Description
Technical field
The present invention relates to an Albatra metal-, relate in particular to a kind of low cost, high strength, the good aluminum-bronze alloy material of sea water corrosion resistant, belong to the non-ferrous metal technical field.
Background technology
McGill metals has excellent physical chemistry, mechanical property, anticorrosive wear-resistant performance, it is the engineering materials of a class high comprehensive performance, thereby in civilian, military industry, occupy important status, be widely used in structural parts, wearing piece and the corrosion barrier etc. of working in the occasions such as mechanical industry, boats and ships and ocean industry, household electrical appliances industry, petrochemical industry, electrical industry and building industry.
The corrosion resistant material that present countries in the world are used for condenser adopts the copper-nickel alloy that adds the As one-ton brass, adds the As aluminum brass and contain 10% and 30% nickel always, uses titanium alloy and stainless steel in addition.
But continuous deterioration along with seawater quality, the corrosion resistant material of existing condenser can not meet the demands fully, intensity is on the low side, the shortcoming of the poor-performing of anti-the erosion corrosion as now existing with copper alloy, and titanium alloy and stainless steel then exist the serious problem of marine biological polution.In addition, sea water desalting equipment, boats and ships and Coastal Power Plant have an urgent demand to the high strength anti-corrosion copper pipe always.China has developed the HSn70-1A-0.05 one-ton brass that adds Al at present, adds the HAl77-2A-0.5 aluminum brass of Ni and B etc., has also developed the HSn70-1B alloy of the fresh water generation station-service that pollutes simultaneously.U.S. Olin company develops Zn, and (((0.03～0.06wt%) surplus is the nickeliferous arsenical brass of copper to 2.5～3.5wt%)-As to 25～35wt%)-Ni.Japan develops Zn (10～40wt%)-P (0.005～0.07wt%)-Sn (0.05～1.0wt%)-Al (0.05～1.0wt%)-As (0.005～1.0wt%)-Sb (copper alloy of 0.005～1.0wt%), add one or more elements among B, Ni, Co, Cr, Mn, Te, In, Be, the Ti, it adds total amount is 0.005～2.0wt%, and surplus is a copper.Poland non-ferrous metal research institute has developed the aluminum brass that Ni, Cr, Mn improve.
Above-mentioned disclosed copper alloy though can adapt to certain Working environment, for the improvement in performance of copper alloy has been made contribution, with regard to alloy seawater corrosion resistance, anti-erosion corrosion, still exists problem.For example, one-ton brass and aluminum brass exist that intensity is on the low side, the problem of the poor-performing of anti-the erosion corrosion, and this has just limited the flow velocity of seawater in condenser will greatly reduce the efficient of equipment below 3m/s.
(typical case's representative is: C68700 and the tube bank material that uses in briny environment at present mainly contains aluminum brass, its composition is 76～79wt%Cu, 1.8～2.5wt%Al, surplus is Zn), (typical case's representative is one-ton brass: C44300, its composition is 70～73wt%Cu, 0.8～1.2wt%Sn, 0.06wt%Fe, 0.02～0.06As, surplus is Zn), (typical case's representative is Alpaka: C70600, its composition is 9.0～11wt%Ni, 1.0～1.8wt%Fe, 1.0wt%Mn, 1.0wt%Zn, and surplus is Cu; C71500, its composition are 29～33wt%Ni, 0.4～0.7wt%Fe, 1.0wt%Mn, 1.0wt%Zn, and surplus is Cu; C71640), stainless steel (typical case's representative is 1Cr18Ni9Ti, 0Cr18Ni9Ti, 00Cr19Ni10 and 00Cr18Ni12Mo2) and titanium alloy (typical case's representative is TA2) etc.
Limitation and deficiency that above-mentioned described tube bank material uses in corrosive environment of sea water are: aluminum brass and one-ton brass exist that intensity is on the low side, dealloying (dezincify, dealuminzation) and the serious problem of erosion corrosion; There is the comparatively defective of difficulty of cost height, processing in Alpaka; There are the problem that cost is higher, marine biological polution is serious in titanium alloy and stainless steel.
