Detailed Product Description

ABOUT PRODUCT

Tungsten heavy Alloy have long been specified for control surface counterbalancesin aircraft and helicopters. Large mass in a small space isrequired to balance and stabilize control surfaces which must operateat high speeds. A savings in total aircraft weight can result from theuse of these materials because the small high density piece requiresless surrounding material to enclose it. In addition, the high strengthof the material permits the part to be located for the most efficientweight effect and therefore uses the minimum amount of material.
