Special products

Aerospace

Valbruna, approved by the leading OEMs of the Aerospace and Defense industry, represents a reliable partner for the distribution of a several highly specialized Aeroval^® grades.

For Aerospace applications, like aeronautical engines, structural components, fasteners & rivets, fittings & sensors and many others, Valbruna offers a wide range of Specialty Alloys able to offer the greatest performance in environments subject to great fluctuations of temperature and extended cycle fatigue while guaranteeing absolute reliability, operational safety and efficiency.

Valbruna Ibérica is AS9120B certified for the distribution of stainless steel and nickel alloys in the Spanish aerospace and defense market.

Solenoid steels – Magival^®

Magival^® is a range of ferritic stainless steels dedicated to solenoid technology applications providing improved machinability and outstanding magnetic properties (high permeability and low coercive force). The carefully controlled chemical analysis and sophisticated working processes create a ferritic structure which is highly sensitive to variations in a magnetic field. This avoids the need for expensive heat treatment by the user after machining. Due to their extreme ease of magnetization and demagnetization, Magival^® grades are ideally suited for use in the manufacture of magnetic cores, solenoid valves, electromagnetic pumps and devices, flow regulators, fuel injection components, sensors, actuators etc.

Solenoid steels – Silicon iron alloys

Valbruna offers a range of Silicon-Iron alloys that are generally used in applications requiring higher electrical resistivity, higher permeability, and lower coercive force than provided by either carbon steels or soft magnetic stainless steels such as the Magival^® series.

Due to their high magnetic properties, Silicon-Iron alloys are mainly used in the manufacture of relays, solenoids and injectors parts for the automotive industry.

Valbruna grades of Silicon-Iron alloys are classified according to the silicon content in the chemical composition according to the standard classification of ASTM A867.

Special grades for flats & squares

We offer an extensive and versatile range of flat and square bars of Stainless and Specialty Steels, widely used for the manufacturing of valves, pumps, fittings, pharmaceutical & food machines, packaging machines, sensors and other industrial applications.

Heat resistant steels

There are some applications at elevated temperatures (such as aircraft components, chemical plants and petrochemical equipment) where a good combination of high strength and corrosion resistance is requested.

For these kinds of applications, the heat resistant steels could provide the most suitable compromise between different properties such as: good resistance to corrosion, creep, fatigue, thermal fatigue, thermal shock, impact, cavitation and erosion, good fracture properties, forming characteristics and weldability.

Threaded rods

Valbruna offers a wide range of Stainless steel threaded rods type A2 and A4, with metric threading according to ISO 3506 – 1, coarse thread, Form A – DIN 976, suitable for use in environments where corrosion resistance is a decisive factor for the end-use of the product.

The Stainless steel threaded rods are ideal for use in environments that are prone to condensation, contact with water, in carpentry, in civil and industrial construction, infrastructure, solar panel mountings, and in coating panels in environments prone to corrosion.

We supply products for special markets and applications: Valves, Pumps, Machined Parts,Forged Parts, Sensors, Vacuum, Nuclear, Energy, Oil & Gas, Cryo, High Pressure, Connectors, Bolts, Screws, Nuts, Loadcells, heat resistant, high corrosion resistant, etc.
