# Aluminium **Aluminium is the primary reference material used throughout this documentation.**\ It represents a meaningful step beyond typical entry materials used on compact CNC machines — challenging enough to require proper strategy and tooling, but still well suited to desktop machines when treated correctly. Different alloys and tempers behave very differently. Even within “aluminium,” machining characteristics can range from smooth and predictable to sticky, vibration-prone, or highly sensitive to load and chip evacuation. This section focuses on practical observations from dry milling:\ which alloys behaved predictably, which exposed machine limits, and why. *** ### Related Pages Where to buy / sourcing --> [Sourcing Tools & Materials](/miwicnc/sourcing-tools-and-materials.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://miwicnc.gitbook.io/miwicnc/materials/aluminium.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
