Abstract
The invention provides high strength tin brass, and relates to the field of copper alloy. The high strength tin brass is characterized by comprising, by weight, copper 65.0 to 69.0% and tin 0.3 to 1.8%, with the balance being zinc and unavoidable impurities with a total amount no more than 0.3%, and by being prepared by melting and rolling. According to the invention, a third element tin is added on the basis of common Cu-Zn brass to improve strength and elasticity of alloy and dezincification corrosion resistance of copper alloy in marine environment; after processed, tin brass has mechanical and chemical properties similar to those of phosphor bronze and finished products of tin brass have excellent elongation percentage, thereby saving copper resources and obtaining high cost performance. The high strength tin brass provided in the invention is widely applicable to socket connectors, springs, connectors, switches, contacts and the like of electronic equipment and to various copper alloy parts used in a marine corrosive environment.
Description
Affiliated technical field
The present invention relates to the copper alloy field, relate to a kind of high strength one-ton brass particularly.
Background technology
At present, the material of making various conductive elastic components such as electronic apparatus connector, spring, junctor, switch, contact is mainly tin-phosphor bronze, the tin-phosphor bronze material has defectives such as cast condition negative segregation, and production cost height, copper loss in order to reduce material cost and copper resource consumption, uses brass to replace tin-phosphor bronze extensively to be proposed with bigger, can can't substitute tin-phosphor bronze owing to the intensity and the elasticity of market brass are lower than the tin-phosphor bronze.
Summary of the invention
The objective of the invention is in order to remedy the deficiencies in the prior art, a kind of high strength one-ton brass that better intensity can partly substitute tin-phosphor bronze that has is provided.
The present invention realizes by the following technical solutions.The composition that it is characterized in that each component is respectively by weight percentage: copper 65.0～69.0%, and tin 0.3～1.8%, surplus is that zinc and total amount are not more than 0.3% unavoidable impurities; Through melting, rolling making.
The composition that it is characterized in that each component is respectively by weight percentage: copper 66.5%, and tin 0.7%, surplus is that zinc and total amount are not more than 0.3% unavoidable impurities; Through melting, rolling making.
The composition that it is characterized in that each component is respectively by weight percentage: copper 67.5%, and tin 1.2%, surplus is that zinc and total amount are not more than 0.3% unavoidable impurities; Through melting, rolling making.
The composition that it is characterized in that each component is respectively by weight percentage: copper 68.5%, and tin 1.5%, surplus is that zinc and total amount are not more than 0.3% unavoidable impurities; Through melting, rolling making.
Positively effect of the present invention is: on common Cu-Zn brass basis, by adding intensity and the elastic performance that the third element tin improves alloy, tin-phosphor bronze physicals with same condition is suitable on tensile strength and Young's modulus after processing, also comparatively satisfied for the unit elongation that portioned product requires, can partly substitute tin-phosphor bronze; Copper content of the present invention (weight percent) is 65.0～69.0%, the tin-phosphor bronze copper content (weight percent) of the usage quantity of comparing maximum is more than 93.0%, the minimum minimizing 24.0% of copper resource consumption can be saved domestic scarce resource metallic copper greatly, and cost performance is higher; The present invention is widely used in each Albatra metal-part of making electronic apparatus connector, spring, junctor, switch, contact etc. and using under the marine corrosion environment.
