Beryllium Metal Disc

Description of Beryllium Metal Disc

Beryllium metal discs are produced from high-purity beryllium ingots, which undergo vacuum melting. These ingots are then multi-directionally forged, hot-rolled into slabs, and subsequently precision-punched or CNC-turned into circular sheets. Standard grade is equivalent to ASTM B826 Grade S-65F, and S-200F and O-30-H are available upon request. Finished products have diameters between 5 mm and 300 mm and thicknesses between 0.1 mm to 25 mm. Diameter and thickness tolerances of these discs are in line with ASTM E1876 high-precision standards, with diameter tolerances of ±0.02 mm and thickness tolerances of ±0.005 mm. Default surface roughness is Ra ≤ 0.4 μm and can be improved to as low as Ra ≤ 0.1 μm with chemical or electrolytic polishing methods.

Each batch of raw materials undergoes vacuum induction melting at 1280°C ± 20°C under a vacuum of 5×10⁻³ mbar. Then, a homogenization treatment at 1050°C for 4 hours is performed to achieve a uniform grain size and oxygen content below 600 ppm. Slabs are hot rolled before coiling at 800°C, with a 30% control on deformation for each pass. These slabs are rolled and then refreshed with 2 hours of 650°C annealing to relieve stress. Final discs undergo ultrasonically cleansing, IPA rinsing, and nitrogen drying within a cleanroom. Each disc is then individually packaged into double-layer vacuum bags and sealed with nitrogen. The bags are laser-marked with the batch number, diameter, thickness, weight, and RoHS compliance markings. The outer packaging is reinforced with EPE cushioning and anti-static aluminum foil. Each box includes an EN 10204 3.1 material certificate, MSDS, and beryllium safety instructions.
 

Features Of Beryllium Metal Disc

1. High strength, light weight, low density, and active chemical properties

2. Excellent transmittance to X-rays and other forms of ionizing rays

3. The sound transmission speed is fast, the transmission is particularly good, mostly used for top audio equipment and headphones

4. High modulus of elasticity, good thermal stability, low resistance, and high thermal conductivity

5. Long service life, cost-effective, and good environmental protection.

Applications Of Beryllium Metal Disc

X-ray/synchrotron radiation: acts as monochromators, focusing mirrors, or exit window substrates while enduring high-power beams.

Space optics: satellite mirror blanks or laser communication reflectors, which reduce weight while maintaining accuracy on laser mirror surfaces.

Semiconductor inspection: mask substrates for EUV lithography and x-ray fluorescence (XPF) sample holders, allowing for imaging a high resolution.

High energy physics: the windows and holders for the beam particle tubes, the components are made to withstand low scatter while maintaining a vacuum seal.
