Description
Technical field
The present invention relates to technical field of metal, be specifically related to a kind of antioxidant silicon phosphorus pyrite.
Background technology
Pyrite makees the copper alloy of main adding elements with zinc, has yellow attractive in appearance, is referred to as pyrite.Copper zinc
Bianry alloy claims basis brass or claims simple pyrite.Pyrite 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 pyrite 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 pyrite containing zinc 40%.In order to improve
The performance of basis brass, often adds other elements, such as aluminum nickel manganese stannum silicon lead etc..Aluminum can carry
The intensity hardness of high pyrite and corrosion resistance, but make plasticity reduce, it is suitable as seagoing vessel condensing tube and other are resistance to
Erosion part.Stannum can improve the intensity of pyrite and the rotproofness to sea water, therefore claims admirality brass, as boats and ships
Thermal Equipment and propeller etc..Lead can improve the cutting ability of pyrite；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 pyrite adds aluminum casting and forms.
Silicon phosphorus pyrite is mainly addition silicon, P elements in pyrite so that brass alloys mechanical property is more preferable.
But at present, silicon phosphorus pyrite is corrosion-resistant, antioxidation, shock resistance are general, it is impossible to some of adaptation market
Demand.
