- Strength: Alloy 2024 is well-known for its high strength, making it one of the strongest non-heat-treatable aluminum alloys. It's often used in applications where structural integrity and strength are paramount.
- Machinability: While not as machinable as some other alloys like 2011 or 2017, alloy 2024 can still be machined effectively, particularly in the heat-treated condition.
- Heat Treatment: Alloy 2024 responds well to heat treatment, which can further enhance its mechanical properties, including strength.
- Corrosion Resistance: The alloy offers reasonable corrosion resistance, though it may not be as corrosion-resistant as some other aluminum alloys.
- Applications: Due to its excellent strength-to-weight ratio, alloy 2024 is used extensively in aerospace applications, including aircraft structures, fuselages, and wings. It's also used in military equipment, structural components, and high-stress parts.
It's important to be aware that alloy 2024 can be susceptible to stress corrosion cracking, especially in certain environments. This susceptibility is often reduced through proper heat treatment and surface protection.
XRF Samples are thinner samples approximately 1/4 inch thick. OES Standards are thicker in nature and are approximately 1 inch thick. Please Contact Us if you would like to know the specific dimensions of a sample.
Reference Material (RM): A reference material, or RM, is a material with a known composition or property that is used for informational purposes to look at analytical instruments, methods, or procedures. It serves as a point of comparison to ensure the accuracy and reliability of measurements. Reference materials can vary in terms of their level of characterization and traceability. Some reference materials may have well-defined properties, but they might not have undergone the rigorous testing and certification process that certified reference materials (CRMs) undergo. Reference Material chemical compositions are for information purposes.
Certified Reference Material (CRM): A certified reference material, or CRM, is a type of reference material that has been thoroughly analyzed and characterized using multiple validated methods to determine its composition or properties. The results of these analyses are then used to establish certified values, along with associated uncertainties. CRMs are produced and certified by accredited organizations or laboratories following internationally recognized standards, such as ISO Guide 34 (ISO 17034). The certification process includes interlaboratory comparison and statistical analysis to ensure accuracy and traceability.
In summary, the main difference between a reference material and a certified reference material lies in the level of characterization, validation, and certification. CRMs have undergone a more comprehensive and rigorous testing process, resulting in certified values and uncertainties that can be confidently used for instrument calibration, quality control, and research. Reference materials, on the other hand, can provide a point of comparison but do not have the same level of certification and traceability as CRMs. When accuracy and traceability are critical, certified reference materials are preferred.
