Frequently Asked Questions

Expert answers about our material capabilities.

1. How do I choose between Titanium and 316 Stainless Steel for a marine application?

Both offer excellent corrosion resistance. Titanium is superior in chloride environments (saltwater) and is about 45% lighter, but at a higher cost. 316 Stainless is a cost-effective choice for most marine applications. We cover this topic in-depth in our Titanium vs. Stainless Steel Guide.

2. What is a Mill Test Report (MTR) and why is it important?

An MTR (Material Test Report) is a quality assurance document that certifies a material's chemical and physical properties. It traces the material to its origin ("heat lot") and provides proof that it meets required standards (e.g., ASTM or ISO). It is essential for aerospace, medical, and other critical applications.

3. Can you source or work with a material not listed on this page?

Yes. This page lists our most commonly processed materials. We have an extensive network of qualified material suppliers and can often source specialty alloys or plastics for custom projects. Please contact us with your specific requirements.

4. How does material choice affect the final part cost?

Material choice is a primary cost driver. It impacts cost in two ways: the raw material price per kilogram and its machinability. For example, Titanium is more expensive per kg than Aluminum and also takes longer to machine, increasing both material and machining costs. We can provide quotes for different material options to help you make a cost-effective decision.

5. What does DFARS compliant material mean?

DFARS (Defense Federal Acquisition Regulation Supplement) compliance, as it pertains to specialty metals, typically means the material must be melted or produced in the United States or a qualifying country. This is a requirement for many US military and defense contracts. We can source and provide certification for DFARS compliant materials upon request.
