Brass/Bronze / NI-AL-BRZ (630)

NI-AL-BRZ ALLOY C-630 is an extruded aluminum bronze that is alloyed with nickel for added strength and toughness. This material also offers good resistance to sea-water corrosion and oxidation. The alloys high strength, hardness, good fatigue and shock resistance makes it ideal for products that require higher mechanical properties. C-630 is used to make parts for the aerospace industry, energy markets, maritime & naval equipment and a variety of other industrial applications. Common parts manufactured from this alloy include bushings, bearings, screws, valve stems, gears, cams and ship propellers. Copper Alloy UNS # 63000
