There’s not much that we don’t know about cast aluminium.
HAI has two of the most modern and flexible foundries in Europe which achieve extremely high annual production rates. At our sites in Ranshofen (Austria) and Santana (Romania) 220,000 tonnes of wrought and cast alloys is produced every year – in the form of cast round billets and rolling slabs, or as two-piece ingots. The latest technology is employed: from the two-chamber melting furnace to the hearth furnace with electromagnetic stirrer and the tiltable rotary furnace.
ASI Performance Standard certification
HAI has achieved Aluminium Stewardship Initiative (ASI) Performance Standard certification for its CASTING operations at the Ranshofen and Santana sites.
“In view of our strong motivation to continually improve our business processes and make them sustainable, we are very proud to now be accepted into the ASI community. We focus intentionally on the continuous development of sustainable production processes. In doing so, we are complying with our commitments to ethical and social aspects as well as to the environment.”

Certification by TÜV Rheinland Cert GmbH
TÜV Rheinland Cert GmbH is an independent auditor which has carried out an audit of the HAI foundries in Ranshofen and Santana. 59 criteria within the three pillars of sustainability:
- Corporate management
- Social issues
Between them our two foundries at Ranshofen (Austria) and Santana (Romania) have an annual capacity of roughly 220,000 tonnes. They are used for the reliable and on-time production of the following range of products:
Extrusion billets are exclusively cast by using the “Wagstaff AirSlip ingot moulds” and are available in all standard sizes.
are exclusively cast by using the “Wagstaff LHC ingot moulds”.
can be supplied in various designs which are made of various cast alloys.
2.0 to 2.5 MT sows, also reprocessing of dross or swarf on request.
HAI provides the whole range of wrought and special alloys, e.g. crash-resistant and gloss alloys.
short and long scrap, clean and contaminated scrap (such as painted profiles, oily swarf etc.)
Our two foundries at Ranshofen (Austria) and Santana (Romania) provide the highest technological standards: three modern two-chamber melting furnaces, a hearth furnace with electromagnetic stirrer, and a tiltable rotary furnace. What’s more, we use state-of-the-art technologies and procedures in order to produce top-quality products in an environmentally friendly manner:
Alpur, SNIF, STAS to reduce hydrogen and impurities
Ceramic filters are used to remove even the finest oxides
Wagstaff AirSlip moulds
The “Wagstaff AirSlip” technology allows casting with thin edge zones <0.3 mm (300 µm). Higher extrusion speeds and surface standards can therefore be implemented for high-end applications.
Wagstaff LHC moulds
These allow very thin edge zones, so there is much less need for further processing.
100% full-body ultrasonic inspection is carried out. This is used to examine ingots and billets for inclusions as well as core and surface cracks in accordance with the requirements of the ASTM B594-09 standard (Class A B & C).
Batch and continuous-pass homogenisation with cooling rates of up to 800 K/h.
