High quality materials for our pipes
Copper
Most of our products (tubes, connector pipes and bends) are made of copper.
We only use 99% pure copper, which is supplied to us in the form of coils or bars. The working range of the tubes goes from a minimum external diameter of 4 mm up to a maximum of 60 mm.
The copper we use is: CU-DHP (EN 12735-2 / EN 1057)
- Excellent mechanical characteristics, excellent heat conduction and resistance to severe pressures.
- Excellent cold and hot workability, excellent resistance to corrosion.
- Easily solderable.
- Hygienic, antibacterial material, combats the formation of pathogens for health and makes it ideal in drinking water systems.
- Pure material, which contains no additives that could contaminate drinking water.
- Visible usage, as copper, even if exposed to UV rays, sun, oxygen, temperature changes, does not age and does not change its properties over time.
- Recyclable endless times.
Steel
We manufacture products in steel and stainless steel.
Alloys based on iron and carbon, with the addition of other alloying materials such as nickel, molybdenum, silicon, titanium, etc.
The steels we use are: STEEL E235 + N (EN 10305-4)
INOX AISI 304 (EN 10217-7), INOX AISI 316 (EN 10217-7)
- Excellent mechanical and chemical characteristics
- Reliable in contact with dangerous substances such as gas
- Durable and resistant over time
- Excellent corrosion resistance
In particular, the steels are defined as rustproof due to the fact that, in the presence of an oxidizing environment (therefore also in contact with the air), a protective layer forms on their surface.
This invisible layer acts as a barrier to the continuation of oxidation and therefore corrosion.
Aluminum
It is a very ductile silver-colored metal, coming from bauxite minerals.
The aluminum we use is: ALUMINUM 3103-R H112
- Light but very resistant material, a fundamental characteristic for some of our products
- Used for pipes and manifolds in contact with water or chemicals and placed in particular environments. We exploit the peculiarity of having a good resistance to corrosion, (in fact it quickly develops an impenetrable oxide film on the surfaces)
- The high thermal conductivity makes aluminum very suitable for heating and cooling applications
- It is easy to work and to form as you wish
- Can be subjected to various surface treatments
- Recyclable endless times
Brass
Brass is an oxidizable alloy formed from copper and zinc.
It is a material with a high workability, used for its great antibacterial properties and high resistance to corrosion.
In recent years, requests by some customers to use lead-free brass led to the introduction of parts made with "green" materials.
The brass we use are:
CW617N-DW (EN 12164 - EN 12165 - EN 12420)
CW614N (EN 12164 - EN 12165 - EN 12420)
CW509L-DW (EN 12164 - EN 12165 - EN 12420) for lead-free products
CW510L-DW (EN 12164 - EN 12165 - EN 12420) for lead-free products
Cupronichel
Cupronickel is a copper alloy in which nickel is the main additional element. Mainly used in the naval sector.
The alloys we use are: CC300H (EN 1982)
They are characterized by an excellent resistance to corrosion, especially to sea water and are also appreciated for their high resistance to erosion.
The addition of other elements can give or improve a certain characteristic: iron increases mechanical resistance and at high flow velocities (impingement); manganese is used to deoxidise / desulfurize and improve workability; chromium can replace iron (up to 1%) and ensures higher mechanical strength; tin increases resistance to tarnishing (loss of gloss) and elasticity.
The presence of nickel increases the hardness and the breaking load, while maintaining the ductility close to that of copper.
This alloy is easily soldered by Tig welding.
