How old beer cans helped Constellium crack open North America AN-LOGO-BLUE AN-LOGO-BLUE

MUSCLE SHOALS, Ala. — Billions of used beer and soft drink cans are the magic ingredient in Dutch aluminum supplier Constellium’s strategy for getting more aluminum into North America’s vehicles. Never mind who is out there drinking that many beers and soft drinks every year. It’s part of a supply chain equation that Constellium has worked out to raise its share of the U.S. market for automotive aluminum. In 2010, the North American demand for flat-rolled automotive aluminum was about 100,000 tons a year. By 2025, annual demand will be 1.4 million tons, Constellium forecasts. According to a widely cited market research study published two years ago by Ducker Worldwide, the use of aluminum will grow by 168 pounds per vehicle, to an average of 565 pounds, between 2015 and 2028. Automakers want lighter cars and trucks. Aluminum is a clear way to achieve that, as Ford Motor Co. did in 2014 when it remade its F-150 pickup with an aluminum body, dropping 700 pounds and signaling to the industry that a new era had arrived.

Like the XPS 13, Dell expanded its XPS 15 lineup to include a 2-in-1 model. It looks similar to the clamshell one, it has similar hardware inside, and it also has a gorgeous display. Prices are likewise closely matched, and you might be wondering exactly which model is best for you. Let’s break things down to help you make a final decision. The overall look and design of the clamshell XPS 15 lineup hasn’t changed a whole lot over the last few years, sticking with the carbon-fiber inside and CNC-machined aluminum outside. It’s a proven design, and as long as you’re not tired of the look, it should serve you well. The newer 2-in-1 model has taken that classic feel and added two convertible hinges to a thinner and smaller chassis, with the same silver exterior and black interior option; there’s also a brushed onyx color available for the 2-in-1. Both laptops are built extremely well and should put up with a lot of abuse. The backlit chiclet keyboard on the XPS 15 is a delight to use, and the large Precision touchpad on either laptop has plenty of room for multi-touch gestures. It should ultimately come down to a personal test of both laptops, but the X...
