grain direction aluminum plate standard

Knowledge of rolling direction does not have solely aesthetic benefits. During the machining of rolled aluminium, it is important to take the rolling direction into account. If, for example, aluminium bends the wrong way in relation to the rolling direction, there is a risk of breakage on the metal.

Aug 25, 2005· Does Aluminum plate stock (7075) have a grain direction that is significant enough to make a differance as to which direction a part should be made? 08-25-2005, 07:41 PM #2 A286

Applying this to metal bending, be it plate bending, press braking or any other type of metal forming, consideration must be given to the grain direction before any process is carried out. As a general rule, the grain line must run perpendicular to the bend to avoid the potential for cracking or fracture.

The Importance of Grain Direction. When working with plate, pay close attention to whether you are forming with (longitudinal) or across (transverse) the grain direction (see Figure 1). A plate’s grain direction comes from the mill’s rolling process, which stretches

Sheets of 2195 aluminum-lithium alloy were solution-treated at 507°C for 30min. One set was stretched to 3-5% in the 0°, 45°, and 90° angle with respect to the original rolling direction.

Dec 06, 2014· Elastic Constants: Finally we have the elastic constants, E, G and nu - Young's Modulus (x10^3 ksi) in this case is 10.7x10^6 psi, Shear Modulus (x10^3 ksi) in this case is 10.9x10^6 psi and Poisson's ratio of 0.33. Weight Density: Finally at the bottom we see the material density (weight density not mass density), in this case it is 0.1 lbf/in^3. . This value is critical when defining the

Second question - how does grain direction affect this? I have some ASME SA516 Gr. 60 plate, which is also dual certified to EN 10025 S275 J2. For the SA516 Gr. 60 it has been tested in the longitudinal direction at -51C. For the S275 J2 it has been tested in the transverse direction at -20C.

Tolerances: Sheet metal tolerances should not be tighter than necessary to make the part functional. Tight tolerances raise the cost of manufacturing significantly. Practical tolerances vary according to the design requirements. Tolerances of +/- .010 should be considered minimum. Linear tolerances should be held as loose as possible.

In products such as sheet and plate, the rolling direction is called the longitudinal direction, the width of the product is called the transverse direction, and the thickness is called the short transverse direction. The grain orientations in standard wrought forms of metallic products are shown the image.

Aluminum and Aluminum-Alloy Products, also called the Yellow Sheets. What is the minimum bend radius for an aluminum part? The bend radius large enough to avoid cracking is a function of the alloy, temper, thickness, bend orientation with respect to grain, and angle of bend. The 2015 Aluminum Design Manual Part VI Table

crack than coarse-grain steels of similar analysis. Also, fine-grain steels have greater fatigue resistance, and a fine grain size promotes a somewhat greater tough-ness and shock resistance. Steels made fine grained by addition of aluminum have machinability inferior to those made without aluminum. Also, cold working frequently alters grain

Oct 11, 2013· Sometimes the grain direction is bold, 11 x 17 would be grain long or 11 x 17 would be grain short. You may see the grain direction underlined, 11 x 17 would be grain long, or 11 x 17 would be grain short. Often on the label of a ream of paper, you will get multiple indications of the grain direction. For example, you may see “11 x 17
