A magnesium docking station designed specifically for the Toughbook 30 computer, the Gamber-Johnson Mag Dock utilizes the magnesium alloy AZ91-D, which contains aluminum and zinc as the primary alloys. Magnesium AZ91-D is the most appropriate metal of choice because it: has the highest strength-to-weight ratio of all structural metals, except for titanium; is exceptionally rugged, as well as dent-and-stress resistant; can be die-cast into very thin-gage, complex geometric structures at very exacting tolerances; presents a smooth, user-friendly surface that blocks electromagnetic interference (EMI), especially at higher frequency EMI used for commercial applications; readily dissipates heat and absorbs energy that dampens vibration and reduces noise; and is readily recyclable, abundant in nearly inexhaustible quantities, and extracted without non-toxic and nonpolluting byproducts. Another benefit of magnesium is that it is very light, yet exceptionally strong. The magnesium CF30 docking station weighs around six pounds, so it is less top-heavy, less likely to vibrate and compounds the strength of the mounting solution as a whole. That means less wear and tear on the computer and its connections.
