Nickel Alumimium Bronze - Solid Bar AMS 4881. The additional heat treating process improves mechanical properties and the strength to weight ratio exceeding the range of typical aluminum bronzes. UNS C99520 is commonly used in applications involving heavy loads abrasion,friction, and deformation at high temperatures. In many cases UNS C99520 can replace UNS C63020 with the advantage of this material being available in tube form, which provides economic cost savings to you the customer.
