In the manner, the aluminum magnesium alloy disclosed by the invention is firm in quality, light in weight, low in density, good in heat dissipation, and strong in tensile strength; especially, the creep resistance and the high-temperature fatigue resistance are improved. The aluminum magnesium alloy is used as a novel automobile material, so that the weight of an automobile can be reduced, and the tailpipe emission of the automobile is also reduced.
Description
Technical field
The present invention relates to metal alloy compositions field, particularly relate to a kind of aluminum magnesium alloy.
Background technology
Energy-conservation, safety, environmental protection have become three large themes of automobile industry development, and automotive industry has proposed to alleviate vehicle weight, reduces fuel oil consumption, improved the requirements such as structural strength.The lightweight of automobile has become the trend of automobile industry development in world wide, need a kind of new automobile material for the production of lightweight, oil consumption is few, meet the young mobile of environmental requirement.
The hard amount of aluminum magnesium alloy matter is light, density is low, thermal diffusivity is better, crushing resistance is stronger, can fully meet automobile industry requirement.Its hardness is the several times of conventional plastic, but weight is only the latter's 1/3rd.Adopting hydronalium is one of effective measure that reduce motor vehicle emission, raising fuel economy.
Fast development along with automobile industry, new automobile materials of aluminum magnesium alloy has also obtained further popularization and development, but restriction aluminum magnesium alloy development a high-temperature behavior that major cause is aluminum magnesium alloy---creep resisting ability and high temperature fatigue ability are poor, therefore, existing aluminum magnesium alloy is optimized, particularly aluminum magnesium alloy is carried out to modification, by adding alloying element to improve the high-temperature behavior of alloy, prepare a kind of aluminum magnesium alloy of high comprehensive performance and replace orthodox car material, as iron and steel, the usage quantity of non-ferrous metal, become the trend of new automobile Materials.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of aluminum magnesium alloy, the hard amount of matter is light, density is low, thermal diffusivity is better, crushing resistance is stronger, especially its creep resisting ability and high temperature fatigue ability have been improved, as new automobile materials'use, can alleviate vehicle weight, reduce automobile emission amount.
