Beryllium for watchmaking appears mainly in beryllium copper springs and fine parts where stable elasticity is essential. With more than 50 years in high performance copper alloys, NGK Berylco supplies UK, Irish and Nordic customers through its Salford office, backed by the wider NGK Group.

Beryllium metal combines properties that no other metal matches. With a density of about 1.85 g/cm³ it is roughly a third lighter than aluminium, yet around six times stiffer than steel and highly resistant to torsion. It conducts heat and electricity well, at over 40% IACS, resists corrosion and acids, is non-magnetic and anti-sparking, and barely oxidises. It melts at around 1,287 °C.

Beryllium is a specialist material and it pays to work with a specialist supplier. Discovered in 1798 and named after the mineral beryl, it is extracted mainly from bertrandite and beryl and has been on the EU list of critical raw materials since 2011. Reliable sourcing, controlled processing and proper documentation all matter.

Watchmaking needs tiny, precise components with stable spring properties and good corrosion resistance. Fine wire and strip from NGK Berylco suit the small, demanding parts found in quality timepieces.

NGK Berylco supplies pure beryllium as windows, mirrors and other components. Beryllium is about 17 times more transparent to X-rays than aluminium at the same thickness, which makes it the standard material for X-ray windows in medical and security imaging. Beryllium mirrors serve advanced optical applications, and other components draw on its light weight, stiffness, non-magnetic and nuclear properties.

Quality is not left to chance. NGK Berylco holds ISO 9001, EN 9100 for aerospace, ISO 14001 and ISO 45001, and runs its own testing and inspection laboratory alongside an active R&D programme.
