High-Performance Aluminum‑Nickel‑Bronze TQ50 Tube – C95520 Alloy

Materion Performance Alloy C95520 is an Aluminum-Nickel-Bronze alloys that combine high strength, ductility, and good abrasion resistance under severe loading conditions. Materion uses the EquaCast® process to produce C95520. This process produces an extremely uniform, fine grained microstructure and excellent dispersion of alloying elements, providing improved product consistency, quality and machinability.
