Alufast®
Aluminium screws

Particularly in the automotive industry, the trend is towards lightweight materials. Aluminum and magnesium alloys use are increasing in many fields of technology. So it’s necessary for fastening technology also to adapt too. 

Aluminum has very many possibilities because this material is extremely versatile in the cold forming process. 

ARNOLD supplies aluminum screws under the Alufast® product name. Our many years of experience working with aluminum ensure that you have the best fastening results. We are continually optimizing our processes to maintain our Alufast® products at the latest state of technology.

Reducing 
weight

Aluminum screws from the ARNOLD Alufast® range are primarily used in the automotive industry. We use EN AW 6056 (AlSi1MgCuMn) alloy as our original material, known by its designation class of AL9. Due to the low E-module, the flexibility of an aluminum screw is much greater than that of a steel screw (EAI=70000 MPa, E=210000 MPa).

Alufast® – Not just a fastener

Aluminium screws from our Alufast® range are primarily deployed in the lightweight automotive industry. Particularly when combined with magnesium, aluminium or synthetic components, aluminium delivers many benefits. We use EN AW 6056 (AlSi1MgCuMn) alloy as our original material, known by its designa- tion class of AL9. Depending on the customer's requirements certain characteristics can be set using our optimally adjusted processes (see table).

Alufast® aluminium screws and form parts

The trend – particularly in the automotive industry – is towards light-weight materials. Aluminium and magnesium alloys are in increasing use in many fields of technology. So fastening technology needs to adapt too. Aluminium offers countless options because the material is so versatile for cold forming. Under the Alufast® name ARNOLD UMFORMTECHNIK has brought together screw fasteners and form parts made from aluminium. Our many years of experience work-ing with aluminium, including extensive research are your guarantee of optimum fastening results. We are constantly optimising our processes, ensuring that our Alufast® products are always at the latest state of technology.
