C63000 AMS 4640 Nickel Aluminum Bronze

C63000 Nickel Aluminum Bronze is an extruded aluminum bronze that contains nickel, and is alloyed for exceptional strength and toughness. It's used where higher mechanical properties are required. It's used in equipment for the energy markets, in aircraft, marine and a host of other industrial applications. It finds use as valve stems, high strength bushings, valve guides and seats, gears, cams, ship propellers, as well as propeller nuts and shafts. This high strength alloy is comparable to medium carbon steel. It posses good anti frictional characteristics and resists scaling and oxidation at elevated temperatures. Also known as AMS 4640 this alloy is an excellent choice for applications involving heavy loads, abrasive wear resistance, friction, and corrosion.

Cut to Size Bar Stock - What It Means, and How It Benefits You

We use the term “cut to size” in a number of places on this site. But what are we actually talking about when we use this term? Cut to size bar stock means that we will cut your bar stock to the exact length you require. We don’t force you to buy any standard lengths or minimum purchase. In laymen’s terms, you only buy the material that you
