Nut is a kind of fastening parts, and the screw or bolt with more, more than ordinary nut for the internal thread, screw in the bolt fastening artifacts.Inside and outside the teeth nut is mainly used for the transformation of the internal and external screw thread connection with external thread at one end, side with internal thread.More external thread end connecting pipe, threaded pipe fittings or bore diameter internal thread end connecting smaller size pipe, through the internal and external thread can realize the internal and external screw thread connection mode conversion, or diameter reduction.
Copper nut is to use the mass production of copper nut, copper nut is not easy to rust and corrosion, and the advantages of easy thermal conductivity and electrical conductivity is strong, generally used for rust prevention, high temperature, conductive, thermal conductivity, etc. Use of environment, water faucet, valve, electric switch, etc.
My company production of centrifugal casting alloy products mainly include: self-lubricating bearing, centrifugal casting copper sleeve, copper nut, continuous casting of copper rod, copper tube, worm gear and worm, zinc base alloy.
The main applications are: higher-end mining machinery, engineering machinery, hydroelectric power machinery, auto, shipping, petroleum and other machine tools , etc.
Commonly used in casting of copper
|The serial number||alloy||Main features are||With the way|
|H59||Strength, high hardness and low plasticity, corrosion resistance, performance and H62 close;||General machine parts, hot rolling, welding parts;|
|Cutting performance is good, has the good mechanical properties, corrosion resistance, but easy to produce corrosion cracking.||The most commonly used brass material, washers, springs, nuts and mechanical parts;|
|ZCuZn25Al6Fe3Mn3||With high mechanical properties, the casting performance is good, good corrosion resistance||Suitable for high strength, wear-resistant parts, bearing plate, nut, wear-resistant plate, worm gear, rolling mill slider|
|Wear resistant and corrosion resistant performance is good, easy processing, good casting performance and air tightness;||In high load and medium under the sliding velocity of wear-resisting, corrosion resistant parts, liner, piston, clutch, gland and worm gear pump parts.|
|High hardness, excellent wear resistance, not easily get killed phenomenon, good casting and cutting performance, corrosion resistance in the air and water;||Used in high load (below 20 mpa) and high sliding speed (8 m/s) work under the wearing parts, such as connecting rod, bushings, bearings, gears, worm gear, etc.|
|Corrosion resistance, particularly of dilute sulphuric acid, hydrochloric acid and fatty acid;||Structural materials, corrosion resistant, acid accessories and crusher bushing and bearing shell;|
|Lubrication performance, wear resistance and corrosion resistance performance is good, suitable for bimetal casting materials||Surface pressure is high, there is the lateral pressure of the sliding bearing, such as roll, vehicle use bearing, load peaks 60 mpa hit parts, as well as the highest peak 100 mpa bimetallic bearing bush of the internal combustion engine, the piston pin sets, lining, etc.|
|Has high strength and hardness, good wear resistance properties and casting properties, alloy density is high, the corrosion resistance performance is good, wear parts working temperature below 400 ºC, can be welded.||Suitable for manufacturing of heavy machinery with a shaft sleeve, and require high strength, wear resistance, pressure parts, such as bushings, flange, valve, pump body and so on;|
|High resistance to fatigue strength, wear resistance, strong heat resistance under 400 ºC, and the casting performance is good||For important castings, high strength, good corrosion such as bearings, bearing, gear, worm gear, nut|
|Gao Lixue performance, wear resistance, corrosion resistance||Require high strength, wear resistance, corrosion resistant castings, such as collar, nut and worm gear.|
|Gao Lixue performance, wear resistance, and seawater corrosion||Require high strength, wear resistance, corrosion resistant castings, such as gear, shaft sleeve, nut and worm gear|
|Silicon bronze||ZCuZn16Si4||Have higher mechanical and corrosion resistance, compact structure, good air tightness||Water pipe fittings, water pump, the impeller and the pressure of 4.5 Mpa and 250 ºC steam under casting|
