ALUMINUM ALLOYS
plants and products for foundries
Production is carried out in a modern factory with sophisticated metallurgical treatment plants. The production process is taken care of in order to guarantee:
​
-
analytical constancy and repeatability;
-
H2 content at negligible levels;
-
absence of non-metallic impurities, such as oxides etc .;
-
crystalline structures suitable for transformation processes.
​
The plant used in the production process is carefully controlled and managed following the quality system standards which is composed of the following tools:
​
-
emission quantometer for analytical control;
-
weighing terminal for specific weight control;
-
instrument for checking radioactivity;
-
microscopes for micrographic and stereoscopic analysis;
-
weighing system for determining the apparent specific weight;
-
melting and holding furnaces;
-
fliter box with separate cycles for in-line degassing and filtering;
-
ingot molding machine for ingots weighing about 6-8 kg;
-
automated stacker and in-line weighing terminal.
THE PRODUCTION MIX INCLUDES ALLOYS:
-
primary Al-Si with limited Fe content (max 0.06% - max 0.10% - max 0.15 - max 0.20%) for the construction of wheels, steering wheels, motorcycle forks and other safety parts with excellent mechanical characteristics, as required by the most important car and motorcycle manufacturers;
​
-
Primary Al-Cu used for the creation of castings with good mechanical characteristics and workability of the tool (in particular for thermoforming molds)
​
-
Primary Al-Si-Cu-Mg used for general uses where good flowability of the alloy is required with good mechanical and workability characteristics of the tool;
​
-
Thermo-resistant primary Al-Si-Cu-Mg-Ni (eutectic and hypereutectic) for the construction of cylinders and pistons used by the most well-known manufacturers of cars, motorcycles and means of transport;
​
-
Al-Ni-Mn thermo-resistant primary used for the construction of gas burners in the household and non-domestic appliance sector;
​
-
Self-hardening primary Al-Si-Zn with low Fe and Cu content used in the most varied sectors, where the contribution of heat treatment becomes difficult;
​
-
Anticorrosive and anodizable primary Al-Mg with Mg from 3 to 10% used for the creation of castings for the nautical, food and furnishing sector;
​
-
