Abstract
The invention discloses an aluminum casting high in elongation and tensile strength. The aluminum casting mainly comprises, by weight percent, 0.0001-0.005% of tin, 0.003-0.08% of cobalt, 0.005-0.1% of nickel, 0.05-2.5% of bismuth, 0.6-7.5% of metalloid, 0.007-0.8% of rare metals, and the balance of aluminum and impurities. The aluminum casting is high in tensile strength or elongation and is high-quality aluminum casting material satisfying the requirements of different working conditions for aluminum casting properties.
Description
Technical field
The present invention relates to the foundry goods field, particularly relate to the aluminium casting of a kind of high elongation rate and tensile strength.
Background technology
The content of aluminium element in the earth's crust is only second to oxygen and silicon, occupies the 3rd, is the abundantest metallic element of content in the earth's crust.Along with the development of science and technology, the aluminium of high quality, high-tech content is developed, and the elongation of hard attitude fine aluminium is very low, shows that aluminium casting is exactly that its snappiness is very poor on using; The elongation of soft attitude fine aluminium significantly improves than hard attitude fine aluminium, but its elongation is not high, and fine aluminium can not satisfy now have been used in aluminium casting.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of possess good tensile strength or extensibility, can satisfy now the high elongation rate of the requirement of aluminium casting and the aluminium casting of tensile strength.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the aluminium casting that a kind of high elongation rate and tensile strength are provided, it mainly is comprised of aluminium, tin, cobalt, nickel, bismuth, metalloid and rare metal, and the weight percentage of described each component is as follows:
Tin 0.0001-0.005%,
Cobalt 0.003-0.08%,
Nickel 0.005-0.1%,
Bismuth 0.05-2.5%,
Metalloid 0.6-7.5%,
Rare metal 0.007-0.8%,
Surplus is aluminium and impurity.
In a preferred embodiment of the present invention, described metalloid is boron, silicon or tellurium.
In a preferred embodiment of the present invention, described rare metal is gallium, indium, thallium or germanium.
In a preferred embodiment of the present invention, described metalloid content is 1.0-5.0%.
In a preferred embodiment of the present invention, the content of described rare metal is 0.01-0.3%.
The invention has the beneficial effects as follows: the present invention possesses good tensile strength or extensibility, is the aluminium casting material of high-quality, can satisfy different operating modes to the performance requriements of aluminium casting.
