Alloy Geek 2011 Aluminum Standard
Aluminum alloy 2011 is a high-strength, free-machining alloy that falls within the 2xxx series of aluminum alloys. This alloy is alloyed primarily with copper and can also contain small amounts of other elements. Similar to alloy 2007, alloy 2011 is known for its excellent machinability, making it a popular choice for applications where precise machining operations are required.

- Machinability: Alloy 2011 is renowned for its exceptional machinability, even better than other free-machining aluminum alloys. It produces short, broken chips, which aids in the machining process and helps extend tool life.
- Strength: It offers good mechanical strength, particularly when compared to other aluminum alloys, making it suitable for applications that require both strength and machining.
- Heat Treatment: Alloy 2011 can be heat-treated to improve its mechanical properties, including strength.
- Corrosion Resistance: Like other aluminum-copper alloys, alloy 2011 offers reasonable corrosion resistance, but it may not be as corrosion-resistant as some other aluminum alloys.
- Applications: Due to its excellent machinability and decent strength, alloy 2011 is commonly used in applications such as fasteners, fittings, screws, bolts, and other components that require precision machining.
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.
