High strength super light-weight tubing

rohre
Bolzen mit Knopfdruck-Verriegelung für zahlreiche Anwendungen, besonders im Flugsportbereich und in der Reha-Technik.
Schaft, Achse und Sperrkugeln dieses seit 20 Jahren bewährten Qualitätsprodukts bestehen aus hochfestem Edelstahl. Drei Sperrkugeln anstelle der sonst üblichen zwei bewirken doppelte Auszugsfestigkeit.
Ausführung mit zwei Kugeln und Sonderlängen auf Anfrage!
Die als Zubehör erhältlichen Sicherungsabschlusskappen mit eingepresstem Stahlring verhindern, dass die Sperrbolzenkugeln verschmutzen, einfrieren oder beschädigt werden.
Bruchlast in Querrichtung zweischnittig 2,8 t.
Finsterwalder is famous for a large selection of high strength super light-weight tubing from special aluminium alloys unavailable elsewhere. The tubing is also used for sport aviation purposes. We should like to draw attention to the fact, that each individual tube should be specially tested when used in safety critical situations.

In Finsterwalder gliders you will exclusively find tested tubings made from alloy 7075 (Perunal)!

  Abreviations:
  L = Length of uncut tube (minimum order) Tm* = Moment of inertia: Information about the rigidity and compression stability of the tube. Is for all practical purposes independant of the alloy type and tensile strength.
  54 x 0,9 = Outer-Ø 54 mm, wall thickness 0,9 mm  
  F =
Tensile and compression strength per mm² (is also the measurement for bending)

 

Please note,

 

that the tubes are usually available only in the length stated below. Other lengths are sometimes available, however the delivery times are usually very long.

Tubes over 2 m length sometimes cause high packing and shippping costs. If desired we will cut the tubing for you at the nominal cost of € 0,30 per cut. We must also charge for unusable off cuts. The minimum order is 1 tube. We have no off cuts resulting from our glider production.

For purchase over € 500,-- in value per tube measurement, we are able to offer discount. Please call us and ask for a quote.

When picking up orders, please give us one day's notice.
