Working with AlBeMet AM162 SHT-O
Is AlBeMet AM162 easy to machine?
Machines like an abrasive Al-MMC with PCD or fine-grain carbide, high speed / light feed; all cutting, grinding and deburring must be wet or under HEPA extraction because Be-bearing dust is a chronic health hazard.
Can AlBeMet AM162 be welded?
Fusion welding is generally avoided (hot cracking, Be fume); electron-beam or laser welding with filler and Al-Si/Ag brazing or adhesive bonding are the accepted joining routes.
Can AlBeMet AM162 be formed, bent or molded?
Supplied as HIP block, extrusion or cross-rolled sheet; room-temperature ductility is only 2–7 %, so any bending or forming is done warm (200–350 °C) with generous radii.
What surface finishes work on AlBeMet AM162?
Electroless nickel plate is the standard finish (also enables optical polishing and diamond turning); chromate conversion or paint for corrosion protection — plain anodizing is patchy because only the Al phase reacts.

AlBeMet AM162 SHT-O — frequently asked
What is AlBeMet AM162 SHT-O used for?
AlBeMet AM162 SHT-O is typically used for avionics chassis, missile guidance structures, space optical benches and high-speed rotating components. In short: beryllium stiffness, better toughness; machinable Al-Be composite; high stiffness with 210 W/m·K.
What is the yield strength of AlBeMet AM162 SHT-O?
AlBeMet AM162 SHT-O has a typical yield strength of 255 MPa (37 ksi) and a tensile strength of 345 MPa (50 ksi) — weaker than 70% of refractory metal grades. Strength varies by condition: see the 3 listed tempers.
Is AlBeMet AM162 SHT-O easy to machine?
Reasonably — machinability is rated fair (45/100, better than 99% of refractory metal grades). Machines like an abrasive Al-MMC with PCD or fine-grain carbide, high speed / light feed; all cutting, grinding and deburring must be wet or under HEPA extraction because Be-bearing dust is a chronic health hazard.
Can AlBeMet AM162 SHT-O be welded?
Not readily — weldability is rated poor (25/100). Fusion welding is generally avoided (hot cracking, Be fume); electron-beam or laser welding with filler and Al-Si/Ag brazing or adhesive bonding are the accepted joining routes.
What surface finishes work on AlBeMet AM162 SHT-O?

Supplied as HIP block, extrusion or cross-rolled sheet; room-temperature ductility is only 2–7 %, so any bending or forming is done warm (200–350 °C) with generous radii.
What is the maximum service temperature of AlBeMet AM162 SHT-O?
AlBeMet AM162 SHT-O is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between AlBeMet AM162-HIP and AlBeMet AM162 SHT-CR?
HIP is the default condition — isotropic HIP consolidated billet/near-net shape — the standard stock form for machined instrument structures and housings. SHT-CR: highest-strength sheet condition; choose for stiffness/strength-critical flat parts that will only be machined, not formed. Yield strength is 193 MPa in HIP versus 330 MPa in SHT-CR.
