alloy takes on interesting mechanical characteristics and anti-friction properties similar to those of bronze.
