Alloy: 630 | Material: Bronze | Shape: Bar/Round | Diameter 0.875 Inches | Item Length: 12 Inches Bronze Round Bar 630 contains a high amount of nickel and aluminum, giving it an exceptionally high strength, as well as high wear resistance, corrosion resistance, and ductility. Additionally, 630 maintains its strength even at elevated temperatures and for prolongued periods. It is typically used in aerospace and marine applications such as valve stems, high strength bushings, valve seats and guides, gears, cams, nuts, shafts, and ship propellers. Aluminum bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion. They are also resistant to corrosion in sea water. UNS 36000, CDA 360, C360, Free-Cutting Brass This product weighs 1.98 pounds and meets the following specs: ASTM-B150, AMS-4640
