We have expertise from strip material to tube drawing to the finished component - a challenging process chain that we have mastered at our site in Aura im Sinngrund for decades. In addition to primary materials purchased from quali- 

 

fied suppliers worldwide, we can also weld primary material for precision tu- bes at our site. For welding, we use the tungsten inert gas (TIG) welding meth- odThanks to a continuous inspection of the weld seam with eddy testing and 

highly qualified employees, we can cre- ate a material whose quality, after fur- ther finishing steps, speaks for itself. 

 

We manufacture all standard stainless steels, such as:

  • 1.4301

  • 1.4401

  • 1.4404

  • 1.4571

  • etc.

Moreover, we also process special alloys, e.g.

  • 2.4967, L605: UNS R30605 (AISI 670)

  • 2.4711, Phynox: UNS R300003   UNS R30008 (ASTM F 1058 (Elgiloy)

  • 2.4999, MP35N: UNS R30035 (ASTM F562)

  • 1.4568, 17-7PH: UNS S17700 (AISI 631)

  • 2.4360, Monel: UNS N04400 (ASTM B165) (Alloy 400)

  • 2.4068, Nickel 99.2: UNS N02201 (ASTM B161) (Alloy 201)

  • 2.4816, Inconel: UNS N06600 (Alloy 600) 

  • etc.

 

OD ≈ from 0.15 to 28 mm 

ID ≈ from 0.05 mm 

High precision wall thickness ≈ from 0.03 – 2.5 mm

Are you looking for alternatives to a

round tube? Oval, square and drop-

shaped profiles are also feasible and 

may be the right solution for you.

 

Maximum manufacturing lengths of 6m.

 

We fulfill your requirements for a high precision tube.

Tolerances in a range of +/-0.005 mm are not uncommon for us in many dimensional ranges.

 

Drawn and grinded surfaces.

For higher demands, we can map roughness values significantly below Ra 0.50 µm, in some cases down to Ra 0.15 µm.

 

Tensile strengths of 500 - 1.800 N/mm²
