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