Forging of aluminum
We perform closed die forging of aluminium and alloys from the 5xxx, 6xxx and 7xxx series, including AlMgSi1 (6082, 6061), AlZnMgCu1.5 (7075) and AlMg3 and AlMg4.5Mn0.7. We forge parts from 0.05 to 6 kg and control temperature and deformation rate with high precision in order to preserve natural ductility of aluminium and reach 20–30 percent higher mechanical strength compared with casting or extrusion.
Our aluminium program targets
-
Electrical and energy industry (high voltage connectors, electric motors, transfer components)
-
Shading and mounting systems (profiles, brackets, aluminium mechanical joints)
-
Agricultural and agro machinery
-
Mechanical engineering and technical structures
-
Niche mobility and e projects (rally, e motors, e-bikes and other specialized components)
For aluminium forging we use a CNC screw press rated at 1000 t, which gives full control of speed, force and temperature. Each year we process roughly 200 tons of aluminium, which secures extremely short lead times and high repeatability of quality.

ALUMINIUM FORGING (5 facts)
Aluminium 6082 – alloy of balance
Aluminium 6082 (AlMgSi1) from the 6xxx series is the most common alloy for machining after forging. It offers good strength, low weight and excellent corrosion resistance, so it suits energy systems, lifting mechanisms and architectural structures.
Aluminium 7075-T6 – strength lighter than steel
Alloy 7075-T6 reaches tensile strength up to 570 MPa, higher than many structural steels and at one third of the mass. It is used in aerospace, sports and e mobility industries where every gram matters.
Aluminium 5xxx – elasticity and corrosion stability
Alloys from the 5xxx series (AlMg3, AlMg4.5Mn0.7) are known for excellent resistance to marine corrosion and good formability. They are used for marine components, outdoor structures and mechanical elements where a mix of elasticity and durability is required.
CNC screw press 1000 T – precision under pressure
Our 1000 T CNC screw press provides full control of force and temperature. Each blow is electronically regulated and reaches accuracy of ±0.2 mm. This is a key advantage for aluminium, which starts to deform already at around 500 °C.
Difference in forging energy – steel versus aluminium
Forging aluminium requires roughly three times less energy than steel, while the process is about three times more sensitive to temperature fluctuations. For this reason we control every blow digitally so aluminium keeps a perfect structure without micro cracks.
Frequently asked questions about aluminium forging
Why is forging aluminium more demanding than forging steel? Aluminium shows higher ductility and higher sensitivity to overheating, so the process requires precise control from temperature to deformation rate.
Where are forged aluminium parts used?
Most often in electrical industry, light structures, e-mobility and equipment where low weight, strength and precision play a key role.
Is forged aluminium suitable for surface treatment?
Yes, the surface after forging is smooth and suitable for anodizing, powder coating or KTL protection.
