Description

Our alloys are used as plunger tips and moving plate bushings in the aluminum injection casting.
For plunger tips, we recommend AN-4, AN3S and AB-4 alloys for their high strength, good thermal conductivity, and ability to work on high operating temperatures. Thermal conductivity is critical for the cooling of the piston heads. Keeping the piston heads cooler than the molten metal is important to delay the deformation of the plunger tip, which heats up during thrust. Yield and tensile strength, hardness, and coefficient of elongation determine the life.
We recommend our alloys as the best option to be used as bushing material for good wear resistance and bearing combination.
