MIAMISBURG, OH—Allite Inc., a materials supplier specializing in lightweight products, has partnered with Weis Manufacturing to codevelop the first racing bicycle frame made entirely from the magnesium.

LOS ANGELES—Engineers at the University of California, Los Angeles (UCLA) have developed a way to weld an aluminum alloy that was difficult to join in the past.

If it rolls, floats or flies, lightweighting is one of the biggest challenges facing manufacturers today. The push for new materials is forcing engineers in a variety of industries to explore cost-effective alternatives and develop new assembly processes.

For the past decade, carbon-fiber composites have been the darling of the aerospace sector, receiving countless praise and widespread attention. Reinforced polymers have dramatically changed the way that many types of airframes are designed and built.

Efforts to reduce vehicle weight have mostly focused on aluminum, plastics and composites, but another lightweight material is also getting attention: magnesium. The ninth most abundant element in the universe, magnesium is as strong as steel, but 33 percent lighter than aluminum, 60 percent lighter than titanium, and 75 percent lighter than steel.

Back in the day, engines were the exclusive domain of cast iron and steel. But, during the past decade, more lightweight materials, such as aluminum and hard thermoplastics, have been slowly creeping under the hood. The Holy Grail, an engine made almost entirely out of plastic, is finally close to reality.

Carbon nanotube wiring is light, strong and efficient in transmitting electrical current.

Lightweighting has been a hot topic in the auto industry for many years.

DETROIT—General Motors uses seven joining methods—including spot welding, laser welding, self-piercing rivets and flow drill screws—to assemble the aluminum body of the new Cadillac CT6 sedan.

"Faster, higher, stronger” is the Olympic motto. It’s also the underlying philosophy behind the $25 billion U.S. sporting goods industry.
