Pietro Galliani’s mission is helping companies solve their manufacturing needs through metal foils. Our core competence is understanding our clients’ technical requirements and developing foils and tapes that improve their products. This usually takes place in various steps.

1) Materials

We select the materials best suited to do the job. Our range of foils spans over 24 non-ferrous alloys. These metal foils can also be laminated with 13 kinds of polymers, for which we utilize 6 different glues according to the result we want to obtain. This range of materials offers endless possibilities of combination. Our laboratory allow us to measure and observe the grain structures of the metals we propose, a type of analysis that is fundamentally important when it comes to fine-tuning the most challenging metallurgical properties.

2) Dimensions

We set the dimensions of our foils according to the client’s demands and processing capabilities. We can reach thicknesses below 10 microns on the hardest non-ferrous metals, and we can slit our foils down to few millimeters of width. Our extremely narrow thickness tolerance ensures a very constant material performance, in addition to important savings for our clients by supplying them with the minimum amount of material needed.

3) Mechanical Properties

The materials and dimensions we establish determine the mechanical properties of the foil we are developing. This is why the next phase of our product-development process is the thorough testing of tensile strength, elongation, hardness and drawability. It is these properties that ultimately determine how our foils will behave on our clients’ machines, and that is why we make sure to understand well the amount of stress they can sustain without hindering performance.

4) Surface Analysis

Finally, we analyze the surface of our metal foils. Surface features such as roughness, wettability, amount of degreasing and lubrication, and anti-oxidation treatments for reactive alloys, all play an important role in the final performance of our materials. By providing data on these features we are able to understand, together with our customers, which surface characteristics should be increased and which avoided, something which is often a game-changer in many special applications.
