Aluminum alloy handles and zinc alloy handles are two different types of handles, and when it comes to choosing handles, people often don't know how to make the right choice. So, what are the main differences between aluminum alloy handles and zinc alloy handles?

1. 1. The main difference lies in the cost of die-casting. The die-casting cost for aluminum alloy handles is generally cheaper, while for zinc alloy handles, the cost of molds can be quite significant.

3. 2. In terms of product price, aluminum alloy handles have an advantage. Handles of the same size, made of zinc alloy, weigh more than twice as much as those made of aluminum alloy. Additionally, post-processing such as electroplating is more expensive for zinc alloy handles compared to oxidation. However, if aluminum profiles are used, the cost becomes even cheaper. Aluminum alloy has good plasticity but low strength, although its specific strength is higher. It is suitable for medium structural materials that need to bear heavy loads. Both aluminum alloy and zinc alloy exhibit good corrosion resistance.

   3. Zinc alloy handles have higher hardness and tensile strength compared to aluminum alloy, but there is no absolute boundary. Aluminum alloy has a lower density and significant variation in hardness. It also exhibits good tensile strength. In terms of weight, zinc alloy handles are heavier.

   4. Aluminum alloy handles have better smoothness. Zinc alloy handles are cheaper in terms of equal weight. In fact, due to the higher density of zinc alloy, the price difference between equal volumes of zinc alloy and aluminum alloy is not significant. Compared to high-quality 304 stainless steel and copper, aluminum alloy offers better cost-effectiveness, making it more suitable for ordinary household use. Aluminum alloy is less prone to oxidation, but it is not as hard as zinc alloy. Zinc alloy is prone to oxidation and brittleness over time, which may lead to breakage.

   5. Aluminum alloy has a low density but relatively high strength, approaching or surpassing that of high-quality steel. It has good plasticity and can be processed into various profiles. It also exhibits excellent conductivity, thermal conductivity, and corrosion resistance, making it widely used in industries, second only to steel. If the structure and die-casting process allow, using aluminum alloy is more cost-effective.

8. 6. The specific gravity of zinc alloy is about 2.5 times that of aluminum alloy, but the prices are comparable. Therefore, in terms of material cost, zinc alloy is two to three times more expensive than aluminum alloy. Many companies nowadays want to replace zinc alloy with aluminum alloy to save costs, but in some cases, it is not feasible because zinc alloy offers better strength, hardness, and formability.

    The differences between aluminum alloy handles and zinc alloy handles are mainly summarized in the six aspects mentioned above. It is important for everyone to understand these differences.
