# Material Selection Guide for High Pressure Die Casting Components

###  Eliminating Guesswork When Selecting Components for HPDC 

HPDC tooling decisions get expensive fast when materials are chosen on habit instead of data. This guide gives you a practical way to shortlist AMPCOLOY® alloys for pistons and piston-adapter systems, using thermal conductivity (W/mK) and hardness (HBW), plus cooling flow ranges tied to piston diameter. It also covers venting selection with cross-section options for natural and vacuum concepts, along with the design checks that keep vent paths working over long runs.

Download the technical paper for the full tables and a selection workflow you can reuse in design reviews.
