beryllium copper plunger tips


ALB-Alloy is capable of producing & machining beryllium copper plunger tips and the other pistons tips according to Customer’s drawing or available samples.


Plunger tips are made out of special copper alloys and are used to shoot the fluid aluminium or magnesium into the moulds of horizontal die casting machines. plunger tips can be made out of several special copper alloys grade like CuBe2, CoCoBe, CuNi2Be, CuCoNiBe and CuNiCrSi.


Available products:


The mainly available Custom Fabricated Plunger tips are C17200 beryllium copper plunger tips, C17500 beryllium copper plunder tips, C17510 beryllium copper plunger tips, CuCo1Ni1Be beryllium copper plunger tips.


Tips forms supplied are from rings, discs, square and rectangular sections, further machined to exact dimensions as well as customers’ required specification.


Typical application:

Aluminum die casting industry

Plastic Molding industry


Plunger tips are made out of beryllium copper as it has many advantages compaired to plunger tips made out of cast iron.

  • extra ordinary adjustable
  • low consumption of lubricant
  • improved cooling due to high temeperature conductivity enabling high working cycle rates
  • long life of plunger tip
  • long life of casting chamber
  • increase of casting capacity
  • reduction of casting costs


ALB-Alloy advantage:

Class 4 Alloy has extremely high hardness and ultimate tensile strength although the electrical conductivity is lower than the Class 3 Alloy

Class 4 Beryllium Copper (17200) is available in heat treatable tempers. Alloys are used in a wide range of applications requiring  high strength and stiffness with good conductivity.

Typical uses include electrical/electronic connectors, current-carrying springs, precision screw machined parts, welding electrodes, bearings, plastic molds and corrosion resistant components.


Class 3 Alloy is specifically recommended for projection welding dies, flash and butt welding dies, current carrying shafts and bushings.  As castings,
Class 3 Alloy (having higher strength than Class 2), is recommended for highly stressed welder structural current carrying members and heavy duty offset electrode holders.

Class 3 Alloy is generally recommended for spot welding and seam welding steels having high electrical resistance, such as stainless steels.
The Class 3 Alloy is heat treatable.
