Abstract
The corrosion-resistant alloy H70 comprises 68.5-71.5% Cu, 0.01-0.2% Sn or 0.01-0.07% P as microelement, and Zn. The copper strap is manufactured by: designing alloy, preparing, level continuous casting, milling surface, coarse rolling, intermediate annealing, precise rolling, shearing, and packing. This product has can be used to vehicle radiator and cooling pipe to avoid pollution fresh water and prolong service time.
Description
(1) technical field under
The present invention relates to a kind of alloy, the making method of particularly a kind of corrosion alloy brass H70 and copper strips thereof.
(2) background technology
At present, brass H70 is made up of the zinc of 68.5～71.5%Cu and surplus, belongs to common Mock platina.Dezincification corrosion very easily takes place in common Mock platina, along with constantly riseing of copper valency, is to reduce manufacturing cost, and the used thickness of copper strips is also at continuous attenuate, and this has had a strong impact on the work-ing life of subsequent product.
(3) content of the present invention
The present invention is in order to remedy the deficiencies in the prior art, provides a kind of and have better erosion resistance, improved the corrosion alloy brass H70 in work-ing life of product and the making method of copper strips thereof.
The present invention is achieved through the following technical solutions:
A kind of corrosion alloy brass H70, its special character is: be made up of following components in weight percentage: copper: 68.5～71.5%; Trace element: tin 0.01～0.2% and/or phosphorus 0.01～0.07%; Surplus is a zinc.
Corrosion alloy brass H70 of the present invention, described trace element are tin, and weight percent is 0.01～0.2%.
Corrosion alloy brass H70 of the present invention, described trace element are phosphorus, and weight percent is 0.01～0.07%.
Corrosion alloy brass H70 of the present invention, described trace element are tin 0.01～0.2% and phosphorus 0.01～0.07%.
The making method of corrosion alloy brass H70 copper strips of the present invention can adopt following concrete steps: alloy designs → batching → horizontal casting → mill face → roughing → process annealing → finish rolling → shearing, pack.
The making method of corrosion alloy brass H70 copper strips of the present invention also can adopt following concrete steps: alloy designs → batching → D.C.casting → hot rolling → mill face → roughing → process annealing → finish rolling → shearing, pack.
The present invention is on the basis of market brass H70, reaches the corrosion resistance nature that improves alloy by adding micro-tin, phosphorus.Tin element and phosphoric can exist simultaneously, but also Individual existence.
The present invention is mainly used in and makes the automobile radiators cooling tube, and the market brass H70 of the common usefulness of this alloy ratio has better erosion resistance, can avoid polluting fresh water environment, has improved the work-ing life of product greatly.
