Los Angeles, CA-- May 15, 2006—Material Technologies, Inc. (OTC BB; MTNA.OB - News) ("MATECH") announced that it has installed and tested its revolutionary metal fatigue detection solutions at the American Association of Railroads’ (AAR) Transportation Technology Center (TTC). MATECH demonstrated the ability of its patented Electrochemical Fatigue Sensor™ (EFS) to accurately measure microscopic growing cracks and metal fatigue in railway bridges, track, and other equipment.

The Transportation Technology Center, a subsidiary of the AAR, is a world class facility offering unique capabilities for research, development, testing, and training for railway-related technologies. The site, 21 miles northeast of Pueblo, Colorado, is owned by the US Department of Transportation and is operated and maintained by the TTC, under contract with the Federal Railroad Administration (FRA). TTC’s 52 square mile testing center contains more than 48 miles of specialized railroad test tracks and facilities, and enables testing of all types of freight and passenger rolling stock, vehicle and track components, and safety devices. Its laboratories house sophisticated test equipment to answer questions regarding fatigue, durability, safety, ride comfort and truck suspension.

“The $286 billion U.S. Transportation Bill requires each railway track operator using continuous welded rail track to include procedures to improve the identification of cracks as well as improve inspection methods for joint bars in continuous welded rail,” said MATECH CEO Robert M. Bernstein. “Our EFS nondestructive testing system can detect growing cracks as small as 0.010 inches. We demonstrated our EFS’s ability to detect these types of cracks at TTC, and expect to see excellent results. We are especially delighted that our testing revealed that the EFS was shown, in a side-by-side comparison, to identify growing cracks that other techniques could not.”

According to a recent report published by the AAR, major freight railroads will spend more than $8.2 billion in 2006 laying new track, buying new equipment and improving infrastructure. MATECH’s EFS technology can help ensure the integrity of metal structures and equipment, enabling railway engineers to improve safety, optimize repairs and reduce costs.
