Working with AlBeMet AM200-HIP
Is AlBeMet AM200 easy to machine?
Machine wet with sharp PCD/carbide tooling at moderate speeds; all beryllium-bearing swarf and dust must be captured (HEPA/wet collection) under OSHA/EU beryllium exposure controls, and machined surfaces are usually etched to remove damaged layer.
Can AlBeMet AM200 be welded?
Fusion welding is not recommended (hot cracking of the Be phase); joints are made by electron-beam/laser welding with qualified procedures, aluminium-silicon brazing, or mechanical fastening and bonding.
Can AlBeMet AM200 be formed, bent or molded?
Essentially non-formable cold; bending and stretching require warm working around 200–400 °C, and near-net HIP shapes plus machining are the normal route.
What surface finishes work on AlBeMet AM200?
Chromate conversion, electroless nickel plate (for polished/optical surfaces) or primer-paint are standard; anodizing gives a patchy film because the beryllium phase does not oxidise uniformly.
AlBeMet AM200 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

AlBeMet AM200-HIP — frequently asked
What is AlBeMet AM200-HIP used for?
AlBeMet AM200-HIP is typically used for aerospace structural components, satellite frames and high-stiffness lightweight brackets. In short: al-Be structural alloy; high stiffness-to-weight; extrudable Be-bearing alloy.
What is the yield strength of AlBeMet AM200-HIP?
AlBeMet AM200-HIP has a typical yield strength of 200 MPa (29 ksi) and a tensile strength of 275 MPa (39.9 ksi) — weaker than 87% of refractory metal grades. Strength varies by condition: see the 2 listed tempers.
Is AlBeMet AM200-HIP easy to machine?
Not especially — machinability is rated fair (35/100, better than 81% of refractory metal grades). Machine wet with sharp PCD/carbide tooling at moderate speeds; all beryllium-bearing swarf and dust must be captured (HEPA/wet collection) under OSHA/EU beryllium exposure controls, and machined surfaces are usually etched to remove damaged layer.
Can AlBeMet AM200-HIP be welded?
Not readily — weldability is rated poor (20/100). Fusion welding is not recommended (hot cracking of the Be phase); joints are made by electron-beam/laser welding with qualified procedures, aluminium-silicon brazing, or mechanical fastening and bonding.
What surface finishes work on AlBeMet AM200-HIP?
Chromate conversion, electroless nickel plate (for polished/optical surfaces) or primer-paint are standard; anodizing gives a patchy film because the beryllium phase does not oxidise uniformly.
Can AlBeMet AM200-HIP be formed, bent or molded?
Essentially non-formable cold; bending and stretching require warm working around 200–400 °C, and near-net HIP shapes plus machining are the normal route.
What is the maximum service temperature of AlBeMet AM200-HIP?
AlBeMet AM200-HIP is rated for continuous use to about 250°C (482 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between AlBeMet AM200-HIP and AlBeMet AM200-ANN?
HIP is the default condition — standard stocked form: isotropic consolidated block/billet for machined brackets, housings and optical benches. ANN: use after rough machining of precision optical or metrology parts to remove residual stress and maximise dimensional stability. Yield strength is 200 MPa in HIP versus 180 MPa in ANN.
