2、Aluminum Association, Inc., represent approximately 85 percent of domestic production of primary ingot and shipments of U.S. aluminum mill products. Mill products include sheet and plate; foil; extrusions; electrical conductor and wire, rod and bar. In addition to producers of primary ingot and mill
3、 products, the associations membership also includes secondary smelters, foundries and producers of master alloy and additives. The association is a primary source of statistics, standards, and economic and technical information on aluminum and the aluminum industry in the United States. NOTICE Disc

17、 the title block near the right-hand margin. The note is required where any toler- ance is closer than standard tolerance is especially difficult to hold. The note will be: CRITIC= TOLERANCE. Exposed surface note: in the event the entire outside surface is exposed, a note reading ALL SURFACES EXPOSE
18、D will be shown to the right of the actual-size view. For hollow shapes the note will read ALL OUT- SIDE SURFACE EXPOSED. Radii notes: When a section involves several like radii it is often more practical to detail these by means of a note. This note is to be placed in the lower right-hand comer of
19、the drawing, above the title block. Examples: .XXX R on a l l inside and outside comers. (Use when a XXX R on a l l inside comers (hllets). (Use when a general XXX R on all outside corners. (Use when a general note general note is applicable to all c o m e r s . ) note is applicable to all inside co
20、mers.) is applicable to all outside comers.) Section VI1 - Lines and Line Work Weight of l i n e s : Two weights of lines are shown and considered desirable for section drawing. The two weights are heavy and medium light. Heavy line Approx width .O25 in. Medium light line Approx width .O10 in. H e a
21、 v y lines are used for shape outline only. Medium light l i e for all other lines. The actual widths of the above lines may vary with the type and size of the drawing as long as the proper contrast is retained. To insure proper reproduction it is necessary that all lines shall be uniform and f i r
22、m . Outlines: The outline of the section should be about 2% times heavier than all other dimension lines. Leaders: Leaders are composed of medium light lines, terminated by an arrow head. They should be curved only when necessary. The arrow head should touch the surface view to which the notes or di
23、mension applies. The leader should either precede or extend from the end of the note, and should run parallel to the body of the note for a distance and thence toward the part to which the note applies. Add EXCEPT AS NOTED to the above notes when applicable. As a second choice, it is permissible in
24、some cases to detail radii as follows: XXX R (3). The draftsman should make certain that this method of detailing could not be confused or misread. Typical note. Uniform wall thicknesses, of the like, may be detailed by a TYPICAL note when practical. Examples: .XXX TYP (after dimensions on the drawi
