Description
Technical field:
The present invention relates to copper alloy, particularly a kind of high conductivity copper-magnesium alloy for automobile electrical equipment.
Background technology:
For a long time, copper can be by improving intensity with the alloy of different elements.Except individual cases, additive has disproportionately reduced specific conductivity when having increased intensity.The peak value tensile strength is about 421.86 * 10
5Kg/m
2Fine copper (60ksi) has the electric conductivity of 100%IACS.Therefore, the coefficient of the intensity * specific conductivity of fine copper is 6,000 (60 * 100) unit.As a kind of ancient copper alloy, the intensity of brass is up to 731.22 * 10
5Kg/m
2(104ksi), but specific conductivity sharply reduce.Cartridge brass is a kind of the most frequently used brass, and the coefficient of its intensity * specific conductivity is lower than 3,000 units.Intensity * electric conductivity the coefficient of other alloy such as bronze and copper-nickel alloy is far below fine copper.
Japanese Patent 53-19920 relates to an Albatra metal-, and it contains 0.04-0.04% phosphorus, the magnesium of one or more of 0.01-0.20%, silicon, manganese, arsenic and zinc, and surplus copper.This type of alloy has the 80-90%IACS specific conductivity, but its hardness is lower.
United States Patent (USP) 4,605,532 disclose a kind of alloy, its composition is as follows substantially: the iron of about 0.3-1.6 weight %, at most the iron level of half by nickel, manganese, cobalt with and composition thereof replace the magnesium of month 0.01-0.2 weight %, the phosphorus of about 0.10-0.40 weight %, the highest about 0.5 weight % tin or antimony with and composition thereof and the copper of surplus.This alloy is based on high phosphorus magnesium ratio, and it was at least 1.5: 1, and preferably is higher than 2.5: 1.Its result is exactly that although all magnesium in the alloy all will combine with phosphorus, other element that resembles iron and cobalt will be stayed in the solution in a large number.Therefore electric conductivity will suffer damage.Alloy also contains the coarse particles of 1-3 micron.Therefore, alloy ductility, formability, softening resistance are relatively poor, and intensity * specific conductivity coefficient is low.
Summary of the invention:
The objective of the invention is to provide a kind of high conductivity copper-magnesium alloy for automobile electrical equipment, can overcome the defective in the above-mentioned prior art products.
For solving the problems of the technologies described above, the present invention is achieved in that
A kind of high conductivity copper-magnesium alloy for automobile electrical equipment adds trace alloying element magnesium and phosphorus in fine copper, it is characterized in that: according to weight percent, contain 0.001-0.1% phosphorus in the product, and 0.4-0.8% magnesium, surplus is a copper.
The correlation technique parameter of this copper-magnesium alloy is: tensile strength Ra:460MPa-520MPa, elongation A
