Astm Specifications For Aluminum

Aluminum specifications by ASTM are based on the use of the material.


ASTM International, formerly The American Society for Testing and Materials, issues standards for material specifications, usage and testing. ASTM aluminum specifications are issued by ASTM's Committee B-7. ASTM specifications are based on the product type rather than the alloy. The American Society of Mechanical Engineers (ASME) has adopted some ASTM material specifications for aluminum. Does this Spark an idea?


Aluminum Specifications


ASTM specification B209 applies to aluminum sheeting and plating. ASTM specification B210 covers drawn seamless tubes. ASTM specification B211 is for aluminum bar, rod and wire, while ASTM B221 applies to extruded aluminum in the form of bars, rods, wires, and tubes. ASTM B316 defines the specifications for aluminum rivets. B308 applies to aluminum 6061 standard structural profiles. ASTM B247 is the specification for aluminum die forgings. ASTM B241 provides the specification for seamless aluminum pipe. Aluminum flake pigments are specified in ASTM D692, part 28.


Aluminum Alloy Specifications


ASTM F1108 is the specification for titanium/aluminum/vanadium alloy used in surgical implants. ASTM F136 is the specification for titanium/aluminum/vanadium extra low interstitial alloy used in surgical implants. Aluminum-zirconium wire specifications are defined by ASTM B941. ASTM B233 sets the allowed levels of impurities in aluminum and its alloys.


Testing


ASTM specifications for aluminum include testing of the material.


Aluminum particle size distributions can be found using sedigraphy per ASTM standard B761. Measuring particle size via a Fisher subsieve sizer is done in accordance with ASTM B330. ASTM B822 describes measure particle sizes via light scattering. Fracture toughness for aluminum is found via ASTM E39. Stress corrosion of aluminum can be found using the process outlined in ASTM G47. Aluminum hardness can be determined using ASTM E84, the Vickers hardness test. ASTM B645 is the standard practice for plane-strain fracture testing of aluminum alloys. ASTM B909 is used to test fracture toughness of non-stress relieved aluminum. Exfoliation of aluminum alloy is tested per ASTM G34.


ASTM Non-Ferrous Standards


ASTM has issued standards for non-ferrous building materials. Non-ferrous building materials include those made from aluminum. ASTM F468 covers hex cap screws and bolts, including those made from brass and aluminum. ASTM F468M is the metric specification for hex cap screws and bolts.


ASME Specifications


According to "Aluminum Structures" by J. Randolph Kissell and Robert Ferry, "ASME aluminum specifications are nearly identical to ASTM specifications of the same name except that ASME specifications only include those alloy tempers included in the ASME Boiler and Pressure Vessel Code." ASME standards for aluminum adopted from ASTM have "S' in front of the ASTM specification. ASTM B136 becomes ASME SB136.
