8 Consequences of Using Incorrect Materials Can Range From: To

9 An Effective QA Program Must Include Alloy Material Verification X-ray fluorescence (XRF) technology has been the number one choice for alloy material verification in a wide range of industries for many years. X-ray fluorescence (XRF) technology has been the number one choice for alloy material verification in a wide range of industries for many years.

10 Benefits of XRF Analysis: Fast Results Positive identification and analysis data in seconds Accurate Data Newest generation instruments provide lab- quality data Non Destructive Can be safely used to test finished product Ease of use Simple to operate and maintain – doesn’t require technical expertise

11 XRF Analysis of Alloys Elements Analyzed with XRF Common Alloying Elements

12 Modes of Analysis  Fundamental Parameters (FP) Analysis  Calculates chemical composition through mathematical modeling and determines grade ID from composition  Spectral Signature Matching  Determines grade-only, based on similarity to one of a set of stored alloy spectral “fingerprints”  SuperChem  Determines grade and applies a “Type Standardization” for highly accurate chemistry on known (stored) grades  Fundamental Parameters (FP) Analysis  Calculates chemical composition through mathematical modeling and determines grade ID from composition  Spectral Signature Matching  Determines grade-only, based on similarity to one of a set of stored alloy spectral “fingerprints”  SuperChem  Determines grade and applies a “Type Standardization” for highly accurate chemistry on known (stored) grades

14 Chemical Analysis & Grade ID  Used for General Alloy Sorting and Identification where a wide variety of Alloys may be present.  Quick measurement times for Grade Identification.  Second measurement times for Alloy Chemistry  Used for General Alloy Sorting and Identification where a wide variety of Alloys may be present.  Quick measurement times for Grade Identification.  Second measurement times for Alloy Chemistry

15 Spectral Signature Matching Counts per second  AKA: “fingerprint identification”

16 How Does Signature Matching Work? Known Samples are measured, labeled and stored in the Spectral Signature Library SS 316 SS 304 Inco 718 An unknown sample is tested… SignatureLibrary Signature Library And then the spectral signature compared against those stored in the analyzer’s Signature Library.  When a match is found, the label associated with the signature is displayed. If a match isn’t found, the screen displays “No Match”

17 How Does SuperChem Work?  An analyzed sample or standard is used to determine exact intensities for each alloying element in a particular grade  Spectral Signature and intensity data are stored in SuperChem reference library along with composition data of stored sample  SuperChem Test: A spectral match verifies grade  Stored “single point” calibration is applied to the matched grade  Results are displayed: accuracy typically within 3 sigma precision  An analyzed sample or standard is used to determine exact intensities for each alloying element in a particular grade  Spectral Signature and intensity data are stored in SuperChem reference library along with composition data of stored sample  SuperChem Test: A spectral match verifies grade  Stored “single point” calibration is applied to the matched grade  Results are displayed: accuracy typically within 3 sigma precision

18 XRF and Aluminum Alloys Elements That Define Aluminum Alloys   

19 XRF and Aluminum Alloys Separation by Series XRF can be used for reliable differentiation of: 2000 Series vs 7000 Series vs 6000 Series XRF can be used for reliable differentiation of: 2000 Series vs 7000 Series vs 6000 Series High Cu Content High Zn Content Little to No Cu or Zn

20 Common Aluminum Alloys Separated Using XRF All of these alloys can be separated from one another, but not necessarily from others within the same series

22 Isotope Source vs. X-Ray Tube Source Both Isotopes and X-Ray Tubes are now available in Niton Field Portable XRF Units. Choose the one that best suits your Application.

23 Isotope Source Strengths and Limitations  Rugged and Durable  Smallest/Lightest Weight  Better Access to tight areas  Well Proven in field use  No Unexpected Downtime  Low Power Requirements  Widely Accepted and Trusted  Higher Temp Capabilities  Rugged and Durable  Smallest/Lightest Weight  Better Access to tight areas  Well Proven in field use  No Unexpected Downtime  Low Power Requirements  Widely Accepted and Trusted  Higher Temp Capabilities  May Require adding Fe-55 Source for specific alloy separations 304 vs. 321 K vs. R Monel Fe-55 has a 5-6 year replacement cycleFe-55 has a 5-6 year replacement cycle Second measurement requiredSecond measurement required  Licensing

24 Tube Source Strengths and Limitations  Best Performance/Faster Analysis  Wide Elemental Range  Reduced Regulatory Requirements  No Slowing or loss of Precision over time  Best Performance/Faster Analysis  Wide Elemental Range  Reduced Regulatory Requirements  No Slowing or loss of Precision over time Less Rugged than Isotope Less Rugged than Isotope Lifespan is Less Predictable Lifespan is Less Predictable Unexpected Downtime Unexpected Downtime Larger and Heavier Larger and Heavier Limited access to tight areas Limited access to tight areas Higher Power Requirements Higher Power Requirements No Long Term performance history No Long Term performance history

25 Isotope or Tube -You Choose  Ruggedness is imperative  Size and Weight are Concerns  High Temp Measurement capabilities are Crucial  Access via Inspection ports or to tight areas is necessary  Licensing is not a major concern  Ruggedness is imperative  Size and Weight are Concerns  High Temp Measurement capabilities are Crucial  Access via Inspection ports or to tight areas is necessary  Licensing is not a major concern  Latest and Greatest Technology  Speed and precision are of paramount concern  Little or no High Temp samples  Ruggedness not primary concern  Size and Weight are not an issue  Licensing requirements are a primary concern
