If you’ve been following the tech space this past week, you undoubtedly came across the numerous reports that LG’s latest flagship, the LG G5, was actually made of plastic rather than the all-metal build that LG has been advertising. This originated from a video from YouTuber JerryRigEverything who took a razor blade to his LG G5 and revealed a thick layer of plastic on top of the device. LG was quick to respond with a brief statement saying that the phone was all metal and that the plastic was due to that section of the phone containing antenna bands. However today they’ve come back with a more detailed response.
Contrary to erroneous reports online that the LG G5 body is composed of plastic, LG would like to state unequivocally that the uni-body casing of the G5 is composed of a special aluminum alloy, LM201 (Feb. 2016 patent pending). LM201 was developed by LG in partnership with the Korea Institute of Industrial Technology for use in high-end sports cars, aircraft and consumer electronic pducts where durability, rigidity and lightness are required. As a die-cast metal, LM201 was determined to be most appropriate material to accommodate the curves of the G5. After the die-casting is complete, the insulating antenna slit is applied directly to the aluminum casing followed by a coating of primer which provides additional insulation and enhances the surface profile for the “microdizing” process, where pigment containing tiny metal particles is applied directly to the primer to provide a smooth and durable finish. While both anodized aluminum and microdized aluminum will scratch if enough pressure is applied, in the case of the G5 the gray primer beneath the pigment layer may be mistaken for plastic when the coloring is scratched off. We want to reassure our customers that the uni-body of the LG G5 is advanced aluminum alloy, not plastic.
So to put all of that in simple terms, the LG G5 is indeed metal, but it has a coating on top that shows the device’s colors. If this color is scratched off it may look like plastic, but LG assures us that it is not and is rather a primer that has metallic particles within it. That primer also allows the device to avoid using antenna bands as the antenna technology is built into the primer itself.
Underneath that coating however is a special metal alloy which originally intended for use in airplanes and high-end sports cars, hence the device’s lightweight feel in the hand. Does this help instill a bit more confidence in the build on the LG G5? Let us know in the comments.
