Aluminum alloy die-casting products are widely used in industries such as electronics, automotive, motors, and home appliances. Some high-precision and high-toughness aluminum alloy die-casting products are also utilized 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 high-speed 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 cutting depths, 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 machining efficiency exceeding 75% of lead brass, allowing for seamless alignment with existing brass processing techniques. The blanks require no special treatment and can be directly plated or passivated.
2. Qingdao aluminum alloy casting surface treatment offers excellent results: zinc aluminum alloy die casting is suitable for various electroplating processes, including copper plating, nickel plating, chrome plating, tin plating, silver plating, and ternary alloy plating. The finished parts are free of asperities and bubbles, with a surface finish very similar to that of copper-plated products. Neutral salt spray testing shows no obvious corrosion after 48 hours, and the electroplating yield can reach above 98%.
3. Excellent Conductivity: The conductivity is similar to H62, with a conductivity greater than 28% (IACS), surpassing common H59 brass and zinc aluminum alloy die casting has broad application prospects in the electronics, electrical, and electrical industries.
4. High cost-performance ratio: Material cost is about 60% of HPb59-1, and material density is about 70% of HPb59-1. Using quick-cut extruded zinc aluminum alloy materials, the cost of a finished product is only 40% of the cost of lead brass. In 2009's adverse economic environment, widely promoting the application of quick-cut extruded zinc aluminum alloy helped alleviate the financial pressure on enterprises and enhance the comprehensive competitiveness of the products.
