Aluminum alloy die-casting products are widely used in industries such as electronics, automotive, motors, and home appliances. Some high-precision and high-tensile aluminum alloy die-casting products are also applied in industries with high technical requirements, like large machinery and shipbuilding. Aluminum alloy die-casting pieces offer the following advantages:
1. Excellent Machining Performance: The fast-cutting extruded zinc aluminum alloy is easily machinable by turning, milling, broaching, drilling, etc., and its comprehensive properties are close to leaded brass, earning it the title of "white brass." This alloy can be machined at higher cutting speeds and deeper cuts, with chips that are easy to break, and its tool wear is comparable to 60/40 brass. The finished parts have high surface finish and precision, with a processing efficiency of over 75% of lead brass, allowing for seamless alignment with existing brass processing techniques. There's no need for special treatment of the blanks, which can be directly electroplated or passivated.
2. Qingdao aluminum alloy casting surface treatment offers excellent results: zinc aluminum alloy die casting is compatible with various electroplating processes, including copper, nickel, chrome, tin, silver, and ternary alloys. The finished parts are free of pitting and bubbles, with a surface finish that is very similar to that of copper-plated products. The neutral salt spray test shows no visible corrosion after 48 hours, and the electroplating yield can reach above 98%.
3. Excellent Conductivity: Similar to H62 in conductivity, with a conductivity of >28% (IACS), surpassing common H59 brasses. Zinc aluminum alloy die-casting has a broad application prospect in electronics, electrical engineering, and electrical industries.
4. High Cost-Effectiveness: Material cost is about 60% of HPb59-1, and material density is about 70% of HPb59-1. Using fast-cut extruded zinc aluminum alloy material, the cost of the same finished product is only 40% of the cost of lead brass. In the harsh economic environment of 2009, the widespread application of fast-cut extruded zinc aluminum alloy helped alleviate the financial pressure on enterprises and enhance the overall competitiveness of the product.
