Abstract
The invention relates to a copper-magnesium alloy material. The copper-magnesium alloy material comprises, by weight, 29%-46% of Mg, 0.07%-0.12% of Ge, 0.38%-0.42% of Sc, 0.55%-0.59% of Be, 0.05%-0.09% of Nd, and the balance Cu. The obtained copper-magnesium alloy material has the quite high electrical conductivity.
Description
Technical field
The present invention relates to a kind of alloy material, particularly relate to a kind of Copper-magnesium alloy material.
Background technology
Alloy material is in the middle of use procedure, and the electric conductivity of alloy material is extremely important.Relate to circuit at some to connect and in electrical wiring, the size of electric conductivity directly left and right the effect of product and the quality of signal.How can improve the electric conductivity of copper alloy, be a focus of the industry research, the electric conductivity of usual some other alloy material only has 30% to 40% always, the serious normal operation affecting related products.Therefore we are necessary to find a kind of Cu alloy material with very high electric conductivity very much, promote the conductivity of copper product.
Summary of the invention
The technical problem solved: the problem that common copper alloy material electric conductivity is lower.
Technical scheme: the invention discloses a kind of Copper-magnesium alloy material, Copper-magnesium alloy material consists of the following composition: Mg is 29wt% ~ 46wt%, Ge be 0.07wt% ~ 0.12wt%, Sc be 0.38wt% ~ 0.42wt%, Be be 0.55wt% ~ 0.59wt%, Nd is 0.05wt% ~ 0.09wt%, surplus is Cu.
Copper-magnesium alloy material preparation process is as follows: get required each chemical composition, wherein: Mg is 29wt% ~ 46wt%, Ge be 0.07wt% ~ 0.12wt%, Sc be 0.38wt% ~ 0.42wt%, Be be 0.55wt% ~ 0.59wt%, Nd is 0.05wt% ~ 0.09wt%, surplus is Cu.All the components being dropped into induction melts in furnace, smelts, Heating temperature to 960 DEG C, melts evenly and is rolled into copper magnesium rod, then temperature is set as 650 DEG C keep 10h, are finally reduced to room temperature by temperature, prepare Copper-magnesium alloy material.
Beneficial effect: the Copper-magnesium alloy material prepared has very high electric conductivity.The electric conductivity of Copper-magnesium alloy material is 62% ~ 68%IACS.There is very excellent conductive effect, can extensively apply in the use of related products.
