Aluminum alloy die-casting products are widely used in industries such as electronics, automotive, motors, home appliances, and others. Some high-precision and high-tensile aluminum alloy die-casting products are also utilized in industries with high technical requirements, such as large machinery and shipbuilding. Aluminum alloy die-casting parts 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 leaded brass, and can be seamlessly integrated with existing brass processing techniques. The blanks require no special treatment and can be directly electroplated or passivated.
2. Qingdao Aluminum Alloy Castings Offer Excellent Surface Treatment: 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 pitting and bubbles, with a surface finish that is very similar to that of copper-plated products. Neutral salt spray testing for 48 hours shows no significant corrosion, 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 brasses. 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 fast-cut extruded zinc aluminum alloy materials, the cost of a finished product is only 40% of that of lead brass. In the harsh economic environment of 2009, widespread application of fast-cut extruded zinc aluminum alloy alleviated the financial pressure of enterprises and enhanced the overall competitiveness of the products.
