Aero Metals is one of the very few investment cast foundries with the expertise to work in more exotic alloys for specialty applications like aerospace. Beryllium Copper (BeCu) castings provide many advantages in demanding commercial, industrial and aerospace applications. Aero Metals pours over 250,000 lbs of beryllium copper cast components per year. We have been casting beryllium copper since the early 1980’s and the demand for this specialty alloy has increased every year since.

There is nothing soft about a cast Beryllium Copper component. When heat treated, it is a high strength alloy with high thermal and electrical conductivity. This alloy offers hardness values greater than many steels, but with the thermal conductivity similar or greater than that of aluminum. Beryllium copper castings are ductile, can be easily welded and very easily machined.  It is also resistant to non-oxidizing acids and to plastic decomposition products.

Beryllium Copper casting alloys with 2.0% to 2.75% beryllium content provides outstanding wear, material toughness, and anti-galling characteristics. In challenging geometric shapes with thin walls and detailed internal passages, beryllium copper has excellent replication of these finer details.

These are the most widely used Beryllium Copper Alloys:

  • High Strength
    • C82500 (20C)          Be% 1.90-2.25    Co% 0.35-0.70    Si% 0.20-0.35                 Cu% Balance
    • C82800 (275C)        Be% 2.50-2.85    Co% 0.35-0.70    Si% 0.20-0.35                 Cu% Balance
  • High Conductivity
    • C82000 (10C)          Be% 0.45-0.80    Co% 2.40-270    Ni% -                             Cu% Balance
    • C82200 (3C)            Be% 0.35-0.80    Co% -                Ni% 1.00-2.00               Cu% Balance

Even though the material has a high conductivity, it does not spark and is non-magnetic. This material fulfills the requirements of the ATEX directive and is safe to use in “Ex Zones” where hazardous, flammable or combustible vapors, liquids, dust or residues may be present.
