  2. Introduction • The material chosen for the structural tube is AlBeMet AM162 from Materion (former Brush Wellman), which consists of 62% Be and 38% Al. • Beryllium dust is highly toxic, therefore special precautions are needed for machining, e.g. encapsulated machines. • Only few workshops available in Europe (UK, D, CH). • Coating companies not always treat Beryllium and its alloys. • ITAR situation: • Raw material just needs end user declaration. • (Semi-)finished parts are subjects to export restrictions.

  3. Feasibility Study • End of 2010 a contract was placed at APCO to carry out a feasibility study focused on: • Procurement of raw material • Machining • Coating (anorganic) • A report with ecouraging results was provided (A4.AN.37294, dated 10 May 2011). • Some weeks after formal contract closure coated samples from different suppliers were provided to UBE, whereby excellent results could be observed. • The outcome of the feasibility study was definitely positive.
