Engineered for Extremes. Measured by LECO.
In industries where failure is not an option, for example—aerospace, automotive, energy, medical, and advanced manufacturing—materials must perform under the most extreme conditions. Whether it’s withstanding temperatures above 1000 °C, resisting corrosion in chemically aggressive environments, or maintaining structural integrity under high stress, the demand for high performance materials is only increasing as our world continues to innovate.
With so much at stake, it’s critical to ensure your high performance materials are truly ready to perform. But performance doesn’t begin on the production line—it begins in the lab.
LECO helps engineers, scientists, and quality professionals solve the toughest analytical challenges in material development, compliance, and failure prevention.
Our solutions span the full spectrum of elemental analysis, thermal analysis, mass spectrometry, and metallography workflows. With reliable instrumentation, your lab is empowered to make confident decisions with accurate, repeatable data.
Whether your work is research-based or rooted in quality assurance, our systems are designed to streamline workflows, reduce variability, and deliver actionable insights.

You can also request a chat with an industry expert to find the right solution for your organization.
Solving Problems in Metals and Alloys
Industries working with titanium alloys, nickel-based superalloys, high-strength steels, aluminum alloys, and refractory metals face critical questions.
• Is the elemental composition within spec?
• Will this batch meet fatigue and thermal resistance requirements?
• Can we detect trace contaminants before they cause failure?
LECO provides solutions for Oxygen/Nitrogen/Hydrogen analysis, Carbon/Sulfur determination, and microstructural evaluation, ensuring your materials meet the strictest performance and safety standards.
Tackling Complexity in Polymers and Composites
High performance polymers—like Polyimides (PI), Polyether ether ketones (PEEK), fluoropolymers (PTFE), and their composites—are essential in lightweight, high temperature, and chemical resistant applications, but they also come with challenging questions that need to be answered.
• What’s the ash or filler content?
• Can we identify unknown contaminants or breakdown products?
LECO’s organic and thermal analysis instruments quantify nitrogen, moisture, ash, carbon black, and additives. Our GC-MS instruments can be used to accurately separate and detect trace contaminants or quantitate regulated substances in a variety of sample materials.
Solving Analytical Challenges in Advanced Semiconductor Materials: SiC Purity and Layer Composition
In the semiconductor industry, even the slightest impurity or structural flaw can undermine device reliability. From ultra-pure silicon wafers to advanced ceramics like silicon carbide, manufacturers face critical questions.
• Is the Oxygen content in Silicon Wafers below critical limits to prevent performance degradation?
• Are dopant and thin-film layer compositions uniform and within spec throughout their depth?
• Can we detect trace contaminants (O, N, H, C, S) before they cause device failures?
• How can we differentiate and measure residual free Carbon vs. bound (carbide) Carbon in Silicon Carbide?
• Are the microstructures of wafers and electronic components free of defects after processing?
LECO provides solutions for Oxygen/Nitrogen/Hydrogen analysis, Carbon/Sulfur determination, quantitative depth profiling, and metallographic evaluation, ensuring your semiconductor materials meet the strictest purity and performance standards.
Ensuring Structural Integrity with Metallography
• Sample preparation from sectioning to polishing
• Hardness testing for weld zones, coatings, and heat-treated parts
• Optical imaging and grain size analysis for microstructural validation
