1 NIONL NORHES CORPORION

2 NIONL NORHES CORPORION National Northeast Corporation is a leading extruder and fabricator of aluminum structural shapes and components. ith more than fifty years of manufacturing experience, our five plants have a combined annual capacity of more than 40 million pounds of extruded aluminum. Our production operations consist of 500,000 square feet of manufacturing and warehouse space, several hundred pieces of machinery and a complete plating facility. his includes four extrusion presses capable of extruding any of the 6000 series aluminum alloys from the very simple to the very complex, from a minimum circle size of.250" to a maximum of 12.00", reaching aspect fin ratios of 16 to 1. In addition to our vast extrusion capacity, we feature inhouse capability, incorporating the latest in fabrication and anodizing technologies. From billet to finished product, National Northeast ensures the quality of the entire process. e are proud to say that we are one of the few companies today that offer design and engineering services. his luminum Extrusion Shapes Catalog contains many industry standard profiles. If you cannot find what you need, please contact us directly. e welcome the opportunity of adding to our vast inventory of over 15,000 assigned dies. In the case of all extrusions both old and new, standard aluminum extrusion tolerances will apply unless specifically waived by mutual agreement. e continue to specialize in difficult, tight tolerance applications that rival many machined features. For your convenience we have included in this catalog the tolerance specifications as established by the luminum ssociation Inc. (luminum Standards and Data, 1993). If at any time you require clarification or suggestions, our Engineering Department is available to answer questions or assist in the design of a new extrusion profile. Quality and ontime delivery are principles that drive our everyday performance and make National Northeast, the primary source for all your aluminum extrusion and fabricating needs. By controlling the entire process, from raw material through finishing and assembly, we are able to offer precision products for the best possible value with the shortest possible leadtime. hether your application is industrial, architectural, recreational, or electronic components, E can do it! Undoubtedly, E already have. Let National Northeast Corporation be the source for all your extrusion and fabrication requirements. dditional literature on various products is available.

Footnotes: 1 hen the outside diameter, inside diameter, and wall thickness (or their equivalent dimensions in other than round tube) are all specified, standard tolerances are applicable to any two of these dimensions, but not to all three. hen both outside and inside diameters or inside diameter and wall thickness are specified, the tolerance applicable to the specified or calculated O.D. dimension shall also apply to the I.D. dimension. 2 hen a dimension tolerance is specified other than as an equal bilateral tolerance, the value of the standard tolerance is that which applied to the mean of the maximum and minimum dimensions permissible under the tolerance for the dimension under consideration. 3 Mean diameter is the average of two diameter measurements taken at right angles to each other at any point along the length. 4 Not applicable in the annealed (O) temper of if wall thickness is less than 2 1 1/4 2 percent of outside diameter or equivalent round diameter. he equivalent round diameter is the diameter of a circle having a circumference equal to the perimeter of the tube. 5 he mean wall thickness of round tube is the average of two measurements taken opposite each other. he mean wall thickness of otherthanround tube is the average of two measurements take opposite each other at approximate center line of tube and perpendicular to the longitudinal axis of the cross section. 6 hen dimensions specified are outside and inside, rather than wall thickness itself, allowable deviation at any point (eccentricity) applies to mean wall thickness. 7 olerances for 3510, 4510, 6510, 73510, 76510, and 8510 tempers shall be as agreed upon between purchaser and vendor at the time the contract or order is entered. 8 X510 and X511 are general designations for the following stressrelieved tempers: 3510, 4510, 6150, 8510, 73510, 76510; and 3511, 4511, 6511, 8511, 73511, 76511, respectively. 9 hen weight of piece on flat surface minimizes deviation. 10 he circumscribing circle diameter is the diameter of the smallest circle that will completely enclose the cross section of the extruded product. 11 See Standards Section (6) for pplication of wist Limits. 12 olerances not applicable to X510, or X511 temper tube having a wall thickness less than Conditions include die lines, mandrel lines and handling marks. 14 For tube over O.D. the 2000 and 7000 series alloys and 5000 series alloys with nominal magnesium content of 3 percent or more are excluded. 15 Not applicable to O temper tube. 16 Limited to those alloys listed in table Not applicable to 2219 alloy tube. Most tubes in 2219 alloy will have die lines about twice the depth shown in the table; however, for each tube size the supplier should be contacted for the roughness value to apply. 18 If unspecified, the radius shall be 1 1/4 3 2 maximum including tolerances. 21 t: f: e: extrude@wakefield.com
