More than just a curve, it means analysing the request in all its aspects starting with the functionality of the component in order to outline the appropriate production cycle. Depending on the specific needs related to the use and utilisation of the part required, we build a production process together with the customer to ensure good product quality.
Going into more detail, the chemical-physical properties of the various main alloys, defined according to ASTM nomenclature, should be considered in order to understand the specific characteristics and consequent use in the various product sectors.
There is a second classification to indicate the degree of purity of each alloy.
Grade 1Commercially defined as pure. Excellent ductility at the expense of low tensile strength. Very good corrosion resistance.
Grade 2also defined as commercially pure, but has a higher percentage of oxygen. It is a very popular alloy due to its good ductility, good mechanical strength and excellent corrosion resistance. It is found in all forms, tube, round, sheet.
Grade 5 (Ti6Al4V): Used mainly in the aerospace, motorsport and marine sectors. High tensile strength, high corrosion resistance but is less ductile than the 2 previous alloys. It is mainly used for machining from solid and for the manufacture of mechanical and structural components.
Grade 9 (Ti3Al2.5V): It has very similar characteristics to Grade 5 but is mainly used for the production of pipes. It is therefore widely used in the motorsport sector. Unlike the grade 2 alloy, which is also available in tubular form, it has better mechanical properties at the expense, however, of a lower elongation percentage. The application sectors and construction technologies between one alloy and the other are therefore different.
It is quite common to make the mistake of generalising under the term aluminium what are in fact alloys composed of various elements; most commonly classified by a numerical code, they range from alloys 1000 (Al 99%) up to alloys 9000, and according to their chemical composition they have certain physical characteristics.
Common among the main characteristics are low density, high thermal and electrical conductivity, high ductility and a low melting point.
The most commonly used alloys are alloys 6000 (Al Si Mg), also called anticorodal.
Alloys 2000 (Al Cu): they require solution heat treatment, hardening and ageing to develop the mechanical values for use; after this treatment they develop mechanical properties comparable to those of carbon steels. They are used for parts and structures requiring high strength-to-weight ratios. They have excellent machinability but limited fusion weldability.
Alloys 5000 (Al Mg): These are alloys of great commercial interest, they increase their mechanical properties by work hardening, i.e. by cold deformation. They are widely used in the production of tanks.
Alloys 6000 (Al Si Mg): excellent weldability and ductility. Although they can be heat-treated for hardening, they do not reach the mechanical properties of alloys 2000 (Al Cu) and 7000 (Al Zn Mg).
Alloys 7000 (Al Zn Mg): Excellent mechanical strength at the expense of lower ductility. They are commonly used where high mechanical strength and fatigue resistance is required. They have good machinability on machine tools and, in most cases, poor fusion weldability. Widely used in the aeronautical, automotive and motorsport sectors, more generally they are used for the construction of parts subject to stress.
Nickel alloys are widely used in the motorsport, automotive, shipbuilding and petrochemical industries; mainly due to their excellent resistance to oxidation at high temperatures and corrosion.
They are mainly used for exhaust systems, gas turbines and pipelines for transporting corrosive fluids.
Nickel alloys do not belong to the family of light alloys as they all have a high specific weight and have in common that they are difficult to machine.
The most commonly used alloys are:
Inconel 600:
It has good tensile strength and oxidation resistance at high temperatures, up to 1093°C. It is not suitable for use in the presence of sulphur.
Inconel 625:
Compared to the previous alloy, it has a lower nickel content but the alloy composition increases corrosion resistance. It has excellent weldability and good cold workability. This is why it is often used in the automotive industry for exhaust systems, gas turbines and in the petrochemical industry.
Inconel 718:
It has excellent tensile strength and good corrosion resistance. Like alloy 625, it has good weldability and good cold workability.

We realise projects from the development and 3D CAD design to the construction of the first sample or small production series.
We are able to build welded assemblies with any type of weldable material and CNC machined components.
