Home Products Beryllium Products BERYLLIUM LIGHTER THAN ALUMINUM - STRONGER THAN STEEL In its natural state, beryllium is a lightweight, hard metallic element. Its modulus of elasticity is about one third greater than that of steel. Beryllium has excellent thermal conductivity and is non-magnetic. When used in alloys, beryllium hardens and strengthens other metals. For more than 80 years, Materion has been a leader in the development of beryllium-based metals. PRACTICAL APPLICATIONS OF BERYLLIUM The unique physical properties of beryllium make it ideal for x-ray and nuclear applications. Beryllium is transparent to x-rays, so its used as window material for x-ray tubes. Beryllium and its oxide, beryllia, are also used to blanket the core of nuclear reactors because beryllium slows down or captures neutrons. When small amounts are added to copper to produce copper beryllium alloys, the results include high heat resistance, improved corrosion resistance, greater hardness, greater insulating properties, and better casting qualities. Copper beryllium alloys are widely used in demanding applications such as aerospace, oil and gas drilling equipment, defense, avionics, and consumer electronics. THE BENEFITS OF BERYLLIUM Beryllium brings unrivaled advantages to its end-use applications, whether used in its pure metallic form or alloyed with other metals or as a beryllia ceramic. The use of beryllium has enabled technological breakthroughs previously thought unattainable. And, beryllium is recyclable. SAFE HANDLING OF BERYLLIUM Beryllium, its alloys, and its salts can be handled safely if certain work codes are observed, but no attempt should be made to work with beryllium before becoming familiar with proper safeguards.
