This specification covers UNS A or A aluminum alloy extruded pipes and tubes intended for use in structural applications. Both alloys may be extrusion press solution heat treated to produce the specified tempers.

Each pipe or tube should be supplied with plain square-cut ends and mill finished unless otherwise specified. Samples for chemical analysis should be taken from the materials by drilling, sawing, turning, or clipping and subjected to suitable chemical or spectrochemical methods of analysis.

The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A for alloy in accordance with Practice E SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall asgm used independently of the other. Combining values from the two systems may result in non-conformance with the specification.

Rationalized [hard converted] SI units are shown in brackets while non-rationalized soft converted SI units are shown in parentheses.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the astk of regulatory limitations prior to use. The approval has been held by Mantec for over 20 years and was due for renewal in the summer of The magnetic rotor on an Eddy Current Separator produces the all-important separation force to recover or remove non-ferrous metals such as aluminium.


The multi-pole n429 rotor rotates at high speeds RPM and we assess whether higher speeds produce a better separation.

With business strong following two successful exhibitions Hillhead and RWMDavid was able to see a busy b29 floor. Blantyre water board are responsible for the quality of potable and waste water in the Blantyre city area.

They compliment the other water boards in Malawiwhich includes the Lilongwe water board, central b492 board, northern and southern water boards. Neil Durham the British CEO of Wagtech and Trace2o witnessed first-handthe fact that Blantyre central laboratory was unable to test for heavy metals, since their atomic absorption spectrophotometer was lying idle due a lack of spare parts, accessories, Be the first to comment!
