The correct material for each area of application.
There is a wide range of aluminium alloys that can be hot forged. Depending on your request, we can propose a suitable material for you. There are alloys with focus on high mechanical properties, weldability, corrosion resistance or high surface quality after anodization.
Weighing only 1/3 compared to steel, aluminium allows for more flexibility in part design. Lighter parts result in a reduced inertness of fast moving parts and allow for performance advantages. Substituting steel by aluminium can solve some problems where the weight budged is at its limit. Gained weight savings by aluminium parts, can then be used In more critical areas.
Compared to steel, more complex and detailed geometries are possible when using aluminium alloys. Multi part assemblies can sometimes be replaced by a more complex single aluminium parts. Near-Net-Shape parts allow substantial cost savings.

Copper is mainly known for its high conductivity. But other properties set copper appart. It is antimicrobial and highly corrosion resistant. Pure copper is sometimes not suitable for highly stressed parts. Various copper alloys can address this shortcomings. All of them can be forged reasonably well to allow for many design options.
Kupfer eignet sich hervorragend für Copper is ideal for electronic components and live parts. It can easily be forged so that geometries can be optimized to only use the minimum required amount of the precious material.
In case of special requirements concerning hardness or strength, alloys exist that could be heat-treated to reach the required specifications. Some alloys allow for a drastic increase of standard pure copper properties.

Brass has many advantages. It can forged and machined exceptionally well to allow for minimal production costs.
Brass alloys are the best alloys when talking about hot-forging of non-ferrous metals. This allows for very delicate and detailed parts with a high degree of deformation. Combined with extraordinarily good cutting properties, automation levels and productivity levels when using brass are very high.
There is a wide range of brass alloys. Alloys can be selected depending on mechanical properties, corrosion resistance, machinability or environmental safety.

Titanium is known for its exceptional strength to weight ratio. This combination of “steel-strength” with minimal weight allows it to be the ideal candidate for extreme applications. Titanium forgings can be found in areaospace and aviation applications as well as in high end racing, sports or medical parts. Besides its good mechanical properties, titanium is highly corrosion resistant. This allows for applications where chemical products come in contact with parts were steel or other materials are not resistant enough. A better biocompatibility than steel allows titanium to be used in implants for patients with special needs.
Very good mechanical properties at minimal weight. Titanium allows for more design options in areas where weight efficiency allows to boos performance. Highly stressed parts in aviation, racing or medicine are typicaly titanium parts.
The forging of the already expectional titanium alloys can further increase its mechanical properties. Sensible products that are not allowed to fail, are often titanium parts. Forged titanium implants allow for light and reliable parts with minimal risk for failure.
