General Capabilities
In our metallurgy lab, we look closely at materials, part performance, and coatings to make sure they meet expectations. Capabilities include:
- Material testing and microstructure analysis
- Scanning Electron Microscopy (SEM) equipped with EDS
- Strength testing (Tensile and Crush)
- Density, porosity, and hardness measurements
- Corrosion and torque testing
- Dimensional change evaluations
These services provide the data you need to confirm your parts meet design intent, regulatory requirements, and end-use expectations.

Understanding the structure of a component at the microscopic level is crucial for predicting its performance.
- Optical microscopy allows us to evaluate grain size, porosity, and coatings.
- SEM with Energy-Dispersive Spectroscopy (EDS) enables the analysis of chemical composition and defect identification.
These results help pinpoint failure causes and confirm that parts are built to last.
Strength Testing
Strength testing measures how well a component resists the forces it’s designed to carry.
- Tensile Testing (MPIF Standard 10): Measures tensile properties of powder metallurgy materials.
- Crush Testing: Evaluates part performance under compressive loads.
Our strength testing processes align with ASTM and MPIF standards, giving you reliable data you can trust.
Density & Porosity Testing
Density and porosity play a big role in how powder metal parts perform.
- MPIF Standard 42: Density of compacted or sintered PM products.
- MPIF Standard 57: Oil content, surface-connected porosity, and oil-impregnation efficiency.
By measuring density and porosity, we help ensure components maintain consistent performance in demanding conditions.
Hardness & Tensile Properties
Mechanical properties are what make a part dependable.
- Microindentation Hardness (MPIF Standard 51): Evaluates localized hardness in powder metallurgy materials.
- Tensile Properties (MPIF Standard 10): Confirms parts meet strength requirements for their intended applications.
These methods provide manufacturers with assurance that their powder metallurgy products can withstand everyday wear and tear.
Radial Crush & Torque Testing
Powder metallurgy components often function in high-stress applications.
- Radial Crush Strength (MPIF Standard 55): Determines resistance to radial forces, commonly used for bushings and cylindrical parts.
- Torque Testing: Conducted per customer specifications to measure torque capacity in real-world conditions.
This testing ensures parts won’t fail under torsional or compressive stress.
Corrosion Resistance
For components exposed to moisture or harsh environments, corrosion testing is essential.
- ASTM Standard B895: Evaluates corrosion resistance of stainless steel PM parts through immersion in sodium chloride solution.
Our corrosion resistance testing provides confidence in long-term durability for automotive, appliance, and industrial applications.
Dimensional Change Characteristics
Dimensional stability is crucial for assemblies requiring tight tolerances.
- Dimensional Change Testing: Performed to customer requirements, evaluating how parts change during processing or under load.
This data ensures parts consistently fit and function as intended.
