Alloy 165 (UNS C17000)

Beryllium Copper Alloy

Alloy 165 Beryllium Copper

Alloy 165 is a beryllium-copper alloy which displays good strength. The material is non-magnetic and non-sparking with good conductivity. The alloy is easily machined and weldable using established welding methods. Alloy 165 also offers good strength in cryogenic conditions. The alloy inherently has good wear resistance.

Galling & Wear Resistance

Alloy 165 offers inherently good wear resistance. Threaded joints of beryllium copper in contact with itself and also stainless steels show good resistance to galling.


Alloy 165 is a non-sparking, non-magnetic alloy which offers good strength and good conductivity. The alloy can be easily machined with similar characteristics to free-cutting copper alloys or stainless steels.

Typical Applications

Commercial applications for this engineering material include:

  • Bearings and bushes
  • Resistance welding equipment
  • Pins and inserts for plastic injection moulds
  • Anti-galling wear plates
  • Guide rails and bus bars
  • Fasteners

We stock Alloy 165 in a variety of shapes.
