Problems solved by technology

[0003] However, since the ADC12 has poor corrosion resistance, when it is used in a corrosive environment, anodizing treatment or other treatment to improve corrosion resistance is required, which may cause problems in terms of labor and cost.
[0004] In contrast, ADC5 and ADC6 (hereinafter referred to as "ADC5" and "ADC6"), which are Al-Mg alloys for die-casting specified in JIS H5302, are excellent in corrosion resistance, but have poor fluidity due to their wide solidification range. Cracks are prone to occur in die-cast products
In other words, Al-Mg-based die-casting alloys are significantly inferior in castability compared to ADC12, so there is a problem that its use is often limited to simple product shapes

Embodiment

[0045] Hereinafter, although an Example is given and this invention is demonstrated concretely, this invention is not limited to an Example.

[0046] In addition, each mechanical characteristic (tensile strength, elongation, 0.2% yield strength) in the predetermined Example and the comparative example was measured by the following method. That is, using a common die-casting machine (manufactured by Toshiba Machinery Co., Ltd., DC135EL) with a clamping force of 135 tons, die-casting was performed at an injection speed of 1.0 m / sec and a casting pressure of 60 MPa, and an ASTM (American Society for Testing and Material) was produced. ) standard as the reference round bar specimen. Then, the tensile strength, elongation, and 0.2% yield strength were measured for the round bar sample pieces in the as-cast state using a universal testing machine (AG-IS 100 kN) manufactured by Shimadzu Corporation.

[0047] In addition, the corrosion resistance was evaluated by a (neutral) salt spr...

Abstract

Provided are an aluminum alloy for die casting having casting properties and mechanical characteristics equal to those of ADC12 and having corrosion resistance equal to that of ADC6, and an aluminum alloy die-cast product die-cast from the alloy. Specifically, this aluminum alloy for die casting is characterized by comprising no more than 0.10 wt% Cu, 12.0-15.0 wt% Si, no more than 1.00 wt% Mg, 0.05-1.00 wt% Fe, and 0.10-0.50 wt% Cr, the remainder comprising Al and unavoidable impurities.

Description

technical field [0001] The present invention relates to an aluminum alloy for die-casting with improved castability and corrosion resistance, and an aluminum alloy die-cast product using the alloy. Background technique [0002] Aluminum alloy is lightweight and has many properties such as excellent thermal conductivity and high corrosion resistance, so it is widely used as a raw material for its components in automobiles, industrial machinery, aircraft, home appliances, and various other fields. One of them is the field of die-casting aluminum alloys. As a representative aluminum alloy, there is ADC12 (hereinafter simply referred to as "ADC12"), an Al-Si-Cu-based die-casting alloy specified by Japanese Industrial Standard JISH5302. Since ADC12 has good fluidity and filling properties during casting (die casting), it is often used for covers and housings such as carburetors, cylinder blocks, and cylinder head covers of automobiles, or die-cast parts other than automobiles. ...
