BIBUS METALS, one of the best established European titanium distributors with world-wide network chose a very special retirement gift for its CEO, Mr. Martin Vonmoos. The 40 years old, Zürich-based company ordered Gömböc 2015 to be manufactured from grade 2, pure titanium, offering a formidable manufacturing challenge. After aluminium-alloy, clear and coloured plexiglass, copper, bronze, stainless steel and 99.99% certified pure silver, titanium is the seventh material form which a perfect Gömböc shape has been manufactured.
