AMS-4881 Sand Casted
AMS 4881 Nickel Aluminium Bronze is a material similar to AMS 4880, offered in solid round rod and hollow bar. An additional heat treatment process improves its mechanical properties and strength to weight ratio.
AMS 4881 is commonly used in applications involving heavy loads abrasion, friction, and deformation at high temperatures. In many cases AMS 4881 can replace AMS 4640 with the advantage of this material being available in tube form, which again provides cost savings.
