Beryllium Properties and Specification

Beryllium properties and specification data help engineers decide whether it suits a design. Key figures include density, stiffness, conductivity and melting point. 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. NGK Berylco brings decades of experience with beryllium and its alloys, plus quality systems built for regulated industries.

NGK Berylco alloys go into aerospace, automotive, electronics, telecommunications, energy, defence, medical, hydrogen, home appliances, watchmaking and oil and gas applications. Wherever strength, conductivity and reliability have to work together, these materials earn their place.

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.

Buyers in regulated sectors need paperwork they can trust. NGK Berylco is certified to ISO 9001, EN 9100, ISO 14001 and ISO 45001, with a dedicated laboratory and a product compliance programme behind its alloys.
