The Material Selection Guide provides a concise framework for selecting the right metal for CNC machined components based on end-use requirements and design constraints. It outlines key factors such as environmental conditions, thermal exposure, conductivity, and mechanical loading, alongside procurement considerations like cost, lead time, and availability.

The guide highlights commonly used metals—aluminum, steel, brass, copper, and titanium—detailing their properties, machinability, and industry applications. For example, aluminum is praised for its strength-to-weight ratio and heat efficiency, making it ideal for aerospace and automotive parts. Steel variants offer versatility and affordability, while copper and brass excel in conductivity and corrosion resistance. Titanium stands out for its biocompatibility and resilience in high-performance environments.
