ENGINEERING FAQ

Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Mill Test Reports (MTR) & Material Traceability Certifications.

What is a Mill Test Report (MTR)? +
An MTR (or Mill Test Certificate - MTC) is a certified quality document issued by the raw material manufacturer confirming the chemical and physical properties of a specific melt batch.
Is an MTR included with my order automatically? +
Yes. For aerospace, medical, and upon request for commercial projects, full EN 10204 3.1 Mill Test Reports are provided with your shipment documentation package.
How do you prevent raw material mix-ups in the workshop? +
Every incoming bar is color-coded by alloy, tagged with a unique internal barcode tied to its MTR, and stored in dedicated material racks before cutting.
What is Positive Material Identification (PMI)? +
PMI is a non-destructive testing method using X-ray fluorescence (XRF) to analyze the elemental composition of metal parts, verifying alloy grade before and after machining.
