At the Avisma titanium foundry, a once-secret factory that made nuclear missile parts during the cold war, titanium ribs for Boeing airplanes are stacked in piles like lumber. In an annex, a Boeing and Avisma joint venture called Ural Boeing Manufacturing grinds forged parts destined for America. A third of all Boeing jet landing gear assemblies are made with titanium beams from Russia.

The Russians make titanium parts that are unseen but no less important on planes like the new 787 Dreamliner and the workaday commuter airplane, the 737.

Boeing buys so much titanium from Russia — the airplane maker plans $18 billion in purchases over the coming decades — that it now researches new alloys with the Russians. In Moscow, a thousand miles to the west, a team of 1,400 aerospace engineers designs airframes and wings, in part using Russian titanium components.

That titanium is taking off is a bright spot for Russia’s struggling aerospace industry. It is as welcome for Boeing. With the new Dreamliner airplane, Boeing took a leap into new technologies and a wider global network of suppliers. The strategy went spectacularly astray with a new lithium-ion battery made in Japan. The risk of battery fires forced Boeing to ground the entire fleet for months.

But the Russian titanium strategy is paying off. Reliance on Russian titanium, thought it comes with geopolitical risks given tensions between the United States and Russia, is making the lightweight metal more economical, so Boeing uses more. Reducing the weight of planes makes them more economical to operate and thus more attractive to the airlines. The Avisma factory, deep in a pine forest, makes 35 percent of all titanium for Boeing civilian airplanes.

“There are parts that only we make. Nobody else,” Mikhail V. Voevodin, the factory director and a part owner, said.

Titanium parts are devilishly difficult to make. In the foundry’s forge, gigantic circular furnaces rise along the walls of the main smelting hall, like the pipes of some volcanic organ in a cathedral from hell, six stories high. Electricity melts the metal in these vacuum tubes.

Gigantic struts, poles and sheets are heated until they glow red and are plunged into water baths, where they are banged with hydraulic hammers weighing five tons. They emerge amazingly strong.

“Russia is a critical partner for 787 titanium parts,” Sergey Kravchenko, the director of Boeing’s office in Russia, said in a written response to questions. The factory “has the largest in the world press for titanium forgings and Boeing takes full advantage of this unique capability,” he wrote.

Russians began using titanium in Vostok, the space capsule Yuri Gagarin flew in 1961. By the 1970s, Soviet generals had taken a shine to the metal. A secret program began, requiring incredible resources. In addition to airplanes, the Soviets would make submarines from titanium.

A half-dozen Alfa, Mike and Papa class attack submarines came out with hulls that were 30 percent titanium by weight, according to a museum at the factory. Each required more than 2,000 tons of the metal. Light and strong, the subs, called “golden fish,” could travel at 44 knots, or 50 miles per hour, underwater.

This history allowed Boeing to be assured of a stable Russian supply. Besides Russia and other former Soviet states, only four countries smelt it in industrial quantities: the United States, Germany, Japan and China.

That cold war experience gave Avisma knowledge and astounding capacity. It once produced 90,000 tons a year, more than the rest of the world combined in the 1970s. The factory now makes about 32,000 tons, though of a higher grade. Over all, Avisma produces 45 percent of the world’s aerospace titanium.
