Light and easy fastening.

The trend – particularly in the automotive industry – is towards lightweight 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 working 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.

Aluminium screws

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:

  • lightweight
  • flexible
  • durable
  • stable
  • environmentally friendly
  • corrosion resistant

We use EN AW 6056 (AlSi1MgCuMn) alloy as our original material, known by its designation class of AL9. Depending on the customer's requirements certain characteristics can be set using our optimally adjusted processes (see table).
