Material science is the fundamental building block of every industrial product. For procurement managers, the decision of which material to source is not just a decision of cost; it is a critical engineering decision that impacts the product’s performance, longevity, and safety. This article provides a deep technical dive into how to work with your engineering teams to make informed, data-backed material choices for complex industrial components.
We start by analyzing metallic materials. From standard stainless steels to high-strength tool steels and specialized nickel-based alloys, the range of choices is extensive. We discuss the importance of requesting ‘Mill Test Reports’ (MTRs) to verify that the chemical and mechanical properties of the raw material match your specifications exactly, protecting you from the risks of substandard material substitution.
Next, we pivot to the advanced world of polymers and engineering plastics. High-performance polymers, like PEEK and glass-filled nylons, now offer strength-to-weight ratios that challenge those of traditional metals. We analyze the properties of these advanced materials and explain how to design components to maximize their performance while minimizing manufacturing costs.
The final section is dedicated to the collaborative design process. We emphasize that material selection must be a dialogue between your design engineers and the supplier’s production engineers. The goal is ‘manufacturability’—choosing a material that performs its function flawlessly at the lowest possible cost to produce. By adopting this rigorous, engineering-led approach to sourcing, companies can avoid the pitfalls of improper material selection and build products that are superior in every performance metric.
