Description
Alloy Geek 2017 Aluminum Standard
Aluminum alloy 2017 is a high-strength alloy belonging to the 2xxx series of aluminum alloys. It's alloyed primarily with copper and can also contain small amounts of other elements. This alloy is known for its excellent machinability and good mechanical properties, making it suitable for applications that require both strength and the ability to be easily machined.
Composition:
- Silicon (Si): 0.2% - 0.8%
- Iron (Fe): 0.7% max
- Copper (Cu): 3.5% - 4.5%
- Manganese (Mn): 0.4% - 1.0%
- Magnesium (Mg): 0.4% - 0.8%
- Chrome (Cr): 0.10% max
- Zinc (Zn): 0.25% max
- Titanium (Ti): 0.15% max
- Others (each): 0.05% max
- Others (total): 0.15% max
- Aluminum (Al): Remainder
Key Properties:
- Machinability: Alloy 2017 is known for its excellent machinability, which makes it a preferred choice for applications where precision machining is a requirement.
- Strength: It offers good mechanical strength, particularly when compared to other non-heat-treatable aluminum alloys.
- Heat Treatment: While not as commonly heat-treated as some other alloys, alloy 2017 can be heat-treated to enhance its mechanical properties.
- Corrosion Resistance: Alloy 2017 offers reasonable corrosion resistance, but it may not be as corrosion-resistant as some other aluminum alloys.
- Applications: Due to its machinability and strength, alloy 2017 is often used in applications such as screws, bolts, fasteners, aircraft components, and other parts where machining and strength are key factors.
Like many aluminum alloys, properties can be influenced by factors such as manufacturing processes, heat treatments, and specific alloy variations. It's important to note that alloy 2017 contains a small amount of lead, which can enhance machinability but may also pose environmental and health concerns.
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.
