Abstract
The invention discloses a brine-corrosion-resistant alloy. The alloy comprises the following alloying elements: 4-8% of Ni, 0.5-0.9% of C, 1-2% of Pb, 0.3-0.6% of Cr, and the balance of copper. The alloy has good strength and toughness and the galvanic corrosion effect of the alloy and the copper-nickel alloy can be significantly reduced.
Description
Technical field
The invention belongs to field of alloy material, be specifically related to the alloy of a kind of salt water resistance corrosion.
Background technology
In sea water system, nickelaluminium bronze is widely used because of good corrosion resistance nature, but when the defect of nickelaluminium bronze is to support the use with Alpaka, because both corrosion potentials differ greatly, galvanic effect clearly.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of alloy that can corrode with the matching used salt water resistance of Alpaka.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Salt water resistance corrosion an alloy, alloying element and percentage composition as follows: Ni 4-8, C 0.5-0.9, Pb 1-2, Cr 0.3-0.6, surplus is copper.
This alloy has good intensity and toughness, obviously can reduce the galvanic effect of itself and Alpaka.
