Metal Grain Direction: What You Need To Know - AAA Air Support
A metal's grain direction is usually only a factor when bending, however. This is because sharper, or tighter, bends can be made across the grain without cracking. In addition, the grain direction needs to be considered when the bend radius is less than twice the thickness, depending on the material and its hardness. Working With Grain Direction

Boron can be used alone (at levels of 0.005 to 0.1%) as a grain refiner during solidification, but becomes more effective when used with an excess of titanium. Commercial grain refiners commonly contain titanium and boron in a 5-to-l ratio. Cadmium is a relatively low-melting element that finds limited use in aluminum.
