Abstract
The invention relates to the field of aluminum-based alloy taking silicon as secondary active ingredient, and particularly relates to a die-cast aluminum alloy for an automobile engine. The die-cast aluminum alloy for the automobile engine comprises Al and Si, wherein the mass percentage of Si is 5%-15%, the die-cast aluminum alloy is characterized by further comprising the following elements in percentage by mass: 0.5%-0.8% of Mn, 0.25%-0.35% of Mg, 0.04%-0.15% of Ti, 0.01%-0.022% of Sr, and the balance of Al. The die-cast aluminum alloy is good in die-cast property, low in rejection rate, and high in mechanical property.
Description
Technical field
The present invention relates to silicon and do the field, aluminum base alloy field of time main component, be specially a kind of aluminium diecast alloy for motor car engine.
Background technology
At aviation, automobile manufacturing field, because needs reduce component weight as far as possible with the fuel-efficient consumption that subtracts, density is low, the good aluminium alloy of heat conductivity thus obtain widespread use.Taking the oil pan part of automobile as example, oil pan is lower part of vehicle crankcase, be called again lower crankcase, effect is the shell of sealing crankcase as oil cistern, prevent that impurity from entering, and collect and store the lubricating oil being flowed back to by the each friction surface of diesel engine, non-dramatic song part heat, prevents oil ageing.Oil pan is typical box parts, wall is thin and complex-shaped, many employing high-pressure castings at present, but owing to being subject to the restriction of aluminium alloy capability, be difficult to reach the requirement that has high ductibility, elongation is only generally 1%～3%, for avoiding bottom cause engine oil leakage because accidental impact cracks and the situation such as kill, the following two kinds of methods of normal employing at present: 1. oil pan adopts split-type structural, and make with aluminium alloy on top, bottom adopts higher soft steel or the wrought iron of ductility to make; 2. high-frequency quenching softening processing are implemented in the bottom of pair oil pan.These measures can improve the ductility of oil pan bottom, and still, the 1st kind of method can cause engine weight to increase, the 2nd kind of method complex operation, and qualification rate is not high.
Summary of the invention
In order to overcome the defect of prior art, the aluminium alloy that a kind of mechanical property is high, ductility is strong is provided, the invention discloses a kind of aluminium diecast alloy for motor car engine.
The present invention reaches goal of the invention by following technical solution:
For an aluminium diecast alloy for motor car engine, comprise Al and Si, the mass percent of Si is 5%～15%, it is characterized in that: also comprise Mn, Mg, Ti and Sr, the mass percent of each element is respectively:
Mn:0.5%～0.8%, Mg:0.25%～0.35%, Ti:0.04%～0.15%, Sr:0.01%～0.022%, Al: surplus.
The described aluminium diecast alloy for motor car engine, is characterized in that: also comprise Fe, Zu and Cu, the mass percent of each element is respectively:
Fe :≤0.13%; Zn :≤0.07%; Cu :≤0.03%; The mass percent of other impurity is all not more than 0.05%.
The described aluminium diecast alloy for motor car engine, is characterized in that: the mass percent of Si is 10%; The mass percent of Mg is 0.30%.
The present invention is WT-01 type, and mechanical performance index is: tensile strength >=280MPa; Yield strength >=180MPa; HB hardness >=76(5/250); Unit elongation 5.0%～12%.
The invention has the beneficial effects as follows: pressure die casting performance is good, for engine manufacture, both can alleviate the weight of engine, do not need again the processing of local high-frequency quench annealing, when die casting, scrap rate is low, be the novel die-casting material of high-quality, can meet the user demand of new automobile to high strength vehicle body, structural part, engine part.
