Description
Technical field
The present invention relates to technical field of metal, be specifically related to a kind of corrosion-resistant copper molybdenum evanohm.
Background technology
Copper alloy adds, by matrix, the alloy that one or more other elements are constituted with fine copper.Fine copper is purple
Red also known as red copper.Fine copper density is that 8.96 fusing points are 1083 DEG C and have excellent electric conductivity and lead
Hot ductility and corrosion resistance.It is mainly used in making generator bus cable switch device to become
The heat transfer devices such as the flat plate collector of the electrotechnical apparatus such as depressor and heat-exchanger pipeline solar heat collector
Material.Conventional copper alloy is divided into the big class of yellow metal copper-nickel alloy 3.
Brass makees the copper alloy of main adding elements with zinc, has yellow attractive in appearance, is referred to as brass.Copper zinc
Bianry alloy claims basis brass or claims simple brass.Brass more than ternary claims special brass or claims complicated yellow
Copper.Brass alloys containing the low what of zinc 36% are made up of solid solution, have good cold-forming property, as containing zinc
The brass of 30% is commonly used to make shell case, is commonly called as cartridge brass or carobrozne.Containing zinc between 36～42%
Brass alloys formed by with solid solution, most common of which is six or four brass containing zinc 40%.In order to improve
The performance of basis brass, often adds other elements, such as aluminium nickel manganese tin silicon lead etc..Aluminium can carry
The intensity hardness of high brass and corrosion resistance, but make plasticity reduce, it is suitable as seagoing vessel condenser pipe and other are resistance to
Erosion part.Tin can improve the intensity of brass and the rotproofness to seawater, therefore claims admirality brass, as boats and ships
Thermal Equipment and screw etc..Lead can improve the cutting ability of brass；This free-cutting brass is commonly used for clock
Table part.Brassing is commonly used to make valve and pipe fitting etc..The fire hydrant explosion-proof moon that boats and ships are conventional
Tooth spanner, it is simply that brass adds aluminum casting and forms.
Current brass alloys kind is many, but its quality or environmental-protecting performance sometimes differ and meet requirement surely,
Such as, ledrite is widely used in the decay resistance of its excellence, free cutting property and processability
