Description
Technical field
The present invention relates to non-ferrous metal technical field, be specifically related to a kind of pen core wear-resistant copper alloy material and preparation method thereof.
Background technology
Copper alloy with fine copper for matrix adds the alloy that one or more other elements form.Fine copper is red-purple, also known as red copper.Fine copper density is 8.96, and fusing point is 1083 DEG C, has excellent electroconductibility, thermal conductivity, ductility and solidity to corrosion.Be mainly used in making the heat conduction equipment such as flat plate collector of the electrical material such as generator, bus, cable, switching arrangement, transformer and heat exchanger, pipeline, solar heat collector.Conventional copper alloy is divided into the large class of brass, bronze, copper-nickel alloy 3.
Copper-nickel alloy take nickel as the copper alloy of main adding elements.Copper nickel binary alloy claims common copper-nickel alloy; The White brass alloy being added with the elements such as manganese, iron, zinc, aluminium claims complicated copper-nickel alloy.Industrial copper-nickel alloy is divided into structure copper-nickel alloy and the large class of electrician's copper-nickel alloy two.The feature of structure copper-nickel alloy is that mechanical property and solidity to corrosion are good, and color and luster is attractive in appearance.This copper-nickel alloy extensively manufactures precision optical machinery, glasses accessory, chemical machinery and ship structural component with what.Electrician's copper-nickel alloy generally has good thermoelectricity capability.Copper-manganese, constantan, to examine copper be the different manganese-copper of manganese content, is the material manufacturing accurate electric instrument, varistor, precision resistance, foil gauge, thermopair etc.
The alloy that brass is made up of copper and zinc.If the brass be just made up of copper, zinc is just called market brass.Brass is often used to manufacture valve, water pipe, air-conditioning connection pipe for internal-external unit and scatterer etc.
Bronze is the alloy that China uses the earliest, so far the history of existing more than 3,000 year.The former finger gunmetal of bronze, the copper alloy afterwards except brass, copper-nickel alloy all claims bronze, and titled with the name of the first main adding elements before bronze name of being everlasting.Good and the good mechanical property of the castability of tinbronze, antifriction performance, is applicable to what and manufactures bearing, worm gear, gear etc.
Fine copper, high-quality red metal purity is high, organizes fine and closely woven, and oxygen level is extremely low.Pore-free, trachoma, loose, conductivity is splendid, and be applicable to electrograving mould, through thermal treatment process, electrode is non-directional, is applicable to essence and beats, carefully beat.
Copper is the preferred material of pen core, pen core material copper alloy will meet wear-resisting, corrosion resistant performance requriements, general employing cupronickel alloy material, and the material of cupronickel alloy material due to add micronutrient levels cause more greatly production cost higher, thus cause system an industry customer material cost higher.If directly select fine copper or brass and bronze, the mechanical property of the excellence of system required by an industry, easily turning, easily punching, good abrasion resistance properties, good corrosion resistance can not be met again.
