The casting aluminium-silicon alloy for the cylinderbody of the automobile engine comprises Al and Si, and is characterized by comprising the following elements by weight: 8.5%-10% of Si, 0.65%-0.9% of Fe, 2.5%-3.5% of Cu, 0.3%-0.5% of Mn, 0.4%-0.5% of Mg, 0.6%-1.0% of Zn, 0.08%-0.15% of Ti and the balance of Al. The casting aluminium-silicon alloy provided by the invention has good casting performance, good processing performance and low defective index.
Description
Technical field
The present invention relates to silicon and do the aluminum base alloy field of time main component, be specially a kind of cast Al-Si alloy for the Motor Engine Cylinder cylinder body.
Background technology
The cylinder body of motor car engine generally adopts graphitic cast iron or cast alloy iron to cast, and heat conductivility is poor, because cylinder body contacts with high-temperature high-pressure fuel gas for a long time, need to bear very large thermal load and mechanical load, but easily produce the defects such as pore, seepage, distortion.And aluminium alloy is used widely at aviation, automotive field with light, the corrosion resistant characteristic of its quality.The thermal conductivity of aluminium alloy is good, and intensity is high, is conducive to improve compression ratio, and good casting property is lightweight, can reduce oil consumption.But current aluminium alloy, also exist the slow-footed problem of alloy graining, make the porosity caused due to contraction in the casting finished product larger, affect the mechanical property of foundry goods.Aluminum current silicon alloy mechanical performance index is: tensile strength 190MPa, Brinell hardness 82.8(5/250, use the steel ball of diameter 5mm, closes the Brinell hardness number recorded under the test load effect of 250kgf at 2450N), unit elongation 1.5%.
Summary of the invention
In order to overcome the defect of prior art, a kind of cast aluminium alloy that contraction speed is fast, the foundry goods mechanical property is high is provided, the invention discloses a kind of cast Al-Si alloy for the Motor Engine Cylinder cylinder body.
The present invention reaches goal of the invention by following technical solution:
