Beryllium Copper Plunger Tips
BeCu plunger tips for cold chamber aluminium die casting machines
Overview
What it is and where it works
Beryllium copper plunger tips for the shot end of cold chamber die casting machines. The alloy's thermal conductivity pulls heat from the tip face, which is why it has long been the standard for aluminium. Tips are softer than the shot sleeve, so fit, lubrication and cooling decide tip life. We source to your tip drawing and machine.
- Material
- C17200 for small and medium castings; C17510 for big castings and temperature-critical parts
- Wear behaviour
- BeCu tips are much softer than the shot sleeve; poor fit leads to wear, spalling or galling
- Failure mode
- Aluminium entering the tip-to-sleeve clearance erodes the tip and damages the sleeve
In your plant
Where It Is Used
- Cold chamber high pressure die casting of aluminium
- Shot ends with water-cooled plunger rods
- Replacement tips for existing machines

Frequently Asked Questions
How many shots should a tip last?
There is no single figure; it depends on sleeve fit, metal temperature, lubrication and cooling. Share your current shot count and we review the tip spec and lubrication with you.
Are there precautions with beryllium copper?
Yes. Machining or grinding BeCu generates particles that require exposure controls; normal handling of finished tips is not the issue.
