All copper alloy castings of Shenyang Gongda meet the industry standardPosted by wearresistant William on April 23rd, 2019 Our foundry has been casting copper based alloy since its conception as a casting producer as far back as decades. All alloys are sand cast using either the green sand or air set process. All Copper Alloy Castings conform to BS1400. Phosphor bronze Pb1, Pb2, Pb3 Generally used for bearings, gear wheels, springs and general coppersmithing. Leaded phosphor bronze Lpb1 This being a leaded phosphor bronze it is suitable for a wide range of bearings. It can also be used for valves, high-pressure steam fittings, general duty bushes. Gunmetal G1 A composition with good resistance to corrosion, which is also standard admiralty gunmetal. It can be used for high load, low speed bearings, high-pressure pipefittings, and also a certain amount of hydraulic castings. Leaded Gunmetal LG2 A material with excellent machining characteristics, good casting qualities and moderate strength. Particularly suitable where pressure tightness is required. Leaded Gunmetal LG4 When cast is not so sensitive to changes in section as LG2 and is also suitable where thick wall sections are incorporated. Is often used for high-pressure valves where liquid oxygen and nitrogen are present. Hydraulic pressure and centrifugal pump castings. Aluminium Bronze AB2 Has excellent bio fouling resistance and corrosion resistance. Used for acid resisting pump parts and marine use. High Tensile Brass HTB3 A high tensile brass with good corrosion resistance but is liable to stress corrosion cracking when used in marine and salt-water conditions. It is mainly used for large nuts and similar threaded components. If you want to know more information, you can click here: Alloy Steel Castings. Like it? Share it! More by this author |
