Ampco Metal AMPCOLOY® 83 Beryllium Copper, Extrusion
Categories: Metal; Nonferrous Metal; Beryllium Alloy; Copper Alloy

Material Notes: AMPCOLOY 83 is a 2 % Beryllium copper alloy which displays very high mechanical properties with a reasonably good electrical and thermal conductivity.

Applications: Wherever good wear resistance or high mechanical properties are desired coupled with a good electrical or thermal conductivity, such as: flash butt welding and butt welding; parts for electrical components. In the plastic mould industry AMPCOLOY 83 is sometimes used as chill plates and inserts in the moulds, cooling pins and neck rings or bottom plates for blow moulds of plastic bottles.

Key Words: CDA C17200; RWMA Class 4; DIN 17672 W.Nr. 2.1247; EN 101C Typ A4/2; AFNOR UBe2
