Our alloys


The raw material used in the foundry is aluminium in its liquid form which, mixed with different elements (silicon, magnesium, copper, etc.) forms an aluminium alloy called "light alloy" in relation to their very low volumetric mass compared with base metals.

From ingots, the parts moulded by melting the aluminium are light and have many advantages for various industrial applications:

Possibility of having very high working temperatures,
Exceptional resistance to corrosion,
Lightweight,
Very good strength and hardness,
Good rigidity and good force/weight ratio,
Excellent properties of protection against electromagnetic interference,
Excellent thermal conductivity,
High electrical conductivity,
Good finishing characteristics,
Fully recyclable.
