Precision mechanics processes metals in order to transform them into finished products, whether they are individual parts or machine components. These parts must be worked with a high level of precision to suit their specific function and correspond to the machine or system in which they are to be mounted.

Many different raw materials can be used in precision mechanics to create the required final parts. Below we list 7 of the most common raw materials used in precision mechanics processes.


Stainless steel is a raw material used for precision mechanics due to its strength and corrosion resistance. Stainless steel is a very versatile material, ideal for many applications.

Stainless steel is made of an alloy of iron and chromium that binds to oxygen particles forming solid chromium oxide on the surface of the steel.

This material is mainly is used to produce aerospace and automotive components, medical devices and equipment for industry.



Aluminum has many advantages: it is lightweight, easy to work, non-magnetic, corrosion resistant and cheap.

In some industries, aluminum is becoming a preferred choice over steel, however, to achieve the best results, aluminum welding must always be handled by a very experienced company.

In addition to the advantages already listed, aluminum can be processed more easily than other metals and can be plated with many different materials to make it harder or more conductive as a cheaper alternative to steel, stainless steel or copper.

Aluminium also responds very well to cutting, drilling, punching and milling operations.

Aluminium is used to produce machine parts, telephones, filters and tubes.

  1. BRASS

Brass, an alloy composed of zinc and copper, is a cheap material. The advantages of brass processing are the ease of processing, smooth and clean finish, non-sparking, tolerances and threads. Brass also has a low melting point and low magnetism, which makes it excellent for use in various industries.

Brass should not be used in semiconductor products or vacuum applications because of the zinc and tin in the material.

Mostly, stainless steel is used to produce handles, valves, bearings and components for the marine industry.



Titanium is a very appreciated metal and very useful for mechanical processing. Titanium is very resistant to heat and corrosion and has the most significant strength to weight ratio of any metal.

It is also lighter in weight, inert and biocompatible, all characteristics that make it suitable for a wide range of applications, from aviation to medical instruments.

However, one of the disadvantages of titanium is that it can be quite difficult to work with and has a high price.


  1. STEEL

Steel is one of the most popular metals and is valued for its strength and durability and is easier to weld than other common materials.

Steel is generally used in industrial applications, in car production and in the oil and gas industry.

Steel can be subject to corrosion without heat treatment of plating.

In all the metals composed of iron and coal, in addition to small amounts of other elements such as sulfur, phosphorus, silicon and manganese, there is steel, ideal in many applications.

There are different types of steel, depending on the amount of carbon and iron present. Steel is usually divided into five main categories: alloy steel, tool steel, carbon steel, stainless steel and high strength low alloy steel.



Copper, a natural metal, is highly valued for precision mechanics because it offers many advantages such as versatility, durability, electrical conductivity and natural corrosion resistance.

Thanks to its extreme versatility, copper is suitable for different types of processing and for the production of a wide variety of end products such as radiators and generators, tools, pots and heat exchangers.





Plastic can be used as a raw material because it is cheap, non-metallic and non-conductive. Because plastics are inert and can be modified to fit a wide range of different properties, plastic machined parts are used in a geat variety of industries, including medical, electronic, industrial and scientific applications.



Using a wide range of different raw materials, precision mechanics companies are able to provide a variety of parts to suit every application and system.
