DWA is a manufacturer of metal matrix composites (MMCs) reinforced with silicon carbide particles. Their materials have been used by American aircraft manufacturers, aircraft engine manufactures, in addition to the U.S. Army, and more recently, in European automotive industries.

Characteristics of DWA Products

DWA products are suited for optimizing the development of parts that need to be lightweight with great strength and stiffness. For the parts currently made of aluminum, the use of MMCs can improve strength while maintaining the light weight of aluminum. For the parts currently made of stainless steel, the use of MMCs can reduce the weight (reduction to 40% max.) while achieving the same level of stiffness as titanium. In addition, the parts can be expected to have longer service life due to higher fuel efficiency enabled by the reduced weight, and higher fatigue resistance enabled by the reduced coefficient of thermal expansion. DWA products have been used for key automobile components after having passed the strict impact resistance test conducted by European automobile manufacturers.

When the Boeing Company needed a better corrosion protectant and waterproof lubricant, they developed Boeshield T-9R.

BOESHIELD T-9

Forty years ago, the world’s largest aerospace builder?The Boeing Company?needed access to a more reliable metal protectant/lubricant that could withstand long exposure to a corrosive environment.
Their research revealed that Teflon, silicone and synthetic sprays were all inadequate for the task, so they developed a better product of their own. The result was Boeshield T-9R, the only product of its type to be licensed by The Boeing Company.
T-9’s unique formulation of solvents and waxes was engineered to penetrate metal crevices deeply, displace moisture, dissolve minor corrosion, and leave a clean, waxy coating with long-lasting durability.
