How to choose materials

How to choose the materials?

An essential step in the design process is the choice of material to use. In this page we can see how we can help Ashby maps for a quick and precise choice.

Density / Stiffness

The first map to consult is the one that allows us to understand which material is most suitable, understanding the need for lightness and rigidity of the product designed. In this map the model of young and density is related. From this table you can already understand which material may be most suitable for the design of the piece.


Mechanical resistance / Cost

At this point the second table that can be analyzed is the relationship between mechanical strength and the cost of the material, another essential factor to optimize costs.


Stiffness / Density

Once the class of material to be used has been identified, we must decide which member of this class is the most suitable. In the case of a metallic material we can analyze the following tables:



Conclusions on the choice of materials

By comparing the various tables we are able to select together with our customers what is the best material for the realization of the project, respecting the timing and requirements of the project.

The various maps allow us to have a targeted choice and also to quickly identify alternatives on materials.



Other Materials

Cast Iron

Cast iron is an iron-carbon alloy containing high percentages of carbon that can vary from 2.11% to 6.67%. Within this alloy can be found other elements such as: silicon, phosphorus, sulfur and manganese whose percentages vary according to different cases.

Aluminum and its alloys

Aluminum alloys can be classified as foundry alloys and as plastic processing alloys.

Other Services

Gear cutting

With over 30 years of consolidated experience in the field of mechanical machining and gearing, UFG srl mainly produces collaboration with designers in the initial phase of the project. Our production is designed for small and medium series or micro-ring sampling, with profile to ISO standards and special-purpose profiles.

Deep drilling

UFG provides deep drilling services on various materials such as steels, alloys and technopolymer. For years we have been offering this service to the chemical, medical, naval and oil industries and so on.


The mechanical sectors, in search of increasingly technological and cutting-edge solutions on the state of finishing surfaces and components, thanks to micro-sandblasting can face situations of simple cleaning and aesthetic finishing to more complex ones such as the deburring of mechanical components or controlled shot peening treatments such as anchorage, roughness and shot peening.
